I am putting together my long distance hunting rifle. I am using a Browning A-bolt 270wsm I am going to either have Leupold custom build me a scope or I will go with a nightforce nxs. I am going to be using a bullet coefficiant of .496 or hopefully above .50 if I can get it built for me. (I have a guy in canada who working on it for me.) I have taken an Elk at long range with a 270 win but want this rifle to be dead on at above 500 meters out to 1000 meters.

Now to my question; Can anyone tell me there expierence with an a-bolt at long range?

....I've taken some shots in the 300-400 yd range...with my .338 Browning A-bolt....and-

...Yep.....and I wouldn't recommend attempting any shot (on large game,especially...) at ranges like what you are talking about...(500-1000 meters??!:rolleyes:)....in my opinion , it just isn't good- or smart - hunting ethics to try that....it's not fair to the animal to try shots like that, and risk wounding your quarry....WHY??!:confused::rolleyes:

-If you want to play ballistic games and experiment with scopes....set all the pumpkins you want, out at ranges like that, and get your kicks watching them explode...

-otherwise.....how is that even remotely close to hunting??:rolleyes:

...I'll be blunt with you:D...I should hope never to hear of anyone coming up HERE to try a stunt like that on these Dall sheep that are so precious to me...and to any hunter that works for the shot,after a long and ardurous stalk...(regardless what or where they hunt...).

-Oh...-Welcome to the Realtree forums!...:D:D:):cool:

500 yard shots on big game animals are definitely do-able with the accuracy levels I have seen from Browning A-Bolts. I imagine in most cases, a feller could get himself closer than that. But it's not an unthinkable thing if closer's not an option.

1000 yard shots on big game animals with an A-Bolt.......or any other sporter??? :cool: Most guy's would have a rough time hitting a pickup truck at 1000 yards with their deer rifles. You'd better spend some looong hours punching paper at 1000 with that Browning. I believe you'll draw your own conclusions.

Holy crap fellas calm down!! I mentioned taking an elk with a 270 from long range: I never said how long that range was so the "Hunting ethics" comments are way off base. I am an archery hunter for big game and for the last 14 years have pretty much exclusivley hunted with my bow.

I will add a little information to this thread so it can get back on track; I am going to be hunting coyotes and prairie dogs from 500-1000 meters. I have hunting partners that are doing this with a .308 and a 7mm stw. I currently have a 3x9 leupold on my rifle and am hitting a 7" round steel gong at 800 yards. The problem is that have it sighted in at 500 so trying to shoot under 400 is really dumb. Hence the reason I am looking for a tactical scope, I have decided on the nightforce btw. I agree that trying to shoot big game at extreme long range is poor judgement but sheese so many people get high and mighty on these forums and take a tone that is confrontational when they are uninformed about the situation they are getting riled up about.. Anyway thanks for the warm welcome

I read, re-read and re-re-read your original post. I still took it to infer you were wishing to shoot elk at 1000 yards. I, for one, don't claim to be "high & mighty". I'm just a realist and try to steer folks in the right direction when it appears they are about to do something they probably ought not. I'm glad that you've clarified your intentions.

Most A-Bolts I've seen or monkied with are capeable of MOA accuracy or maybe a tad better. To sight in dead nuts at 500 then shoot to 1000, a scope with good and repeatable adjustable turrets is a must. So is a good ballistics program and painstakingly prepared reloads. I'll be interested to hear how your setup works out.

Welcome to the Realtree Forums, BTW!! ;):D

....Interpret it as "high and mighty" if you wish...but I don't buy your seemingly innocent and hurt reaction to the initial posts on this thread...I was not "uninformed of the situation"...you changed it, conveniently, in your next post...

-I couldn't believe it when I read your cover-up explanation ,that you would be "varmint hunting"...I don't buy it.-I purposely, in my first post , left out my initial thought to include my opinion, that VARMINT hunting at these extreme ranges WERE acceptable.....I left it out, because it was absolutely clear in my mind from re-reading your post as well, that you were NOT preparing this ballistic and scope combo for varmint hunting...

-My passionate opinion on this,and my feeling of being compelled to state such, goes beyond the usual"differences of opinion" that are in the arenas of ...."Knockdown power vs. Penetration"...or..."What would be the Minimum Cailiber to hunt-(take your pick-)"....or the proverbial bickering between the diehard reloaders over "split grains"-("split hairs"):rolleyes:-

...My opinion is prodded so strongly by my deep belief and respect for the creed of Fair Chase....

....In a hypothetical and somewhat controlled situation of target shooting ...the ballistics calculated,windage factored in, and scope selection and adjustment at these extreme ranges,are an art in themselves...it certainly has its place...

-Yet...the same stupidity attempted within the hunting world...with all its variables...and most of all the crucial importance of the act of ethically harvesting a big game animal ,with the best effort put forth for a quick,clean kill, and recovery......really yanks my chain...

-I also question what you really meant when you said that you are "an archery hunter for big game and for the last 14 years have pretty much exclusively hunted with your bow".- Something just doesn't add up; and your hunting principles ,ethics, and intent, do not speak with the same heart as that of the true bowhunter...

....I implore you to really think about the higher meaning of the Hunt...

I would keep the NF and ditch the a-bolt in 270wsm and opt for a remington based rifle maybe in 7mm wsm, you just have many more selections in aftermarket parts/bullets. When you start to get out past 500yrds I really think on big game you are better off with something in .338 but that's just me.

I am not familiar with them myself, but from what they show on their show "best of the west", the huskemaw scopes may be a consideration. Far as a rifle platform, I like the a bolts, but if I was out to build a long range rifle, think I would have to agree that a remington 700 would be the platform I would build on.

AK if what you just posted isnt the exact definition of "High and Mighty" its gotta be dang close.. ROFLMAO. My archery background speaks for itself to people who know me. If you need references call my employer Ruggs Ranch LLC and ask them for client comments. Oh yeah I guide for them Big game and upland game. I am proud that I have a waiting list and return clients that come year after year to hunt with me. To clear up the archery comments I hunted with a rifle the last year that my grandfather hunted and then again the year before my father died. Other than that I have guided the rifle seasons and hunted for myself with my bow. I agree with you 100% on what you are saying about ethics and respect for your quarry but you dont know me and for you to begin to attack me personally is laughable. I am sorry that the way I posted my first post was confusing. It was not my intetion. The longest distance I have killed a big game animal is 480yds with my 270win. I am not looking for a fight or an argument here. I will not be responding anymore except to provide info from my limited knowlege base or let people see how my projects are progressing. I hope that in the future good solid info and fact can be traded here on this sight.

Out of curiousity, how much energy is a round from a 270 wsm carrying at 1000 meters anyway?

For a 140grn bullet with a BC of .31 about 700 ft-lbs. With a BC of .5 it could be double that.

I don't shoot that far but I've spent time on the range with guys who do and can shoot amazing distances with astonishing consistency.

Personally, I can't. So I don't. But I do believe it's possible. So I won't judge based on my own personal capabilities.

Happylilcuss,

Nightforce has an excellent reputation with the long range guys. The Brownings also do as well.

7mm might have been a more prudent bore size choice. There are quite a few high BC bullets to choose from in 7mm. The .270 bore IMHO is limited by comparison.

Leo, your numbers don't jive with the ballistic programs I have.

I punched in a 150gr Barnes MRX BT at 3000fps launch speed. With a 500yd zero there would be another 240" (yep 20ft) of drop at 1000yds and a paultry 504ftlb of energy...

I'd be right suprised to see a factory A-Bolt shoot hunting grade bullets well enough to do much of anything at 1000yds or meters for that matter...

I'm with doubleA on this one. Keep the Nightforce and put your money into a Rem 700 in either 7WSM or 300WSM...

If you use that speed (3000fps) and BC (.425) for the 150grn 270 MRX and your software uses the "Flat Base" drag model you will indeed get about 500Ft-lbs at 1000yds. With a boat tail drag model which I believe is more appropriate for the MRX. You'll get almost double that figure. ;)

what does it matter what you do, to have to do with shooting at 1000 meters, you should be able to get a little closer with your above background

...I'm still am not cutting him any slack.:cool:

...His origional post was simplistically inquiring and groping at a set-up to take elk at this range.-and I don't like it.

I did do some homework, though...and it seems that HYPOTHETICALLY...the optimal coefficient outcome at those extreme ranges would perhaps be from a .300 Weatherby Magnum,220 grn load.

Don't worry, I don't have anything more to add...:rolleyes:

AK contribute or please stop coming to this thread. It the beauty of the internet you dont have to go anywhere you dont want to be. I appologised and continue to appologise for the confusion. I take full blame for the misunderstanding.

Anyway, I found a neat ballistic program and put in some numbers. According to JDM the "Maximum distance output of a Hornady 150g sst in .277 traveling at 3225fps at the muzzle at 80 degrees F 29.92 inhg at 10%rh (I live am living this summer in Nevada were lucky to 20% in the summer) at 4500ft the terminal range of the .277 would be 6703.3yds at 101.6 foot pounds.

http://www.eskimo.com/~jbm/cgi-bin/jbmdist.cgi

The same setup at 1000yds produces 906.1 foot pounds. with a 10mph crosswind downrange.

http://www.eskimo.com/~jbm/cgi-bin/jbmtraj.cgi

I think these numbers are not too shabby myself.. But its just to build something i have not ever heard of and I am really fond of this caliber.

Personally I have this 700p remington .308. I have not used it for long shots yet. I purchased this custom for Coyote as they are plentifull in my area. Local farmer's are getting calf's eaten even at the barn. We sometimes hear them howling even from inside the house. Anyway it as a leupold tactical 4.5 to 15 scope on it. Bull barrel and drives tack's. Incredibly acurrate. I love more my a-bolt 300win mag Boss but I have to admit this remington is a lot more accurate.

I am putting together my long distance hunting rifle. I am using a Browning A-bolt 270wsm I am going to either have Leupold custom build me a scope or I will go with a nightforce nxs. I am going to be using a bullet coefficiant of .496 or hopefully above .50 if I can get it built for me. (I have a guy in canada who working on it for me.) I have taken an Elk at long range with a 270 win but want this rifle to be dead on at above 500 meters out to 1000 meters.

Now to my question; Can anyone tell me there expierence with an a-bolt at long range?

I have enough experience with the A-Bolts to know that if I was building a gun for 500-1000 meters it would definately not be my choice. While they are a viable option for 100-500 yards, if you want and expect true consistency and accuracy out to 1000 I would choose another platform to build from.

As far as cartridge selection, I would be thinking 7mm STW or 30 caliber magnum. But, that is my preference.

Here's a place to go find some definitave answers for your quandry. http://forums.accuratereloading.com/eve/forums/a/frm/f/3221043.

I'd really like to see their response to this question.

Have a Great day

Hey, Kathleen was here first :D and that's a pretty bold statement for a guy that's only got 5 posts, (and the first 2 don't count..LOL)

Besides...she's cuter than you. :D:p:p
