doubleA Posted August 26, 2010 Report Share Posted August 26, 2010 Been shooting the big boomers for distance and decided to go small this time around. My new build is going to be the diminutive 223 IMP. Having the throat cut to maximize the 75gr Amax OAL in the Accuracy International magazine. Now it's just a waiting game till it's done.:gun2: Trued M700 SS short action, AICS 2.0 folder, Rock fluted1:8 MTU contour, threaded for muzzle brake/can and finished @ 25", Jewell trigger, Badger rings and base, APA recoil lug and custom bolt knob so far.

I always thought I was pretty well informed when it came to rifles but I only understood about half of what yoou are talking about. One thing I do know is that if I don't know about it, it is expensive. Are you going to have to turn in the kids college fund to pay for this. LOL. :gun2: Quote Link to comment Share on other sites More sharing options...

doubleA Posted September 1, 2010 Author Report Share Posted September 1, 2010 Sorry if the post was in greek. Basically it's going to be a 223 AI(improved so the case holds slightly more powder) repeater(magazine fed, 10 shots) in a aluminum chasis( folding stock) with a big barrel made to shoot heavy bullets. Should weigh in around 15-16 lbs when complete. Had a problem with FedEx delivery to my smith but the parts finally got there. Now's it's just a waiting game.:cool2: Quote Link to comment Share on other sites More sharing options...
Adjam5 Posted September 2, 2010 Report Share Posted September 2, 2010 Charlie...How heavy of a .223 bullet can you get? The heaviest I have seen is 75 grains and that is the Hornady TAP ammo. Will the twist be slower than 1:7? Quote Link to comment Share on other sites More sharing options...
doubleA Posted September 2, 2010 Author Report Share Posted September 2, 2010 Anthony, there are several makers that produce 90 gr. .224" bullets. I am having chamber throat cut for the 75-80 grain Hornady AMax as the barrel is a 1:8. The super heavy 90's will require a 1:7 and usually have to be single loaded due to their length something I did not want since I wanted a repeater. The 75gr Amax shoots extremely well in my Sabre Defence 1:8 Quote Link to comment Share on other sites More sharing options...
Strut10 Posted September 2, 2010 Report Share Posted September 2, 2010 Had a problem with FedEx delivery to my smith ......... That's what you'll have when you ship with them minor leaguers. Now you're just like a kid waiting for Christmas or your birthday. Yeah, the wa-a-aiting is the harrrrrrr-dest part. :D:D Hope it comes together for you soon. I wanna see a range report!!

The 75gr Amax shoots extremely well in my Sabre Defence 1:8 So due to the longer , heavier bullets . The case needs to have some extra room in the chamber. They can't make the bullet fatter, that will change the caliber, so the OAL will increase to accommodate the larger bullet...Correct? So that is where the Improved part of the case comes in. A larger case for the longer bullet. That is a question . Quote Link to comment Share on other sites More sharing options...
doubleA Posted September 2, 2010 Author Report Share Posted September 2, 2010 Yes, due to the longer bullets, case capacity is used up if the bullet were to be seated to a normal OAL. The improving of the case is only slight, the shoulder is blown out slightly and angle increased a bit. As you know the capacity is not much to begin with in a 223, somewhere in the 27-28 grain max. With lighter weight bullets the 223 AI is very efficient in pushing up the speeds, while it's no 22-250 or 220 swift it does alot with relatively small amounts of powder. So all I am is doing in trying to get a little more powder capacity and bei able to seat the bullets out as far as I can. The good thing is that 223 brass is plentifull and cheap and can be fired in the 223 AI chamber. Quote Link to comment Share on other sites More sharing options...
Adjam5 Posted September 2, 2010 Report Share Posted September 2, 2010 Thank you Charlie for explaining that . I hope to be as well versed as you are one day regarding firearms . Quote Link to comment Share on other sites More sharing options...
doubleA Posted September 5, 2010 Author Report Share Posted September 5, 2010 Anthony, here is an example. As you can see the 80gr is quite long for it's caliber Left-Right .50 cal 750gr AMax, .223 case, .224 cal 80gr AMax, .224 cal 50gr Nosler BT Quote Link to comment Share on other sites More sharing options...
doubleA Posted September 28, 2010 Author Report Share Posted September 28, 2010 Ordered the scope for it today, should be here in a week or so. Sure am looking forward to shooting this thing. 3.2x17 SN-3 TPAL Quote Link to comment Share on other sites More sharing options...

dbHunterNY Posted September 29, 2010 Report Share Posted September 29, 2010 what kind of velocity are you thinking you'll get back from additional amount of charge? will you be back to around 2900-3000 fps you think? i shoot 60gr Vmax bullets out of my .223 Rem. I've got to think that added 20 grains and extra push behind the bullet would help a lot with bucking the wind and maintaining momentum. i haven't shot a .223 enough to know how much of a difference it'd make.

doubleA Posted September 30, 2010 Author Report Share Posted September 30, 2010 dbHunter, without actually having the rifle completed I can not say. Most folks are getting between 2950 and 3100fps with 75gr Amax and slightly lower with the 80's. It's going to be dependant on how "fast" my particular barrel is.

doubleA Posted October 4, 2010 Author Report Share Posted October 4, 2010 Recieved the scope Friday and decided to see what it would look like on a rifle. It's built like a tank, here it is mounted on a FNH SPR. Quote Link to comment Share on other sites More sharing options...
dbHunterNY Posted October 4, 2010 Report Share Posted October 4, 2010 Looks awesome on that rifle. Can't imagine that looking bad on the one in progress. Are you finishing the stock any different or leaving it olive green? Quote Link to comment Share on other sites More sharing options...
