VTbowman Posted January 21, 2006 Report Share Posted January 21, 2006 Re: Finding the right bullet Ok I understand. Just how does it apply to those who have 1 ML. Does it break down the 100 some odd bullets out there for those singel owners? This was the one reason I sold my Remington 700ML. I could never find the right combo of pellets and sabots, etc... to shoot better then 3" groups at 100 yards. I did finally start using 250g ShockWaves and 2 Pyrodex pellets and that seemed to shoot better... Quote Link to comment Share on other sites More sharing options...
VTbowman Posted January 21, 2006 Report Share Posted January 21, 2006 Re: Finding the right bullet The ML I have now is a LOT different then that Remington. Its an Encore 15" pistol ML. The 209x50. I believe its a 1:28 twist and I use the same 250g T/C ShockWaves but have not figured out what powder or how much once I do. Quote Link to comment Share on other sites More sharing options...

AJ Posted January 24, 2006 Report Share Posted January 24, 2006 Re: Finding the right bullet Lee, I have the Greenhill Twist formula in a few of my reloading and ballistics software programs. When I compared theirs results with your equasion, yours was giving faster twists than the software programs. I used 2000 fps in the software and I checked 9 different ML bullets. The Greenhill formula (yours and software) defies my actual experience findings. I came up with the following (twist rounded to nearest whole): Weight Bullet Type S/W EQ 175 gr Dead Center 1:25 1:20 195 gr Dead Center 1:23 1:19 200 gr Dead Center 1:33 1:27 200 gr Hornady SST 1:28 1:25 220 gr Dead Center 1:30 1:26 235 gr PR QT40 1:27 1:23 250 gr HornadyXTP 1:59 1:46 250 gr Hornady SST 1:37 1:32 Out of my typical inline muzzleloaders, 4 of them have 1:28" twist barrels. The only bullet they all shoot decent is the .250 gr XTP. ther aer bullets each one shoots much better, but each one has its favorites. Knight Disc Elite .50 cal 1:28" Remington 700 ML .50 cal 1:28" TC Encore .50 cal 1:28" TC Black Diamond .50 cal 1:28" Savage 10 ML II .50 cal 1:24" Knight Disc Elite .45 cal 1:30" likes the 175 gr Dead Centers.

DannoBoone1 Posted January 24, 2006 Report Share Posted January 24, 2006 Re: Finding the right bullet The Greenhill Formula may be fine for giving one a ball park figure for a bullet to start off with, BUT it leaves out a very pertinent calculation.........bearing surface area......and that DOES make a difference.

AJ Posted January 24, 2006 Report Share Posted January 24, 2006 Re: Finding the right bullet Lee, I was not trying to point fingers, just wondering why the delta in data. I have used the Greenhill twist program for centerfire and it has worked pretty well. I dunno. I 100% agree that overstabilization is usually not that big of a deal, but understabilization is a killer of accuracy. DB1, Bearing surface does not have anything to do with what spin it takes to stabilize a given bullet. It all about length and spin rate, as long as you have enough bearing surface to impart the necessary spin, its moot after that. Bearing surface is a contributor to accuracy and pressure on the other hand. Quote Link to comment Share on other sites More sharing options...
