Haole Posted May 17, 2014 Share Posted May 17, 2014 A question for long range shooters: From my days shooting scoped, bolt action rifles for accuracy, I learned to weigh cases and bullets and shoot similar weights in the same string of shots. How necessary is that with black powder rifles. Im shooting a Winchester 1895 clone in 45-70 and a Sharps clone in 45-120. The bullets I find (all well cast from reliable sources) vary in weight by about 10 grains. Im grouping those bullets in half grain increments. Am I on the right track, or am I being a bit too annul with all this? Haole Link to comment Share on other sites More sharing options...
Cliff Hanger #3720LR Posted May 17, 2014 Share Posted May 17, 2014 The difference in weight can be the bullets themselves. Sorting can help But it can also be the amount of lube variation on the bullet which will not effect the shot due to bp soft lubes being left behind in the barrel or at exit.

FriscoCounty Posted May 17, 2014 Share Posted May 17, 2014 Nope, you're not. At CAS main match distances it doesn't matter. For long range, getting all the variables out is a good thing. Link to comment Share on other sites More sharing options...
Mad Dog Jack, SASS #77862 Posted May 17, 2014 Share Posted May 17, 2014 I sort bullets by weight and am resonably carefull about loads and loading,but I am not a serious long range shooter. The serious ones are on BPCR forums, and they are picky. Link to comment Share on other sites More sharing options...
John Boy Posted May 17, 2014 Share Posted May 17, 2014 How necessary is that with black powder rifles. At 1000yds, 1-2grs variance will vary POI about 4 MOA Keep the bullets in 0 to 0.5gr variance for better accuracy at mid and long range distances Link to comment Share on other sites More sharing options...
Haole Posted May 18, 2014 Author Share Posted May 18, 2014 Thanks guys. I'll keep sorting and weighing. Haole Link to comment Share on other sites More sharing options...

At 1,000 yards. 4 moa is approximately 40 inches. I sometimes shoot 1,000 yard buffalo matches using swaged BACO bullets which are usually +/- 5 grains. Generally, I do OK with them. When I cast my own, I group them in batches of +/- 0.5 grains but I don't index them. If the wind is squirrely, it does not matter what you are shooting. Each shot is a new adventure.
