almost all of my rifles slot in the shorter class, so I tend to make use of the quicker powders. 3031 is often my goto powder for most effective accuracy from the limited barrels(with some exceptions), and in some cases some from the sporter and longer barrels. I have also uncovered that velocity decline in the shorter barrels is much less (meaning my velocities in a short barrel are nearer to posted velocities utilizing 3031).
Just picked up eight lbs of. IMR 3031 in search of any person's pet/favorite loads for .223 rem. I have never made use of it ahead of I Ordinarily use Varget or earn 748 but was capable to lay my palms over a 8lb keg so I did wanting to get Varget continues to be a ache from the backside.

As you may have collected from the above posts, There is certainly far more than strain and velocity to take into consideration in accuracy loads. The strain curve, bulk of your powder, and ease (and for that reason consistency) of ignition all have an effect on the make any difference. A quick powder may not provide you with the greatest velocity on your peak force price, but to get a presented velocity it provides lower muzzle blast than the usual slower powder, which has an effect on Preliminary bullet yaw in some cases adequate being observed in group size.

IMR 4759 is greatest for really read more light-weight loads as its manufactured for that and substantial bulk to reduce the probability of a double cost.
everyone ever use this imr 3031 powder? Did it perform effectively? What calibers and grain wegjts do you employ it for? My reloading shop had some I purchased a lb to try.
"supplied sufficient penetration, a larger diameter bullet will have an edge in wounding success. It will harm a blood vessel the smaller projectile hardly misses.
222 Remington rifles. That said, I switched to BLC2 and W748 because they evaluate like h2o through a powder evaluate. IMR3031 with its prolonged kernels was a pain to load and doesn’t evaluate perfectly.
Note the the order of 3031 and 4064 is reversed from most melt away fee charts. It's because true samples were measured in a lab for the QuickLOAD database, and in The actual great deal tested, which is precisely what it turned out to be.
All else remaining equal (and it Just about never is) even larger bullets have a tendency to work superior. 44 AMP
