SR4759 which is a faster burner than H110.

Pistol powders, heaviest bullet gives less air volume in the case - my original problem using the Lapua 200 subs.

So here we are - almost at the end of a long journey.

9.8 grains groups well and runs at 1046fps average with an SD of 26fps.

Out of frustration I went to a pure pistol powder that I use for my 9mm with a burn rate equivalent to IMR SR 4756. Part of me wants to try a slightly faster powder again.

Thought of Trail Boss but I do not want to buy a canister that size.

Done the crimping.

Barrel is a local one that shoots 1/4 MOA with 155s.

Feel the frustration?

Using 240SMKs ==> 15.5 grains of 4198 = 1020 fps average (good) but Standard Deviation of 48fps (bad).

Then trying for accuracy at 100.

Just ordered some 240 grain SMKs to try. I'm thinking 15.5 grains should give me the starting point for the load.

Now what is the better muzzle velocity to head for? 1040 or 1050fps as average?
