"The Farther One Travels, The Less One Knows" Barrell / Reloading Questions

I got lucky when I built my son's heavy barrel 223 using a factory stainless fluted barrel. I's a 1 in 9 twist and loves the 75 gr A-Max bullets. He shot at 400 yards for the first time Sunday and managed a 3.69" group at that range after getting his elevation right. He fired 6 more shots and all those averaged 4.59" with five going into 2.73".

Sinclair (part of Brownells), carries small batches of bullets (25-30) so you don't have to buy by the hundreds. Not the cheapest way to reload, but not dropping a ton of cash on the unknown.

RPM is what stabilizes, and the LENGTH is what needs stabilizing, not the weight.
RPM is a function of both twist and velocity. No two barrels are created equal, but here is a calculator to get you started:

Look up your specific bullet from the tab on the left, then come back and fill in for your specifics.

DITTO what darkker said. Amount of bullet jacket in contact with the rifling...hence...length of bullet.
