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

[GaCop]

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".

SWEET! You can be very proud of him! Hoping I do that well when I start "getting out there"! Brian

I read somewhere that there is a company that will sell you small amounts of "sample" bullets to try in your gun, for a reasonable cost. I FORGET where I saw this info- any one know? Appreciate any leads- I'd love to experiment.

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.

Bullet WEIGHT means very slightly more than NOTHING when it comes to stability and twist rates, so get that out of your head. People who talk weight: 1) don't know chit. 2) are making a very generalized comment.
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.
