Rifling:Projectile weight question

[pilot2001]

With a 1:10 twist, you can stabilize up to 200gr bullets. You can't really over-stabilize a bullet, at least not easily. As the twist increases, more energy is taken from propelling the bullet forward and put into spinning it. So shooting an excessively light bullet in a short twist is inefficient, though I don't know how much of a difference it makes.

My .308 has a 1:10 twist, and I've been shooting 168/175/185 grainers.

Cant over stabilize a bullet easily ? my 7rem has a 1-9 and it wont shoot 168's ... Its " over stabilizes " them , Drives 180's in a Canadian quarter at 300 yards.

I have had some success over stabilizing bullets. I know this because they blew to pieces half way to the target. Now Berger calls those "hunting bullets" not match.

Then their's the common thought that SMKs like mag length....

I'll admit, for some reason I've had a hard time getting SMK's to shoot. I know most would say that is odd. I've tried 20 off and 2.810. I do like the fact they don't shoot as consistant as others, because the other options are cheaper =)

In my inventory I have 168gr AMAX, and Hornady BTHP, I just purchased a box of 178gr AMAX, and I have about 50 odd SGK 165gr. Every time I go to a shop I always seem to go when they have no SMKs in stock.
