Thinking about a Rem 700

[Blowby]

Ammo is a large part of the solution. If the gun is setup solid first, then loads developed for it, you should have no problem hitting 600 consistently. I shoot my 20" rem700 out way past that with the only accuracy issue is my wind calls so it's not the barrel length. If I did have a longer barrel then my MV could be developed faster to help in drop and reduce the deflection, just a small amount, from wind.

BTW: Dave if you're free today we can go shoot my 20" Rem out to 700+ to see that it's not a problem.
