6mm MachIV

[scope eye]

I haven't posted in a while so here is what I have been up to, I already had one in 12 twist and was making one for someone else and hate renting a reamer for just one barrel, it seems like just such a waste so I had another one done for myself. It was one of my first wildcats and is one of my favorites if not my favorite. Here she is, when the cases are fire formed they hold 80gr+ powder, 107gr exit at 4000 fps but Now with this 10twist I am going after the 115gr, 120, 125, and 130gr bullets with this one. they other member had a 9 twist done so he can shoot anything he wants also.

A fully formed case "Right" and a 7mm RemMag necked down to 6mm by using a 243wssm die "left" 264 WinMag brass also works well, I get over 4000FPS with a 107gr Sierra while fireforming. And with that extra 7gr more capacity from a formed case and not losing any energy due to fireforming those 107s numbers are in the stratosphere.

Reach out and touch something. 9 twist?

A 10 Twist will stabilize anything, so a 9 Twist won't really make a difference.
