My Experience with GS Custom Bullets

100 fps increase with magnum primers is signficant. I don't see that much difference with 6.8. I will have to try my 270 were there is significantly more powder. BTW, 80gr GMX performs much bettern than 80gr TTSX. It holds together much better and has a bigger dynamic range.

The problem is that fiocchi large primer are faster than the CCI250 magnum primers.

Doesn't sound like a problem to me. Faster and just as accurate sounds like a winner to me.

The problem is speed variation on the Fiocchi primers... CCI is much more consistent and you see it in the groups

Stick with the CCIs. Accuracy always trumpts all else. The 80 TTSX doesn't hold together inside of 125 yards with a mv of 3250 from what I have tested.
