How could or should the 6.5 mm Grendel be improved?

[woohoo]

are these bolts and extensions available for purchase? thanks,Kevan

Not at the moment. They aren't really a money maker so we produce the high volume parts most of the time. If we can get a few thousand 5.56 and 6.8 bolts in the bins we may machine a small batch later in the summer.

For target shooting and hunting the normal 9310 alloy bolts seem to work fine with PPC based cartridges. I just commented because a high rate of fire could cause reliability issues in a military weapon. 5.56 bolts break, the bolts with a larger recess are weaker and the cartridges create more bolt thrust so common sense says they should break sooner in the same type of condition.
