What speeds are you getting with 6mm br with 105s

[Kracken McGraw]

I agree. I have pushed 2900+ and they do show flattening primers. Now I keep mine in the mid to low 2800fps range. 25 reloads on two batches of Lapua, 30 on the Peterson. The brass doesn't stretch as much either.

Information like this from you great guys is why I own a chronograph.

Dang, I need to do more testing....

30.3 R15, CCI 450, and a Berger HVLD is only getting me 2780fps out of a 27" barrel.

I had suspected this was slower than average.

2780 is the sweet spot for me with Sierra 107's.

With 105 hybrids, Lapua brass and 30.1 grns of Varget or N150 (interchangeable) I get 2850-2860. No pressure and holds accuracy to 600+

Nothing wrong with being in the 2700s if it shoots there
