The 260gr load was hard on one brand of brass, so I throttled it back to just over 2900fps recently, it still kills stuff dead, so no major issues with dropping it down a touch.



Are you running R17 for those numbers ??

My house load is a 250 SGK over H-414 for 3060 in a 26" barrel. I have a little wiggle room on charge weight. But not sure how much. I know when you get 250's - 260's running that fast, a few more fps is really splitting hairs...…..but ain't that what reloaders live to do ??

No, running the same powder as you W760 @ 90gr and a 260gr Accubond. Dropped back to 89gr.
I find my rifle faster than a mate with same barrel length, only difference between rifles are the chambers, mine has a 1/2”/.500” freebore that runs .3754”. His chamber has a .375”/3/8” freebore the same diameter.
With identical loads, his pressures out and mine is way faster than his.

Cheers.
