My semi-custom 6mm Grendel bolt action build
#21
In my 6mmar it hit 3000fps with 2000-mp and close with cfe using sierra 95 tmks.
It was too hot for my 22 inch Krieger AR so I went with xbr or h-4895 for a more temp stable powder.
Accuracy is half moa.
The best coyote load has been using xbr and 75 grain v-max's.
It bugholes with that combination.
I have to try the 90 grain eld.
I get half moa with the 108 eld but been using the 75 v-max since it faster and exceeding accurate.
I'd like to get a howa bolt gun in 65grendel and cut to 16inches for suppressed deer hunting and use the 6mmar for coyote and long range target shooting.
I think you can reach 3000fps with 2000-mr and CFE using the 90 grain eld in a bolt gun using a chronograph and watching for a unusual jump in velocity and then back up a little.
My barrel shoots best at around half grain under max.
