The loads that used to work OK in the old Mossberg wood stock (which I modified with pillars and bedding) were fairly light loads in the 250 to 270 gr bullet range, but they did not seem to shoot well in the new chassis. Today I shot a couple of 5-shot groups of 300 gr accubonds driven by RL 15. Here is an upper-end load shot at 128 yards:
I'm still getting used to the balance of the Oryx chassis which is similar to the other MDT all-metal chassis but still seems to shoot a bit differently, I think because of the fixed stock arrangement (not a bad thing, just different). The Oryx balances well enough that I could take shots without holding the fore-end and the rifle sliding back and not muzzle-flipping and giving me a scope-eye tatoo, kinda surprising considering the power and light weight of the rig. The two times I shot not holding the fore-end are the very highest and very lowest impacts. When I switched to holding the fore-end tightly and pulling in to the shoulder--I got the 3 shot splotch in the lower right.
Whaddaya think?  |
Sounds like a hard kicker. You shoot off bipod or rest? For bipod, do you preload?
