I have no experience with Defiance actions but if it can run the big Weatherby cals off the 378 case and the 338 Lapua, then of course you will be able to !
Have taken the 375 Mjolnir out for some more load development and took it for a 1000 yard walk, at this point have yet to chronograph my loads ( my Magnetospeed
chrono is finally on it's way, thanks Andy !) both of my Gamma Master Chrony's shook a tit and I don't bother setting them up anymore .
as soon as data is compiled I will post on this thread ! so far the Benchmark barrel has impressed the heck out of me, accuracy in load developement has been outstanding ! we will see how it performs in top end hot loads .
also really impressed with the new Nightforce ATACR ! 120 minutes of elevation on top of a 40 moa base ya can shoot way out to 2k+, just need to learn how and practice more, haha !
finally found a soft case that my Hammer Of Thor can fit in and zip up easily ! with the 33" bbl and the big Muscle Brake and the KRG Whiskey 3 chassis the overall length is 56 3/8" , the rifle fits comfortably with the Nightforce scope and bipod installed, absolutely awesome !! also got a case for my soon to be completed 338 Wolverine with the new gen 4 Whiskey 3 chassis !
contact Brian for the rifle cases @....
