Re: Savage magnum bolt head mystery?
Great info. It all makes sense now. I knew that Savage went to the large shank barrel in the WSMs and RUMs but I didn’t know that they beefed up the bolt head. I’ve been using a standard magnum bolt head with a standard shank 28” 7mm WSM barrel running 168 grain AMAXs at 3,150 fps with no issues so it makes me wonder why Savage would do this. I heard that it was to get “more margin” for their legal staff but that is just rumors.
If it wasn’t for the lawyers but for the engineers, worst case, I suppose a lot of rounds could beat up the thinner bolt lug and warp it. But if you mix and match, bolt heads are easy to check, cheap to buy and take maybe 5 minutes to change.
By the way, the PT&G website has no option to select a WSM bolt head, only “magnum” and I have one of those here and the lug measures 0.441” (the same as the Savage standard magnum lug as well as the non magnum lug).
Looking at the high quality of the PT&G bolt head and the difference in the steel I’m guessing that it doesn’t need to be thicker for the WSMs. Also, given that the thinner bolt lugs handle a 300 Win Mag which runs a mere 1,000 psi less, I don’t think I’m going to get too concerned.
Thanks for solving the mystery.
