Here is an example how our reloading manuals have been adjusted for our safety. Or lawyerized.
First pic is of the old Sierra manual from the late 60's and the other just a year or two old.
Using 3031 max charge is 47.9 grains and then the later book 41.1 grains.
Did his cases show signs of overpressure?
So over 30-35 years the loading data has decreased by 16.6%.
I personally still load some things near the high side, and use data out of older manuals.
I have a 45th Lyman manual printed in 1970 showing many loads in most calibers that are well above currently printed standards. I believe that more precise testing methods, increased liability concerns, and changes/additions to the powders we use are all responsible for those changes. I remember when BlueDot changed and I couldn't use it in my 41 Mag any longer. Man, was I bummed.
Back to the other thing,
I know you can stuff 60gr of RL22 or 59.5gr of IMR4831 in a Remington case and seat a 180gr Partition on top of it. There's room.
Was it a 30-06 Ackley Improved? 57gr of Varget behind a cup and core, bonded or partitioned bullet in an Ackley case wouldn't be that far off.
In a regular ol 30-06 case, nah, that's too much. At least it seems to be.
Flat primers? Yeah, some get "flatter" than the others, but I doubt that any healthy reload leaves much of a radius on the primer. The fact that he's not experiencing sticky bolt lift is encouraging, though. In the days before guys had easy access to reliable load data and chronographs they would increase powder charges until the bolt got sticky, and then back off. Or not.
My 06AI is my gun version of my hot rod. I strive to stay within the safety standards, but I put this thing together to be able to stretch it's legs. I have a reliable gun that performs like a magnum, but doesn't weigh like a magnum. When it was just a regular ol 06 I loaded it to the gills because I safely can. I use my chronograph and work up my loads while paying attention to the bolt lift, velocity and the condition of the expended case.
It would be difficult to try and enforce a safety rule just because you believe he's pushing beyond the limit. What are ya gonna do, break down a couple of rounds and check them, like the NHRA having you tear down an engine?
I guess next time you do like last time. After expressing your concern over his supposedly aggressive loads, park him at the end of the firing line and keep a buffer zone.
