I've been reloading now for over 30 yrs, please don't try to insult my inteligence with the A and B brand. I have used the same type projectiles in all I load, rifle and pistol both. I have NEVER had any type of malfunction when it comes to reloading or my reloads, and what do your barrle blanks have to do with anything.Amrhein
I would, but that's the first page I used.
My point is that you can NOT look at a data page and see where a given set of load data came from.
BTW, you do know that one of the biggest variables in load data is bullet design/construction, don't you? Switching from Brand A to Brand B and making no other changes has blown up many a rifle.
But, if your happy using second hand & obsolete data in your rifle, than all I can say is "go for it".
OTOH, my barrel blanks cost almost as much as a Mini, and by the time they're threaded, chambered and installed my barrels are worth a lot more than a stock Mini.
