That's not bad. I never showed any pressure and I stopped at 81.0. Velocity seems a little low though. Is it a new barrel? The 300WM likes a little heavier bullets in my gun, 26" Krieger. The H1000 will probably work better for you with a little heavier bullet due to the burn rate of that...
The magnum primers were not around when the 300WM was developed, the standards primers is what that round was designed for in the beginning. The powders have come along way also since the 60's.
For what it's worth, my gun really likes IMR 4350 as far as accuracy is concerned, but I prefer the...
I have had good luck with H1000 and Federal 210M. The 215 magnum primers were erratic with ES and SD much greater. Different guns are going to react differently to components being used. I get less than .5 MOA with 180 AB's and 2" groups at 500 yards when I do my part. ES of 15 and SD average of 8.
I was not trying to be rude. I just assumed that most reloaders would have that equipment on hand. I too sometimes will inspect my brass and polish by hand, but in some instances, a tumbler comes in pretty handy if you are doing large batches of brass. Most people that shoot a lot just do not...
Are you being serious?
If you are to frugal to buy the standard equipment that most people accept as necessary for quality hand loading, then this activity may not be for you. A new FL sizing die is cheaper than a tumbler I suppose.
I had a Hornady die that had light rust but not pitted, ran it through a tumbler for several hours and it came out pretty good and has not given me any problems. It might work for you or maybe not, doesn’t cost anything to try.
I didn’t know that we could have extra of anything gun related. I’m speaking for myself of course, but I don’t have any extra of anything, seems like we may need everything we have on hand for future engagements that might arise in the coming months and years 🤔
