Tell me what you think. I bought a brown box of federal 300 wsm 180gr power shok the comes with 10 boxes of ammo (200 rounds). I have shot this before and it's quite hot with pretty flat primers and since brass is hard to come by these days I thought maybe I should pull the bullets and reload it all with the same powdr but 2 gr less. This would be a lighter load to fire form the brass and hopefully make it last longer with the primer pockets not giving up in 3 fireings.

Thoughts?

If it were me / myself / personally, I'd pull the bullets. Just the fact that you're asking leads me to believe you have safety concerns and we should never have those.

The Winchester 22-250 white box (40gr bullet, 50 rounds I think). The head spacing on those rounds would fit the sloppiest of chambers. If given a box, I would pull the bullets and reclaim the brass. But then again, that's just me.

I've done it before, no big thing, though sometimes you might need to size the necks again.

Alright seem like this is pretty straight forward. It's all the same lot number so I will measure the charge weight of 10 and reload them all with a bit less. Certainly don't want to waste the almost 2 lbs of powder.

Just another thought you could drop in some 165s with powder charges as are and be Milder!

I'm not excited about Win ball powders, and considering the current problems with Win primers I'd pop them out too. I wouldn't feel bad at all if I only used the brass.

Federal ammo has win primers?

No...

HaYen mentioned Win White Box ammo and I hit the Quick Reply.

I think your plan is a good one, but 2gr may still be in the warm zone.

Based on my experience with other Fed brass I might drop it down another grain or two lower to start.

WSM rounds are rated at 65k psi max and I don't run field loads in any round that hot.
