What are your thoughts on PMC brass. I have done a few with Winchesters and all went well but the PMCs are a lot harder to decap and size. I just mean it's noticeably harder to pull down the arm on the press.

| I had some PMC brass in the past in .223Rem, no problems, and I did not notice any difference in force needed to resize, but maybe my cases were a lot smaller than yours.

I haven't noticed any difference in 270 or 223. RD
BTW Claudster, I was up in your area yesterday. Got as far as Freedom. I do make Oconto about once a year.

Thanks for all the input! I just went and weighed the two cases, Winchester and PMC. The Winchester was 170.2gr. with a primer and the PMC was 177.4gr. without a primer. Just more brass on the PMCs I guess.

| Claudster, If cases have more brass and the outside is sized to the same specification then the inside will have less volume. Less volume makes higher pressures. This isn't normally a problem unless you've worked up loads for the lighter cases that are pushing the max in your rifle. Put that load in a smaller volume case and you'll have pressure problems. Just bear in mind that you'll want to work up to a max load. Otherwise PMC cases work fine. RD

I like PMC brass. I have had good luck with it in reloads. From the weight you quote I am guessing it is in 308. 177 grains is what my 308 Lake City match brass weighs. Typically Winchester brass in 308 of 3006 is on the light end of the scale.
At any rate the weight difference is not troubling to me and PMC seems to last well.
Good luck, have fun.

I have PMC in 38, 357, 9mm, 45 APC, 223, and 30-30 and have had them for many years. They all required more pressure on the press arm to resize.
When I would resize large lots I could tell the PMC cases by the feel.
I wandered if the cases may be thicker also and weighed them against R-P and Win. cases and found the weight was "sooo" close that thickness was most likely not the reason.
I did not have the means at the time to check the thickness of the walls then but the base thickness was the same and should not have made any difference in the sizing pressure.
I concluded that most likely the brass is harder (annealing or lack of) than other brass.
NOTE: I use a universal de-capper to de-cap all cases prior to tumbling and noted some PMC brass required more pressure. This was mostly in the 45 and 9mm and was not random with in a lot. I did have about 10 38 cases than the primer did not come out of but only punched the bottom of the primer out and left the side in the case.
