Primer size

[Varmint Hunter]

Follow the guidance of the reloading manual(s) you're using for any given cartridge and you should be in good shape. Switching back & forth, regardless of powder charge, can result in changes in velocity and point of impact.

I thank you.

Personally I think keeping the temp in your reloading room at a level where your hands aren't sweaty is more important than gloves along with a handy rag or towels to frequently wipe your hands off.

I'm a guy who likes to really feel what I'm doing and I can't through even the best gloves.

I agree on those two mag primers will probably work best. I normally will try 250, 215, WLM, 215M in that order. If it's struggling I will try standard primers even in big mags. I will also run mag primers in all case sizes often. I currently load for 2-RUM, 1-28N. The RUMs are not picky, and bullet depending use 250 or 215M. The 28N I did load Dev. last summer and it shoots 215M great. Never even tried 250 or WLM because they are too precious. 250 has worked the best the most often for me.

When you say 215M you mean 215 Match correct? Or OP you can use regular 215s. I had a dramatic POI shift switching to match primers using 210m. Just a word of caution...they can and do make a difference.

I would suggest you wear kitchen mittens since you asked. LOL Seriously I don't even when mixing a bunch of brass in a tub for lubing....I like the feel.

Kitchen mittens and pink silk undies is what I heard works best for new loaders....less chaffing so they can load longer

I have used both. If my loads are under or about 75grs, I use Fed-210 primers. I am generally using H4350 or H4831 powders in belted mags. I do try all different primers during load development. My go to have been Fed-210 and not even the match primers either. The other is I generally use 26" barrel lengths too. I never had problems in cool weather either. (-20 below to 110+). I have had problems in hot weather with some powders, and I don't use them any longer.

What are the best gloves to wear when reloading?

The NONE brand

That rule of thumb for magnum primers with loads above 60g was coined by Speer…..who owned CCI at the time.
Guess marketing worked seeing as though EVERYONE now thinks that is what is required.
Carry on.

Cheers.

The M stands for magnum. The Gold Medal are the match primers.

Not on any I've ever bought. 210 large rifle 215 no M large rifle magnum. GM 210M large rifle Match....GM 215M ...large rifle magnum Match.
I was just clarifying for the O.P. thanks!

 

[West Calamus]

put WLRM use for 28 and 300
use 80-90 powder grains

Just figuring what primers t he at would be best? I'm going to be loading for 28nos and 300rum . Is there much difference between the large rifle and large Magnum rifle primers. Is there any benefits to one over the other
