New guy here as well as reloading!

[436]

Good morning fellas! New to reloading, and with the shortage of components it makes it tough. Anyhow, looking for any input on the use of N560 in a 270 WSM, 7mm RM as well as 338 LM. There is quite a lot of information to try and soak up when just starting out, just trying to look for some good advice specifically for these calibers. Thanks in advance!

Welcome you'll have fun here and perhaps pick up a few things along the way. Cheer's

That's not a bad practice but it's certainly not necessary. The first designated "magnum" primer was the federal 215, which was created to
Ensure reliable ignition of the pile of slow burning powder in the .378 weatherby when it first arrived. That's about twice the 60 grain capacity cited here. Worth noting then that the .375hh and offspring, the 404 Jeffery (on which the RUMs are based) the 416 rigby (on which the ops .338 lapua is based) and even the mighty 505 gibbs (on which the cheytac cartridges are based) never had magnum primers nor had anyone heard of such a thing and ignition wasn't a problem with these.

Now I do use magnum primers in my 300
Win, but would have no second thoughts about standard if the groups were better.

ive heard people say magnum primers ensure reliable ignition in cold weather. I live in northern Saskatchewan, never seen cold, even nasty cold, in any way cause problems with standard primers.

I honestly don't see any NEED for magnum primers as far as reliability goes. But in some cartridges they improve numbers and consistency so I'm happy to have the option.

only exception standing very clearly in my mind is heavily compressed charges of ball powder, in any rifle cartridge I use magnum primers if I have to do that but to be honest I just don't like ball powder now so it's rarely required. But that's the only hangfire and the only fail to fire I've had...compressed ball powder with standard primers.

Well I guess I learn something new every day I have always used magnum primers in my 338 Lapua magnum maybe one day I will try non-magnum primers and see how it acts it's nice to have options

I use RL16 in my 270 wsm with a 130 gr bullets, Nosler AB, BT's and Berger CH have all shot well with 58.2 grs. Not super fast, the Berger CH is 3089 fps, trued at 1000 yards. But its accurate.
In my 7mag I use H1000 with a 180 gr Berger vld-h but it needs a 8T barrel I believe. H4831sc works well with 140 to 168 gr bullets in the 7mag. Pretty sure you'll need a powder like H1000 or Retumbo or slower for a 338 LM.

I do not shoot 270 Wamitchill or 338. I do shoot 7mm rm. but I use n160 for it, because it yielded the best results I also had good luck with imr 4350, but the n160 was just a bit more accurate. Look at your load book and see if they list that powder and try it your gun might love it. Also Vihtavuori has an ap that you can record your recapped and results in, along with the ability to look at their recipes. Hope this could be of a bit of help. Any big problems that come up put up a post most are very willing to help. Good luck.

Welcome, Roll Tide.
Those are three interesting calibers you will be reloading. Keep good notes. I use a sharpie marker on the brass case to remind what is in each case. Flat base bullets are sometimes better inside of 200 yards. Try not to go full throttle yet. I recommend searching for the low node. Try to figure out "the ladder" in testing loads. Probably saves powder. On the case head I draw a straight line each time I fire a case and it tends to stay readable and gives me an idea if how many times that case has been fired. Again stay low node and brass may last longer.
Enjoy a good pass time reloader adventure addiction. If ever in doubt pull that bullet.
Primer pockets can get worn out.
Russia primers can be slightly undersized leading to blow out...not fun. Stay low bro

No need to insert the "roll tide" on a shooting forum. I'm a Dawg and actually fortunate enough to have pitched and won the 1990 CWS our first and only. I was a small piece of a big pie and an unbelievable team. Welcome to the group and these guys are great with a wealth of humble knowledge.

Welcome aboard. I mostly lurk about and read the advise from others. I built a takedown switch barrel in 25-06 ai, 30-06 ai, and 338-06ai with tie plan to get into reloading . Circumstances conspired against my hobby and it's a gun safe queen for now. I feel your pain!

I don't know if this helps but I use H1000 in 7mm Remington Mag and am working loads with US869 in 338 Lapua. Here in Canada. Seems reloaders here aren't using much 869 is still available on many shops. Just options.

Roll Tide is kinda like a term of endearment, like "hey bro" or "Jesus loves you too"....that kinda stuff...plus I thought the guy had an Alabama accent.?
Go Dawgs

There's always a tide rolling.
