Home Forums Reloading Big Game Rifles Effects of Primer change.

I have only been reloading for about a year or so, I primarily load for my 700 in 30-06.

Most people have good luck with the 4350's, but mine has shot the IMR 4064 much better, HOWEVER most people seem to load their 4350 loads with fed primers, I had done all my 4350 loading with Remington and CCI.

Now that I have some Fed 210s, should I revisit the 4350's, or does the manufacture of the primer not matter so much as to try again?

Thank you.

Once I find a load I like for accuracy I start changing primers. One can never tell what a different primer will do. And it is not brand specific.

You never know until you try it. I've seen it make a difference sometimes and sometimes it doesn't.

A buddy once mistakenly loaded either Fed or Win primers in his pet 22-250 load. Rifle shot about an inch or slightly better. With the CCIs he normally uses, it's always 3 shots touching at 100yds and he has a target where it once touched 3 shots at 300yds.

Barkoff, primer can make a difference.

On load in my .338 will consistanty shoot sub-MOA with Winchester Magnum primers, but 3 MOA with Fed 215's.

My pet load in my STW is sub 1/2 MOA with Fed215's but not with any other primer I've tried. I haven't tried the Rem 9 1/2's yet with it, but plan to next spring.

Thanks Gents, I'm going to revisit the 4350's with the fed, since I already have a couple of pounds.

I've been loading a little over 20 years. I started with Winchester LRs for larger rifles and Remington 7&1/2s for my 223s and have pretty much stuck with them. I've read enough about the difference primer change can sometimes make that I believe it can but since I can usually get MOA or better with what I already have I leave well enough alone.

I get the best accuracy with IMR 4064 and 150s in my 30-06 but 4350 does better with 180s.

I too have found that primers can make all the difference in a rifle.
I used to always use WLRM in my 7 mag and when I decided to build my first custom it wouldn't even come close to shooting MOA. On a whim a buddy gave me some federal 215M, and boy howdy, that made all the difference in the world. Settled on Retumbo powder with 180 vld's and 215M primers touching the lands. If I do my part it'll print them I side of 1/2 Moa too!!
