I have a question foryouhandloaders. I have always used Winchester large rifle magnum primers for my 308, 30-06 and 300WSM. I have always had good sucess with them, but I can't find any around my area MPLS
If I switch to another kind like CCI will it affect accuracy? And will they work in cold weather?
Thx

My rule of thumb is only use a magnum primer if you need it. So I would defiately drop down to a WLR or Fed 210 for the 308 and 30-06. I have had very poor luck with mid burning powders like 4064 and varget and even 4350 with mag primers. Powders like RL25 and H1000, and Retumbo, I require a magnum primer.

Have you checked with Johnboy's shop....the Gunstop?
John can tell you where to get them if they're available.

See his website www.gunstop.com for more info

Generally I concurr with this.....using a LR primer should have no negative consequences at all.

Thx, I did call the Gunstop rightbefore Christmas and I was able to pick up a 1000. Also after doing some research I found that magnum primersare recomended for ball powder in cold weather.

Winchester is certainly a fine primer. . .I use them exclusively for pistol. For rifle, I prefer Federal. They are generally considered more powerful and more consistent. For my AR, I use CCI. I would rather use CCI #41 military, but they are not available locally.

Basically primers are interchangable, but I would load a couple and reconfirm. Chances are you may need to work up a new powder charge for ideal accuracy and velocity.

Be very carefull changeing primers in a ginen load. Especially in a near maxium load as the primer can add a couple thousand psi. to that load.
