RE: What primers to use in .308 loadings?
 

I loaded up .308Win just to kill clay pigeons on the berm at 200yds. Using Winchester standard large rifle primers, I got the best accuracy results from 39.5gr of IMR4064, pushing a 168gr AMax. Four shot groups were consistantly touching eachother at 200yds. Working up the propellant load the groups were good until I went beyone 40.9gr of IMR4064, at which point the groups began to open up. I have found no problems using Winchester primers. The rifle is a Savage Model 10LE with McMillan stock and 26" bbl. I fired three shot groups at spaced intervals, allowing the bbl to cool for 20mins between groups.

I dont really care for cci much, the gun stores around here really dont carry much anything but winchester and federal. I decided to use federal 210 primers, Im thinkin i will stick with them.

You know a good solid reliable dyanamic load, primers will not make too much difference. I can take my 308 load and put CCI's or Fed 210's and get pretty much same results. I can also move my COL from 2.77" to 2.83" and not see too much a difference in groups. I could shoot it in 20 degrees or 80 degrees. All would be under 1.5" at 100 yards. Thats what I love about a 308win. Not too many calibers I have seen can accomplish this.

Winchester primers are the one exception.

Yep winchester primers hehe I figured out the other day a winchester small pistol primer works just as good in my 357 mag loads as a federal small pistol magnum primer.

If you ever happen to see a article in Precision shooter 1998, I believe about primers, take a read. It actally says Winchester mags primers are hottest by far, but WLR primers are not as powerful in pressure than a 210 federal. I was surprised. Been years since I looked at it.
