2023年12月15日 · As has been noted, .308 Win Small Rifle Primer (SRP) or "Palma" brass uses small rifle primers, standard .308 Win brass uses large rifle primers (LRP). You need to know which type of brass you are using and order the appropriate primer for it.

2021年3月20日 · Woofie, Measure the diameter of the Ready primers and compare to old white box or blue box primers. Let us know which color box they appear to equal.

2024年5月13日 · It always comes back to action / firing pin with SR primers allied to loads / pressures. A good custom action with a small diameter firing pin and excellent small fit in its bolt face aperture will run maximum pressure loads without cratering or 'blanking'; the worst of the Savages / Remington 700s will see serious cratering with these primers with modest loads and …

2015年3月10日 · I've tried CCI, Winchester, Remington, and Federal primers. I've had my best success in large rifle with Federal 210 and 210 match primers with: Varget & IMR 4895 in the 308, and Varget & IMR 4350 in the 243. For small rifle (223), the Federal 205 match give me very consistent results.

2020年2月17日 · You have lots of higher priorities than small primers. Sort out those issues with your existing brass.

There are some commercial primers that would pass these tests, but not all of them. The #41 primers are certainly capable of AR15 loads and worth a try on 300 BO.

2019年7月20日 · You really just have to test them. The 41s are just magnum primers with durable cups to prevent slam fires in military arms. As a general rule, using the least energetic primer that will work is advised. But so much of the ignition process is unknown to us that pragmatically you need to test if you want to sort them out. The powder used matters.

2024年11月29日 · Ran a ton of these in my CMP modern military rifle. Did have an occasional hiccup but cant say if it was the primer or the bolt carrier. Sometimes it fired on the second strike. Think they performed as well as can be expected.

2014年10月19日 · The Winchester WLR (fairly recent and the package marked 'for standard rifle loads' proved one of the 'hotter' models, and as a result produced one of the largest velocity spreads in the tests. Whilst most models produced 15-shot average MVs in the 2,780s, the WLR increased it to 2,806 fps average, an ~20 fps increase.
