300 Whisper subsonic rounds with SR Magnum primers?

[coldbeerchief]

Anyone use the magnum primers for their loads?

I have a boatload of Wolf SRMs I'd like to use up

I have several thousand Wolf SR mag primer and they work great- I have not noticed any real difference using them

Have tried them to see how much difference there is between reg. mag. and spp. All worked real well. Had to slightly lower load with 110 or 296, but they were consistantly all right...

As noted above - there will not be that much difference. Maybe have to drop the powder a little that's all.

I was told by the vendor that the Wolf magnum SR primers are not any hotter, the only difference is the thickness of the cups. Basically, the magnum primers replicate the harder "arsenal" military primers - I use them in all my AR loads.

Yep- thats my understanding
