I found an abundance of this at a small outdoor store.
I've never used it , curious if anyone uses it.
And what calibers would it be great in?
I did look at the load data but still curious.
I’m using it for a 6.5-06 with 140s. I have a friend that’s using it in a 338 rum with great success
My Sisk 280Rem us a “one-hole wonder” with RS Magnum.
Have used Magnum in quite a few cartridges with excellent results, including the .240 Weatherby, .257 Roberts with 120-grain bullets, .25-06 (again with 120s), .257 Weatherby with 100-120 grainers, 6.5x55 with 140s, .264 Winchester with 120-140s, .270 Weatherby, various 7mms with heavier bullets from the .280 AI on up, .300 Winchester and Weatherby Magnums with 200s. It also worked great with 400-410 grain bullets in my .416 Rigby.
Tried it in my .257 Roberts with 115 Partitions (at Mule Deer's suggestion - thanks) and it shot wonderfully. Fast too. I'll have to give that 6.5x55 with 140s a try that he mentioned above. And maybe the .280 with 160s.

I use it with 139 and 142 grain bullets in my 6.5 PRC. Good velocity and great accuracy.
Provided great accuracy and speed with 150gr Interlocks in two 270WCF.
Thanks for the information, I'll pick up a few pounds .
