Large rifle magnum primers

I use LRM primers in my 308 when using BLC2 and 748. I do not reduce the charge.

I found that when using LR primers with those powders a large flame could be seen and significantly reduced fps. When stepping up to the LRM primers, the flame was gone and increased fps.

I do not use those powders for my 308 anymore as the Varget is so much better in my rifle.
 
Yes you can use them but I would reduce the load by 10% and work it back up.
