Ramshot Magnum in .25-06

[filmjunkie4ever]

Was recently given a pound of Ramshot Magnum. The only thing of mine I have found that it might work out for is my trusty old quarter-bore.

Guy Miner has mentioned using Retumbo with 115 grain BTs for nearly 3200 fps in his 24" Remington tube. I see that 60.5 grains should get 3150 likewise. My .25-06 is a Remington ADL with a 24" barrel. I like the sound of those numbers!

Anyone using Ramshot Magnum and 115 grainers in their .25-06? If so, how did it do for you? Did you use standard or magnum primers?

Thanks -

Dale

No reason why it wouldn't work.
