Trouble finding Large Rifle Magnum

[black_hog_down]

I have Large Rifle. Can't find magnum.
Powder is H4895. 300 Ruger Compact Magnum.
I was hoping to work up some reduced recoil rounds with 125gr bullets.
Hornady manual does not list this powder and Hogdgon lists LRM.
Thoughts?

For standard large rifle primers, consider CCI 200s, Win LRPs, and CCI 34s which usually have the top of the line potency.

I got these.
If I use the WLR do adjust the load?
Anybody got a load that uses non magnum primer?

No not necessarily, start mid range between starting and max loads and go from there. The Winchester LRP primers should be fine.

"...Hodgdon lists LRM..." Somebody at Hodgdon is very confused. You'll note they show non-magnum cartridges like the .30-06 using H4895 with regular primers, but magnum named cartridges using H4895 as requiring magnum primers.
Magnum primers are about the powder used not the cartridge name. They are about igniting hard to light powders and extreme cold weather shooting. H4985 doesn't require magnum primers.
A 125 kind of defeats the purpose of an unbelted "magnum" cartridge too. However, I'd use the 135 grain listed on Hodgdon's site. Just not with a magnum primer.
