EL LOBO, My CJ-5 had a 350cu in Chevvy in it. Loved it for 19yrs, but sold it in a weak moment and it was in the boneyard in 2months. For fun I like 300gr Rem HP's out of my #3 45-70 at 2450fps. I also like 405's at 2150. A #3 only weighs 6.5# but I've shot numerous groups in the .3" range and these two loads plus a 330gr cast will group in an 1" at 100yds, mix or match as you desire. My original reason for the 50-110 post was to get a feel for the cartridge off the Marlin website and believe me that's where the only real interest lies for 50-110's in any great indicated desires. Whether they all get built will be another story.
