I've done a lot of sampling to see what my 1894 "likes" best. I've fed it Winchester 240 gr, Winchester Partition Gold 250 gr, Winchester Platinum Tip 250 gr, American Eagle 240 gr, Remingtion 240 gr, Hornady 240 gr, and Black Hills 240 & 300 gr. So, far it seems to do best with the Black Hills 240 gr(although, this ammo is quite "dirty"). I've got some Fiocchi 240 gr, Magtech 240 gr, and Gold Dot 240 gr that I will be testing on my next trip to the range. But, it seems that the best I can get out of my 1894 is about 2+ inch groups at 50 yds. It took me a year to find my 1894 (it seems that demand exceeds production) and in the interim I had purchased a Henry Big Boy in .44 mag. The Henry likes the Winchester Partition Gold 250 gr the best (1" groups at 50 yds), but out performs the Marlin with any given ammo. I suspect that the trigger is the factor in this performance difference. The Henry has a clean, crisp trigger pull with no "slop" ... just increase pressure until the gun goes bang. Whereas the Marlin's trigger is a bit sloppy and has some creep making consistant firing difficult. But, I'm not positive this is the issue. Have any of you done in trigger work on your 1894's or otherwise been able to improve performance?
