I used the fine 255gr JFN .38-55 load to take a nice Kentucky buck at sunrise yesterday. Shot was about 50 yards, full penetration and short death run by the buck. I saw it fall. It had proven to be very accurate in my Marlin chambered in .375 Win and I will continue to use this ammo for hunting in any of the four rifles I own in .375 Win.
Simply put, Great Stuff!

Shoots well in brand new Winchester 94 Trails End 38-55 rifle. Excellent and consitent accuracy with 3 boxes on the range. Using for this falls NY whitetail season. Feel very comfortable with this round for mule or whitetail.

I use this ammo in my winchester big bore 94. chambered for 375 winchester. I just dropped an 8 pointer in nh at 75 yards with open sights. I have never in my life seen a deer drop like that.......

I just fired a box of the jacketed, 255gr .38-55 through my model 1894 Winchester which by serial number was made in 1903. The accuracy was amazing....my groups were well under 3" at 50 yards at worst...with more practice and a with a scope (which I won't do), i'm certain I could do better. However the point of aim was 10-11" below where the rounds actually hit at lowest possible elevation (meaning the gun's new zero must be more than 100 yards). I will definitely buy more of this ammo. The larger .377 bullets DO make a difference; .375 bullets did not work in my rifle, and resulted in bullet tumble as noticed on hte targets
