Marlin 1895 Accuracy: Last Desperate Attempts

[MGySgt]

There is one problem with the 1895 that I have fixed on mine. The screw at the end of the magazine tube was actually warping the tube there by putting downward pressure on the barrel.
I took a steel washer and thinned it down so it would just fit in the place at the end of the magazine tube. This relieved the pressure on the barrel and my groups shrunk to sub MOA at 100.
check your pressure at there.
By the way my 430 gr FP may by Mountain Molds is a verry stout load.

I have a 1978 Marlin 1894C .357 Mag Carbine. I had trouble finding an accurate cast load as the gun is finicky with cast bullets. My goal was a load that would hit a 2.5” wide object at 150 yards consistently. 2 years ago I succeeded. I used a Lee 158 RNF bullet that casts out at .360” sized to .359”---the load is 6.0 of Universal in a .357 Magnum case. Obviously it is best to shoot on a calm day as the BC of the bullet and lower velocity will be adversely affected by any substantial wind.
