mk23 Posted October 13, 2008 Share Posted October 13, 2008 Is there a minimum Dram equialent I should be looking for in bulk winchester ammo to get my M1S90 to run 100%? It's fully broken in, but still hiccups once in a while with some of the wally world bulk packs. Mostly looking for cheap stuff to shoot for fun.

mk23 Posted October 13, 2008 Author Share Posted October 13, 2008 Some more info I have 2 M1S90 and M3T. My first M1 is an old HK marked I have had for 10 years or more. It has always eaten everything. But the last couple of boxes I bought from wally world were winchester ones, 3 dram 1 1/8 #8 shot and none of the 3 guns want to cycle it. Just too weak? Both of the recoil assemblies on the M1s were cleaned and oiled. Quote Link to comment Share on other sites More sharing options...
