Hey all,
Looking for some information. I have the above mentioned rifle and I'm looking for the twist rate. I've seen some information about the 840/340/325 in 222 and 22 Hornet that suggests a 1:16 twist, but so far, I can't find anything on the 30-30. I had the idea to load some Hornady SST's for it, thinking maybe I could stretch the range a bit. The 150 grain bullets were long enough that they didn't work in the magazine, so I dropped back to a 125 grain load. At 50 yards, you can almost stack the bullets in the hole, but move out to 100 yards and it sprays them all over the target. I started with 32 grains of Accurate 2520 (because that's what I had), then loaded 10 more rounds at 33.5 grains. There was little difference in the way they shot. The overall length of the 125 grain SST is about the same as a 170 grain flat nose, but all of the mass is farther back on the SST's. The guy that runs the range where I was shooting suggested that the twist rate was not sufficient to stabilize the 125 grain short bullets. Any thoughts...?
