Hello,
On Sunday I tried some plain base plinking loads in a Savage Enfield No4 Mk1* with two groove barrel and also a Mosin Nagant M91/30.
Basic Load Data:
9gr Trail Boss
185gr Lee C312-185-1R bullet without gas check.
Lee Liquid Alox
Velocity of load averaged 1190fps.
My alloy is soft, does not lead the bore when used with a gas check and lubed with Lee Liquid Alox. Groups about 3 inches or so at 50 yard with the Enfield and 18gr of 2400. These are moving about 1500fps which is probably too fast for the alloy. Barrel does not lead and all looks good other than the groups.
The Mosin Nagant did well with a gas checked version and 16gr of 2400. No leading, shot very low at 50 yards. Not sure what group was, as it missed target and backing.
The above was a bit of background.
Now, when using 9gr of Trail Boss and the same bullet without gas checks, the bullets would actually melt in the barrel and hit the target with a splat. Closest thing I can say is the bullet looked like bird crap hitting the ground. Just splattered.
Now, I also had some Lee C312-155-1R bullets sized down to .309 for the Swiss K31. I had done these awhile back and gas checked the bullets. However, we were testing Trail Boss so I used 9gr of Trail Boss under these 155gr bullets in my K31. These did not go splat, did not lead the bore, and grouped fairly nice at 50yds.
I have no photos of the targets that the Enfield and Mosin Nagant had shot as as they all missed the target. I do have photos of the K31 targets.
Questions:
1. Why would my alloy melt in the barrel? Is it possibly I have an alloy very high in tin? I was basically shooting liquid alloy out the barrel.
2. Would paper patching correct this problem or should I just stick with my gas checks until I am out of his alloy?
Some Stats on the barrels:
Enfield .304 X .315: Bullet Sized to .3145
Mosin Nagant .301 X . 313: Bullet sized to .3145
K31 not known at this time.
Comments and Suggestions welcome.
Thanks,
