I was shooting my Mannlicher with a Lee 6.5 torpedo bullet and a Rcbs 140 grain 6.5 bullet. The lube was Lyman Molly. The barrel leaded up about 4 inches from the muzzle, it was so bad it covered the lands and I could not get a large rod passed it. The barrel slugged at .269-.270 and the bullets were .266 and .269, the gas check was sized to .269, the nose of both were vedry slightly engraved. the velocity should have been around 1500 fps. I have to cut the lead out, I have used 4 6.5 and 270 brushes.
What seems to be the problem. I was using 16- 18 gr of 5477. I thank you for suggestions.
