I have a 1895 Guide Gun and have been using some 405 LFN over 40gr of RE7. Had a bad problem with leading within just a few rounds. I backed off of the charge to 36gr and still have the problem.
I am beginning to think that the problem is the bullets are not large enough in diameter to fully engage the rifling (it has non Micro-Groove rifling). The bullets are sized .458 and I have read of barrels on these guns measuring .459 or .460.
I have never had occasion to slug a bore before and was hoping for some guidance. I have heard of using pure lead weights of the kind used for fishing and round balls but was wanting to get some info before attempting this on my gun.
Any pointers or recommendations would be appreciated
