Anyone have experience with this round or conversion?
I have a Ruger no.1 in .458 Lott and read that it can be 'improved' by having a gunsmith straighten the chamber to create a small shoulder and slightly increase powder capacity.
Apparently velocity gain is somewhat nominal (50-100fps) and as far as I know factory ammo isn't available for this calibre but I handload so ammo isn't so much of a problem. Ultimately velocity increase is still velocity increase.
I should add that I predominantly use this rifle domestically with most satisfactory results in scrub at close range for feral animals and small vermin using light frangible rounds loaded as fast as I can reasonably get them.
