Speaking of which, I see a used Ruger African in .375R for sale here in Canada,and I am curious, has anyone EVER REALLY found that these rifles will/do not cycle perfectly if ran hard and fast in the Ruger chambering?

Also, does anyone make/sell a 4+1 replacement mag box in steel for these? I think that I would love one so modded and in a nice Micky std. fill handle, to a all-in weight of 9ish lbs.
