I've shot about 60 rounds thru my 45-70 Ultra Hunter, 40 of those were Ruger loads with no issues. Also a several dozen each thru the 221, 6.5x55, 7x57, 243 and 6mm Ackley, hasn't been a problem for me.
That's with a button socket head bolt, if it has a regular socket head bolt, the results may be different, the button head is quite a bit lower profile and doesn't protrude from the stock like the standard socket head does.
