I finally got the cylinder and barrel of my SS Redhawk 44 mag measured. I used #8 soft lead egg shaped fishing sinkers and a quality set of micrometers. I was shocked at how hard it was to drive the lead sinkers through the throats and even more so through the barrel.
Cylinder throats are .4315 and the barrel is .4295.
I plan on loading hard cast WFN 260 gr bullets with about 20 gr of 2400, mainly for feral hogs....big ones.
Off hand I would think I should order bullets in .430 or .431, however, I already have access to some quality hardcast WFN bullets that measure exactly .432. The .432 would be down to .4315 coming out of the cylinder throat into the barrel, so the bullet would be exactly 2/1000's over the bore.
I usually hear that there should be about a thousand's interference fit between the bullet and the barrel, but lately have also heard that tighter fit makes better accuracy.
Is .432 too big or has someone had expeience with this large a difference between bullet and barrel and found it to be OK?
I would actually prefer not to "blow anything up"!
