Just how "hard" is "hard"? I don't know, but if anyone wants to attack THAT problem, have at it. I believe a slick little device could be made to measure the resistance of a bullet to rifling.

Well why bother, Woodleigh know that steel jacketed solids are hard, hence why they are a fraction undersize and a bit tapered.

So that partly overcomes the hardness issue.

All I know is I have a DR, I work up a load for it, get it shooting, take it hunting and move onto the next DR or gun.
I'm just not into all this trying different powders, bullets etc etc. Prefer spending my money on other things once the gun is shooting.

Sometimes I wonder why more time isn't spent
shooting and hunting - or in some people's cases here,
going into business and making bullets !!!!! LOL
