Matt's bullets and old cast bullets

[sniper]

I don't cast any more, but I have few hundred 150gr. bullets left from my last casting session from the RCBS 38150K mould. I tried to come as close as I could to Lyman #2 alloy when they were cast, but how much has that likely to have changed over the years? Is there any way to tell, without purchasing a hardness tester...not in the cards...?

I have bought some Matt's Bullets 160 gr. RNFP bullets to test, and had them sized to my cylinder throats... .358. Matt's standard size for the projectile is .359. Can I just order the .359, and don't worry, be Happy? Will the nominal ~ .001 over cylinder diameter be a factor at all, or should I just run them through my .358 resizer and relube with BLL when I get some more?
Thanks!:)

If it will fit in the cylinder, I shoot em.

Far too many shooter worry about BHN, if they fit, just load them up.
Over size is better than under sized going thru cyl throats. You should be fine @ 0.359".

In my S&W revolvers I tried .359" boolits, but had to work to get them in the cylinder. Not hard, but they did not drop in, either. .358" drops in and works fine.
