Title kinda sums up the question. Is a 250gr RNFP bullet at Brinell 12 good for the .45 Colt[20" barrel]? 900-1,000 MV[tops!]
I'm thinking it's fine, but, I'd like some thought from some of our .45 Colt loaders/shooters on this. Thanks.

Excellent! I figured they'd be fine, but, a little assurance is always good. Thanks Al.

Can't see a problem if the bullet fit is right. I use my own alloy 2:2:96 that is around 11bhn. Not in 45 colt but have driven them to 2000fps with gas checks and 1600fps without with no issues.

Okay, in the interest of "no such thing as a stupid question," I have a few (maybe stupid) questions about Missouri Bullets.
I believe the bullet being discussed in this thread is this one:
http://missouribullet.com/details.php?p ... condary=14
As I understand it, basically all Missouri bullets makes are lead cast bullets. This appears to be a lead bullet coated with a baked on polymer that acts as a lubricant. Got that.
However, it appears that Missouri Bullets don't sell bullets that are "gas-checked," which was explained to me in another thread.
So, I guess the stupid question is: why do some lead bullets need to be gas-checked (or whatever the proper terminology is) and others (like these at Missouri Bullets) do not?

I'm going to hazard a guess here. Thinking gas checked lead bullets can tolerate more pressure and velocity so not to lead up a barrel or get "gas cutting"[?] from too high velocity. Never a dumb question here. Even old dogs can learn new tricks.
