I just picked up a few 200 and 225gr barnes .451 XPB bullets to load in my 460's. I also have some 185's for maybe reduced loads depending on the diameter they come out to on the MIC. I see people mic the .451 at .450.

Has anyone had any fouling problems with these? Not sure if I want to push them out of the 460 or use them for 45 acp.

I have shot hundreds of Barnes XPBs in 200, 225, 250, 275 from my 460s with no issues.

Typically I use #9 with these but have also used N110, H110, 2400, and Enforcer.
H110 will produce fastest velocity, N110 is the cleanest shooting, and #9 produced the smallest groups with the 200 grain XPB, that said the difference in each criteria a pretty small.

I use a case full of Trailboss under 250 XPB for use out of my ES for finishing pigs while hunting with dogs.

As far as copper fouling - its no more than jacketed bullets.

How did I know you would be the one to reply, I was going to message you but didn't want to bother you again haha... As soon as I stop working I am going to open up a welcome thread with the few smiths I have. Probably Tuesday ill be able to take a few pictures.

I will probably try some trailboss, cfe pistol and I keep seeing H110. So I will have to pick that up. I was initially going to run the 45 lc ammo I have but I would rather not foul the cylinder like that.

CFE is to fast - possible to double charge also.
