Are you talking about the green bullets? If so, just be cautious- Paul ran some 45 and they leaded badly. I think the guy put a Brinell on them of about 10, which is really low, and 45 just doesn't ramp enough pressure to spread that kind of softness out. 40 does though, so you should be alright, just keep a watch.
An update on this TJ.
I have been checking these bullets out and talking with Jerry (who make them) and I did have problems with leading in the gun I have been building I shot some of my usual bullets in it and also got some leading but not near as bad. I have a forcing cone issue that I will address and retest. I'm going to shoot some out of my main gun that never has leaded before and see how that works out.
I spoke with Jerry at the match Sat. and he said he made a error in the process of putting the coating on the first batch.(the one I used).
So it may have been a combo of my gun and his first batch error.
This is the same coating that Bayou bullets uses and it gets good reviews from other shooters.
I'm still testing these bullets so I hope they work out as their are many benefits to the coated bullets.
