    Posted: December 16 2016 at 10:03am
Gents, I have just bought a batch of South African made 230 gr CMJ  bullets for my 1911 pistol. 
Usually I have load 230 gr FMJ bullets. Is there any need to reduce the load/velocity for the CMJ type? 
My current load is 0,23 grammes of BA10 (Vectan) (Max load is 0,26g)

Thanks in advance, Zed.

I have shot FMJ and plated with no noticeable difference. (Xtreme bullets) The manufacturer said they were good for 1100fps+ and that shouldn't be a problem with 45acp. They did say to check the target and if you see several small holes around the impact point you were experiencing flaking and needed to slow it down. Be careful with the crimp because you can dent the bullet.
Can you contact the manufacturer and see what they suggest for an upper limit?

Not sure where your load falls, the manufacturer I was using recommended mid jacketed levels as max.

Are the CMJs plated or fully jacketed?

They are copper plated; but the copper is all over. No lead visible. They are South African made and they appear to be very nicely made. I have always used the standard FMJ copper jacket type 230 grains until now. My current load is mid range for BA10 powder. But it is a fast powder, so may drop it back a bit.
I'll hopefully get some loaded up over Christmas; so I'll let you know how it goes.

Total Metal Jackets (TMJ's) are what I use in my Glock 22/.40 cal. Clean shooting, excellent plinking round. I buy the Winchester 'WinClean' product.

OK I've always heard to load plated as high end lead as a maximum.

So I got to try out the new CMJ 230 grain bullets. They shoot well; similar to the FMJ230 grain and recoil is similar.
 However there is one thing that is odd! The cases are coming out blackened by powder on one side (outside). I have never had that happen with the FMJ bullets. 
The bullets were shot during colder than normal weather, it was between 0 and 2°C on Saturday. Also the temperature when loading was cold, at around 2-3°C. 
The powder and charge weight remain similar 0,22 grammes of BA10. I've been using this load and powder for many years without issue. I made no adjustment to the loading rig.
So what could cause the blackened residue on the cases?

Gas is passing the case mouth as it hasn't expanded fully to 100% seal the chamber would be my guess.

Too light a load doesn't expand the case to chamber dimensions ; increasing powder load should solve the problem. I shoot Frontier CMJ's in 230 RN/N320/5.0 and 200 FP/N320/5.3. As a guideline, CMJs are treated similar to classic FMJs.

I will up the load slightly to test. I was a little surprised as I have never seen this before with my .45 and my reloads. On the left; a used (uncleaned) case from my last load using 230 grain FMJ and on the right is the used case with the 230 grain CMJ bullets.

All 50 rounds looked the same. The load was 0.22 grammes of BA10 (Vectan) with both lots. The only other difference being ambient temperature.
The cases have been used many times prior to these loads.

the temperature can cause this , i have had issues with my light cowboy loads at cold winter shoots , not enough pressure to swell the case ,

Thanks for the replies Gent's.
I'll have to load up some test rounds and see how it turns out.

Well my .45 colt rounds look like the one on the right after firing them.... guess I should bump my charge up in them a bit !!!

thats exactly what my 45 colt cowboy rounds look like - they are 200 grn cast bullets at 600-650fps and they do not swell the case enough to trap the full gas charge , positive side the brass lasts a long time - little to no stretch in any direction , just gotta tumble them a bit more , 

had no issue getting them clean and almost no resizing required - just finished the final 500 last night , im set for about three years of matches at this point , both rifle/pistol and shotgun , i only had five bad cases this time around and have only bought 500 new cases since 2003 , 

these are far from what you probably shoot - i am restricted by rules of the game for fps , im also shooting big steel targets at close range so accuracy is not the issue for me , i want slow but positive , accuracy takes care of itself in my hold , im all about time on target ,
