I'm a newbie here, so please excuse me if this has already been covered. Just tried a new load that came highly recommended. New .223 primed brass (WIN) with 25.0 gr RL-15, under a 75gr. Hornady BTHP Match bullet, loaded to max magazine length (2.250) OAL. I chrono'd five rounds on my Ohler 35P, and had an avg. vel. of 2793fps out of the 24" S/S Wilson 1:9 twist bbl. on my Colt Elite CAR-3. Accuracy was .75"@ 100yds. The real problem is that this thing leaves a WHOLE LOT of powder residue (real dark black) both in the barrel, but also some on the fired cases and in the chamber. What am I doing wrong? Maybe trying this powder is it? Has anyone else out there experienced this ? I've used Varget and H4895 and never experienced this before now!
EWO- That is the load I used for 75gr Hornadies, 77gr SMK's, and currently use for 69gr SMK's, in my MT HBAR 1-7 twist, I have not seen the fouling you talk about. I also use 24.5 grains under the 80gr SMK's same on the fouling, not there.
Not much help just letting you know!
Mike

I also have one of the colt elite rifles and w/ a 1:9 twist 75gr seems to be a bit much for mine to shoot. 69grSMK's shoot mid 3's &4's 5 shot groups. Mine likes 25.2gr of 748 winchester ball. It will spit the 69's out at about 3000fps What range are you shooting. I was just wondering why you would want to shoot the heavier bullet. Wind drift perhaps? Those are bad ass rifles aren't they. They started out to be a limited production run but that idea soon changed. I know of only 1 other person with one of those. Now I know 2. Pleased to meet you.
