6CM testing Results
- Thread starter joesr

My Krieger's give me a lot of speed so with that being said I will stick with Krieger, oh yeah, they also shoot great. My 27" is shooting a 115 Dtac 3153 fps with a load of 48.7 grs. of H-1000. I was shooting 49 grs. of H-1000 at 3225 fps backed it down 3 tenths and shrunk the vertical at 1000 yards by 2 inches. For both loads my dope worked out so I would have to believe the chrono. The same goes for my 30" Krieger 49 grs. of H-1000 is fast and accurate. Very accurate, either 1 of these barrels will shoot in the 1's, that is tenth of an inch. 5 shot groups... I WILL PIMP THE 6CM...

Actually with the "official" results, I think Joe may move up to 4th overall. I believe Tubb may not have been qualified for an official placing due to his use of optics. That's my understanding, but I could be wrong. In any case Joe's an excellent shooter either way (and so is Carl). The 6mm's really do shine at XTC (Carl with the 6mm HAGAR, Tubb with the 6XC and Joe with his 6CM).

Give it a while and I will have some info that may help you. Have a build with the very intent your looking at in process right now. 6 CM in a TAC set up, 26" barrel with a suppressor. Only thing with the 115's in a mag fed rifle is there may be some seating depth problems but we will see.tmr said:

Paul,
from what what I've seen on a couple rifles chambered in 6CM, (one is fellow Colorado forum member Hoser's rifle) H1000 is the go to powder. Also worth noting, shot a steel match with Hoser a couple months ago where he was shooting fire-forming loads, he shot very well. It's good to see this stuff 1st hand.
Should have my Bighorn/Brux chambered in 6CM by the end of next week, I'll post the results.

Paul,
I have been testing N-165 recently. Tested from 46.0 to 49.0 with no pressure signs. Settled on 47.5 as that gave the best accuracy. All loads were tested with Berger 105 VLD, Win. brass, and Wolf LR primers. No chrono data yet but it looks promising. Will get to test at 600 yards Wed.
Guys,
Thanks very much for the replies. I also have a Bighorn action on order and am planning my next build. Sounds like a great round to consider. ;D

Have 300rds on my Bighorn/Brux, 28"/7.8 twist. Chambered by Chad Dixon.
Fire-formed load, 47/H1000, BR2, 107SMK's. FF velocity 3040.
Worked up loads with Dtacs/.015 jump. 47-49 H1000, .5 increments. Going with 47.5, 10 shots, 3062fps, ES 17, SD 8.
Shot a steel match at Raton yesterday, posted my best score ;D Can't wait to shoot another match with it!

I think 47.5 gr of H1000 is right in there. Personally I always found that the 47 - 48 gr range with H1000 offered the best day to day consistency and accuracy in that cartridge. Every time I have gone higher in charge weights it seemed like I was getting closer to being "on the ragged edge" - - got the raw velocity, but day to day accuracy and/or consistency became more difficult. It's the same with a lot of cartridges, you can always run things hotter, but what are the compromises you are making to do that? I like to have loads that I don't have to even think about, they're "good to go" all the time (i.e. when it's hot out, when it's cold out, when there's high humidity, when there's low humidity, if the barrels cool and clean or hot and dirty, in higher altitude, at sea level) - - it's about hitting where you are aiming every time.

u need to compare ballistics of 115 dtac versus 105 hybrid .seems 105 is as good + added velocity !!
