Name Wes G:
I just had you install a conversion kit on my 700 ML. Haven't had a chance to shoot it yet. Can't wait.
Question: Groups before your conversion between 1.5 and 2"@ 100 with 105 gr BH 209 and Barnes 290 gr T-EZs. While that level of accuracy is fine for deer @ 100 yds, I am heading to NM for elk this fall and would like to improve my 5" groups @ 200. Thanks.
Try out the kit and see. Usually sealing up the breech improves accuracy as it makes pressures more consistent. What you are reporting is pretty good with any muzzleloader.
Thought I’d send you an update. Shot the conversion yesterday. My previous unmodified load was 110 gr (by volume) BH 209, CCI-M, 290 T-EZ in supplied sabots, averaging 5.25” @ 200 yds & 1919 fps (10’ instrumentation).
Since you recommended standard CCIs, I switched to those. Two shots with previous loads were 6.625” apart averaging 1863 fps. Bumped charge to 115 Black Horn 209 (by volume) with standard CCIs and shot a 3 shot group of 3.125” @ 1923 fps [all groups at 200 yds].
Thinking the slower velocity with the 110 gr load was due to the primer switch. Upping the powder got my velocity back with the standard CCI primers. That velocity appears to be the most accurate node from this barrel (having tried 105, 110, 115, and 120 gr by volume). I’m out of both powder and bullets currently, but after I resupply, I will shoot some more to verify repeat-ability. I may also try 110 gr by volume with the CCI-Ms to see how it does.
At any rate, I am thrilled with that group and that my glasses, nose, and thumb are no longer coated with soot and oil from the bolt. Thanks for your help and a great product.
That is great! Thanks for the kind words!
Remember that you can try the CCI-M's... they may stick in the nose and require a dry fire to remove... but usually that goes away at the higher charges you are using.
I always recommended standard CCI's as they have never stuck in the nose on me, but recently CCI changed from a copper colored primer to a Silver, and I don't have any experience with it yet. Regardless, you can use whatever primer you desire with our conversion, they just may require a dry fire to remove them.
Thanks for the update...
Here’s a pic. Trying not to get too excited until I get more powder and bullets to make sure that group is repeatable. The 3 shot group with 115 gr by volume was cleaned between shots.
