I’m .015 off in my cm
.010 off in my BR
My buddy is .010 off in his BR
I’d run your load development just touching and find the speed/charge your happy with then seat .005 back at a time until you find the group you like.
I find my charge then load 40-50 touching and use a lee hand die in the field for seat test.
The 6cm is one of the easiest cartridges to load for I’ve shot...
H4350
CCI450
105 hybrid
Peterson brass
If it won’t shoot with the above something is wrong.
I usually load them up at home .005 increments out to .050” I’m hoping for a little luck here, with my 6.5 creedmoor there was so much info available I did my powder charge testing at .020” off because everyone was jumping the 140eld .020-.030 and I am still using that length after a seating depth test I am hoping for the same thing with the 105hybrid because the 108eld wouldn’t shoot under 3/4” at 100yd for me after more rounds of testing than I care to admit
I will be using 105 hybrid
Lapua brass
Fed 205m
H4350
Did you Chrono them?Thanks for the info guys shot yesterday @.01off , 40.6 gns h4350 gave me 1/2” at 200yds for 5 shots
20 shots to find the load didn’t even bother to shoot the remainder of the charge weight test
Just curious what brass did you use? Seems like low charge weight for the 6mm.Thanks for the info guys shot yesterday @.01off , 40.6 gns h4350 gave me 1/2” at 200yds for 5 shots

Damn well those are pretty good numbers.
I’m running 41.8 for of h4350 in starline brass. Velocity is 3031.
24, just a factory rpr
Ah that’s make since. Quite a bit more barrel there.
Wow you’ve got a fast barrel. I’m running 105’s with 42.2 h4350 and I’m at 3130.... nothing wrong with less powder and more speed!! Just a little jealous ?
I stopped worrying about barrel life 20 barrels ago it’s all part of the game...like you say speed is not free and I don’t mind paying for it.
Exactly!! Nothing is free and I figured it’s a better vice than sitting at the bar so might as well shoot while the eyes are sharp.
Agree 100%...as far as the eyes go...I just keep buying bigger scopes lol!
Ha when in doubt buy big!!! 15 years ago a 50mm scope was considered a huble telescope.
What is everyone find the 105 hybrid likes for jump in there creed I’m giving up on the 108eld after way way too many rounds trying to make it work and I’m looking for an expedient development with the 105 if possible
mine is a 1-7.5 Hawk HillWhat twist rate barrel for the 110's?
Did some initial barrel break in & load development on a new 6mm CM
26” 1-7.5” Bartlein
Peterson SRP Virgin
CCIBR4
Berger 105 Hybrids .015” Jump
H4350
Was hoping to find something promising at around 3000 FPS but started my ladder test about a grain too high.
40.6 - 42.2 all printed right on top of each other at 300 yards.
40.8 shot 3049 Avg, 4.2SD/9ES/.4MOA
41.0 shit 3064 Avg, 5.9SD/17ES/.4MOA
Will load and probably stick with 40.9 at 3055 FPS-ish as long as the accuracy is there and ES isn’t too high.
I ended up chasing speed and going with 42.2gr H4350 with great accuracy. Averaging 3230 out of my Havak PH1... after these next 100 rounds I’m going to see what the lower node is with 4350. I’m guessing around 3030 as that’s what the Hornady 108eldm and I’m blown away by the accuracy from factory while also having SD in the low teens.
@Wheres-Waldo I Would love to hear what you settle on for your final load.
I’m still running mine over 3200...648 rounds and dying by the round...hoping to get 2 more matches out of this barrel

What’s wrong with your Magnito speed? Mine has run spot on. For velocity and plugged in to a ballistic calculator. Run out to 1200 yards on multiple rifles.I’d much rather back off to 3000 FPS & have a barrel that will likely last at least 1750 rounds.
Learn to read wind better than the next guy can cram 50 grains of powder in a case and you’ll be happier.
Was using a Magnetospeed on a spigot mount and a Labradar side by side for the first 50 rounds or so before I was ready to throw the Magnetospeed in the trash, I’m 100% selling that thing.
Ladder testing at 300...

Pretty much pointless for finding vertical nodes...

Whoa that’s quick, 648?!? And already dying? I’m definitely backing off then. Don’t need the extra speed just wanted to see the potential of the cartridge (which is badass). I’d love to get 1500 rounds out of the barrel, not looking good now lol
I'm guessing no ones speed checking at the matchs, and what powder are you running that eating the throat so quickly
