That's only like 75k PSI, what could go wrong?
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.

You posted your rifle and load data. To get 3200+ FPS velocity with a 28" barrel and those components you need to run between 68k and 75k PSI of chamber pressure. You're close to proof load pressure.
Now I'm going to have to measure what I've lost, I'm running h4350 and right around 3100 with 300ish rounds through the barrellocal matches mostly...H4350...ive lost .025 off the lands in 648 rounds.
At 75k I’d be having brass issues...6 loads tight pockets and I have NO hard lift sticky bolt or any other issues.
I’m not saying your wrong but without pressure trace equipment we do not know where pressures are.
You're kidding yourself. You don't get velocity without pressure. Your chronograph is clearly telling you you're majorly over P Max. Whether your brass is blowing out or not is irrelevant.

This IS my first Creedmoor, so I don’t know it’s nuances and how barrels behave over their life and what velocity/barrel life actually is.
Staying with 40.4 gn H4350/105 Hybrid @ 3035 FPS
AVG .50 MOA at 300, not sure if I should strive for more accuracy but I’m not a 1/2MOA positional shooter & would like to actually start practicing with this platform instead of getting sucked into perpetual load development.
ES & SD are a bit high, but I’m fine with it unless I start dropping hits out of the top/bottom at distance.

I chronographed each 5 rnd group posted above & analyzed them as individual groups.
9.1/20
6/15
9.8/22
Does anyone have experience running a really slow 6creed? Im talking 2850 range. I have one as a backup rifle to my 6br and was thinking about dropping speed to match that gun and also get some kind of barrel life out of the gun.
I have very good results with reloaded 26 and 105 hybridHave you tried reloder 26
I have a 6cm rifle currently but shoot factory loads. If I want to get into reloading, is this a good first one to jump into?
H4350 is my powder as well although I’m running 115 dtacs at about 2900 in a 19” barrel.
I don’t see why not. You have brass already. Pick up some H4350, some primers and the bullets you wanna use. The most popular are 105 Berger Hybrids.
Factory rifle or custom?
It’s a custom. Green Mountain blank from Keystone.
One concern I have is that I’ll be learning on a round that is quicker to burn out barrels. How steep is the learning curve in general (even though this isn’t reloading 101 thread)?
What was the temp out with the H4350, I running 41.8 and only was getting 3080 out of 105 hybrids but I did the work up at like 50 degreesFinally chrono’d my two loads with the 108’s
40.6 of RL16 gets me 3039 w/3.6SD
41.5 of H4350 get me 3120 w/ 5.7 SD
Only 5 shots, but It’ll do
Think I’ll go through these remain jugs of RL16, first.

Try running some varget. I ended up running 38gr of varget in alpha brass. I chopped down a barrel to 18". Velocity was 3030 with a 105 amax. Had some old bullets laying around. Good for smoking coyotesForgot to mention this. But my suppressor seems to heat up really fast when shooting H4350 in a 19” barrel. Could this be due to slower burning powder burning in the can instead of the barrel.
That’s pretty wicked for a short barrelTry running some varget. I ended up running 38gr of varget in alpha brass. I chopped down a barrel to 18". Velocity was 3030 with a 105 amax. Had some old bullets laying around. Good for smoking coyotes
I've gone through one load development with the Nosler 115 grainers... Found a node at ~2900fps pretty easily and confirmed trajecotry at 1054 yards using G7 BC 0.310. I didn't have any issues, so I bought some more. I"m using 38.6 grains of H4350 and jumping 0.010". I also loaded up single rounds with greater powder charges, my rifle accepted 1.2 grains over book max before showing pressure signs.Anybody try Nosler 115 grain Rdf in 6 creed b.c. is .637 i think? Or do they shoot like $#@!

That's good velocity for a 24 inch barrel. my Barrel is 28 inch 7 twistThe 115 rdf prime ammo is shooting great out of my .135 freebore 6 creedmoor. 1/2 moa groups. Getting 3030 FPS our of a 24” 1:7.5 twist barrel. Looking forward to hand loading some 115 RDFs. Actually shot this elk at 360 yards today with the 115.View attachment 7206068
Yeah I was really surprised with the velocity from factory ammo. The barrel has always been fast. I’ll be sad when it dies, I am at around 1000+ rounds.That's good velocity for a 24 inch barrel. my Barrel is 28 inch 7 twist
