Home Forums Reloading Big Game Rifles 20" barrel, what powder??

Shot my new rifle yesterday, only shot factory loads to get sighted in and shoot a few groups for velocities. Was surprised the velocities were so slow. SO, looking for a SAFE, faster load with the 140 VLDH, Elite Hunters, ballistic tips, ELDX.

Rifle is a CORE Solutions, 6.5 Creedmoor, Lone Peak Titanium action, Proof Research 1-8 barrel, Trigger Tech Trigger, Manners EH1

Targets, first one is getting to 100yd zero

H-4350 seems to be THE powder for the Creedmore.

That's where I would start.

The same powder that gives the highest velocity in a long barrel will also do so in a short barrel.

The only concern would be if that particular rifle did or did not like it....

I'm getting 147s to around 2700+ in my 18" 6.5 with RL-26....worth looking into.

Way nice rifle BTW!!!

That's awesome velocity with a sbr, what's your load? I'm about to work up some loads with 140 and 147gr eld's in a 20' Tikka creed.

I clocked the new 20" Proof today. 42.5 gr H-4350 is running 2720 outta the new Bighorn

By and large, Buzz, this is fact...regardless of what the bullhorns on "that other site" like to shout.

I would start at 44 grains of it and work up from there to what your rifle likes or find pressure.

Ironically the 147 shot almost the exact same velocity in my 18" Barrett as it did in my wife's 20" Tikka CTR with the same powder charge.

There are instances where this is not true, but most people never shoot enough to find those exceptions.

Yes, that is correct. Sometimes powders leapfrog each other as barrel length changes. From what I've seen, though---using QL modeling, is that the switcheroos are never very significant in terms of how much velocity. Lots of guys are under the impression that barrel length is the most important consideration in selecting a powder, and that just is not the case. The general rule that "the same powder that gives the highest velocity in a long barrel will also do so in a short barrel" is a credible claim---with minor exceptions of little significance. That's why the disclaimer "by and large."

10-4 EVERYONE, i'll start with the good ole 42.4 H-4350, worked great in my Barrett.

Thanks for the compliment alaska !!

beautiful rig hutsman22. I have an Omega, sittin on my LGS shelf with my paid sticker on it !!!

I reckon you'll like it. I do...

Ha ha , I hear ya, I'm still in Ban Camp till 10/12 for something, not sure

Enjoy your absence.

I tried 43.0 RL-16 and 42.4 H4350
Both were accurate but this is because of the rifle. If I put time in , they would be tighter

4350 load was really too hot, stiff bolt and shiny case heads
RL 16 load was a "tad" warm but had good Vel. I'm going to tone both down a bit, see what happens. My BDC Turret is set for 140 gr @ 2625fps.

Is there any way to figure how much to lower these loads? 1 grain? how many FPS should this lower?

I know I should ladder test but I don't have the time or patients, I'm Old.

I'll post pictures later

Thanks

Can't give you FPS but 1 grain less on a slightly hot load should relieve the sticky bolt in a small case like the Creedmoor . I'd only load a few for a test though .
That's a great looking rifle - first class !!
Good shooting too .
