After the move out to Washington State last fall, I stashed a whole bunch of totes in a storage unit while I sorted out living arrangements and such.

I was going through some of the totes today, and discover a treasure chest of forgotten reloading goodies. Among the ample booty, was two unopened 500 count boxes of Hornady 6mm 105 HPBTs, a nearly full 8lb jug of RE23, a brick of CCI 200 LR primers. That’s 1000 unassembled rounds for the 6 Creed.

Anyhoo..... I’m hoping someone can run a QL for me, on the following parameters:

6mm Creedmoor
2.80” Max COAL
20”, 1-8” twist barrel
105 Hornady HPBT
Reloader 23
62k max PSI

Thank you in advance...

PS.... Along with all that stuff, was: 5+ lbs of 4064, 5+ lbs of I4350, 2 lbs of H4350 unopened, 2 lbs of RE26 unopened, 3 lbs of Magpro, 2 lbs of Lil’Gun, 500+ 162 Amax, 200+ 6mm 55gr NBTs, and all kinds of other odds and ends. It was a pretty sweet find!
 
That is a good find! :)

I don't have QL, but have the Hornady manual if you want any info from that. All I've shot from my 6mm Creed is the 108 gr Hornady ELD-M. Holy cow, it's accurate! :)

These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet

Awesome.... thanks Mike!

I’m hoping to see 2900-2950.... as I know this fun shoots the 105 well in that velocity range with with I4350 and H414.

From the looks of it.... I can run 45(ish) grains for 2925(ish) at only 58k(ish) PSI..... out of a 20” barrel. I must be getting old, because that kind of efficiency is far more attractive to me, than milking out that last 85 FPS.
 
I ran the 105 VLD in my wifes 6CM. I had it up over 3300 with RL26 out of a 26" tube. RL26 never gave me the groups I wanted though. I switched to H4350 and lights out groups at 3175 fps. I would think that H4350 or RL23 would be great starting points. Best of luck to you!
 
I’m using Stabal 6.5 for mid 3100’s with the 105 HPBT Horn and CCI250’s, in ADG brass in my 22” Howa. Lotsa great powders for that little devil though. That cartridge isn’t hard to get along with at all!
