I won't even comment on barrel life, or lack thereof, because you don't care! The main thing is, this is what you do and you are having a lot of fun doing it! I'll say one thing, that 160 Matrix at around 3500' is going to be one tough long range pill to keep up with!. Go for it........rich

One of the funniest (& true) statements I've read in a long time, well put.

Go big or go home.

Re: 6.5 Prometheus (6.5 PRO) 140 gr. 3700 fps

Hey all,
Got an update on the 6.5 Prometheus ,

Neil Jones came through and I have my case forming dies, just need to fireform a few cases in my chamber (he wants 3 times fired cases) and he will finish up my loading dies to the thrice fired cases,

Have a fair supply of 160 gr Matrix ( thanks Marshal) 156 gr Norma Oryx, 144 gr FMJ Lapua, 142 gr SMK, 140 gr Accubond and 140 gr Berger VLD bullets along with RL 50, RL 33, RL 25, H 50 BMG and US 869 for the project

Originally I had this cartridge set up for my Sako TRGS and a KRG Whiskey 3 chassis but my wildcats on the 500 Jefferey case have dominated that realm....
since I had a blued Rem 700 in 300 Rum on hand which was considered for my 375 Mjolnir laying around, I had it chopped up and the 6.5 Prometheus is reborn once again !
I had my 29" 8.5 twist Brux bbl all finished and done up for the Sako and alas I had my smith chop the threaded portion off and rethread for the Rem 700 and rechamber, it is now around 27" and will be my fireforming and load developement barrel, I am gonna torch that sucker! haha

rifle specs .....

Rem 700 Mag blued action
McMillan M40A1/HTG Stock in Forest Camo
31" fluted 8 twist 5R Bartlein Light Palma contour barrel, brake machined into extra inch
27" fluted 8.5 twist Brux Rem Varmint contour barrel, brake machined into extra inch of bbl
Jewell trigger
Sightron SIII 6-24x50mm LRMOA2 long range scope
Nightforce 40 MOA base & Nightforce Ultra Lite 30mm scope rings

have some fireforming loads on hand and was gonna shoot today in the area of my out of town construction project but howling winds and blistering frigid temps only allowed me to snap a few pics and shooting session was bagged until a later date, most likely into the New Year sometime !

once I have range results and data I will post on this thread , along with pics of fireformed cases

Congratulations! Looks like all you will need is a caribous address. You might want to salt your bullets so they won't spoil before you get to them Can't wait to see the field results........Rich

Sweet looking rifle! Probably the most powerful 6.5 on the planet. I'm guessing only the slowest of the powders you have listed will work very well with that volume to cal ratio. I think US869 and RL50 are your best bets.

I hope you got 2 barrels because by the time you're done with load development you'll be needing the second one. Yeah, I know, you're concerned about barrel life
