I'd much rather have some crazy performance than a slow coach of a .264 with a barrel that will out-live me It's not the end of the world to replace a barrel. Plus I'll never be firing multiple shots in quick succession. The barrel will always have time to cool, which I'm led to believe extends its life.

You're right, keeping it cool will help. I also believe this cartridge would be a prime candidate for both a Melonited bore & HBN coating of the projectiles.

I was definitely going to use HBN but I've never really looked at Melonite treatment. Just had a quick read about it now and it looks awesome! That's certainly a possibility!

Pressure spikes, weird flyers, and with the real slow powders I get 80 FPS spreads. I assume it is because my 26" barrel is too short???

When I had this rifle built I suggested to the gunsmith that I may like to have my rifle chambered in 6.5 RUM or 6.71 Blackbird and he said no. It is a lighter weight gun so I'm happy but I still wonder what could have been. On the other hand I'm debating whether I should double up for my heavy LR rifle and stay with STW for simplicity sake or go BIG! LOL

Interesting thread... have you actually fired it with 3700 fps? Wondering what powder you used or are going to use. I'm thinking it will need an extremely slow burning powder else you will have a lot of empty case space. The 160 Matrix bullets would be good for this cartridge.

I receive a couple boxes of Matrix Ballistcs 160 gr VLD today. Right after I spent a little time looking for jam length I started to wonder what this bullet and the Prometheus could accomplish?

Rise up all you financially strudy wildcat fools and try one to inspire us! We wait breathlessly for your retun. (Who's been watching a little bit too much "lord of the rings?")


Safe shooting,

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

ya, can't wait to get some of those 160's, called Marshall a few days ago, wanted 6 boxes he only had one available and it's on the way along with a box of his 210 gr 30 cal bullets for my newest wildcat the 300 Wolf (my 338 Wolverine necked down)

This thread died almost half a year ago due to lack of interest in the 6.5 Prometheus, I am surprised it was resurrected now, especially when there are several barrel safe 6.5 wildcats developed by LRH members that have generated a lot of interest...

I frankensteined the 6.5 PRO off my 7.62 PRO which is off the 300 Norma Mag and own the reamer and it has only been used once, when I get my other two barrels in and chambered, installed, headspaced, then reamer will be available to others....

No, I have not fired this cartridge yet, velocity is an estimate based on powder capacity and comparison to another cartridge with similar capacity ...

Rifle was completed quite some time ago, Dies were ordered in December and have been the sole delay in this project, I also was immersed in my other wildcats and time flew by but still no dies..
I spoke to Neil Jones recently, he assured me he will start on my dies first of June and should be done in 2 weeks time, more waiting !!

This cartridge was designed with the knowledge that barrel life will be limited, if one is inclined to dwell on barrel life, go bald worrying about it or become afflicted with bedwetting from bad dreams induced by the terror of less than 2k rounds of barrel life ... well , these little girls need not play with evil barrel consuming monster cartridges ... ( whew ! had to let that out, feel better now!)

all kidding aside,

no......this wildcat is not for high volume shooting, but who cares ? I believe barrels are threaded and screwed on specifically so they can be replaced at any time, otherwise they would be welded on tight
my reason for it's developement ? something cool for my 13 yr old daughter to kill moose and wolves with !

there are several ways to enhance the life of a barrel, my first barrel is for load developement, selecting appropriate propellants and fire forming brass, plus determining actual barrel life using nothing but WS2 coated bullets and a WS2 bore prep solution to coat the throat/rifling that delays the blowtorch effect allowing for more shots fired, imagine grabbing a hot pizza pan with bare hands vs gloved hands that are temporarily protected from heat , ... bad example I know, but hopefully y'all get it !
once a barrel starts showing signs of wear, set it back, rechamber and just as important cut 1/2" of barrel muzzle end and recrown, muzzle washout leads to poor accuracy even quicker than throat erosion ... but all that is old news, everybody on LRH knows all this .

my barrel has a 4" shank for setting back and 30" in length for powder burn and cutting back when needed, it would be a waste of time and money to go with a barrel less than 28" in this wildcat, it screams for the slowest powders, heavier longer high bc bullets and 30" and longer barrels, it may or may not live up to it's potential, may be too much of a good thing but somebody's gotta do it !

Hell, I'm already crunching numbers and necking down my 300 Wolf (500 Jeffery case) to .264" and naming it the 6.5 Zeuss ! imagine if ya can a 145 gr water capacity case, a 200 gr 1.0 bc 6.5 bullet at 3500 fps... hahahahaha... evil grin !

build it and they will come ! (eventually)
