I love wildcats, don't get me wrong, but aren't you basically reinventing the 338 Remington Ultramag(an awesome elk cartridge in and of itself)?

Hi Guys:
OK, here we go:
I'll post a few in the next few days when I get the sucker to the range again.
RL:
Ken recommended a maximum of 88.5 of Ramshot Magnum behind the 225-grain TSX grains to reach a max safe pressure of 50,000 psi.
It's a 24 inch barrel.
At 82, 83, and 84 grains, the chrony did not register due to a shadow. Next cease fire I re-arranged and began getting some love:
86 grains
1] 2820
2] 2784
3] 2817
Avg 2807
ES 35.70
SD 19.97
87 grains
1] 2890
2] 2868
3] 2862
Avg 2873
ES 28.03
SD 14.73
88 grains
1] 2842
2] 2851
3] 2917
Avg 2870
ES 75.38
SD 40.95
89 grains
1] 2966
2] 2955
3] 2954
Avg 2958
ES 12.32
SD 6.63
I might go back to this load, check to make sure it's really this consistent over a larger sample, and mess with seating depth enough to convince myself there's no magic here. Accuracy was not great here, despite the numbers.
86 grains was well under MOA at 100 yards, so I tried it again at 200 yards to see what she'd do:
86 grains
1] 2837
2] 2736
3] 2807
Avg 2801
ES 36.13
SD 18.92 sub-MOA @ 200 yards (Yippee)
86 grains
1] 2858
2] 2822
3] 2857
Avg 2846
ES 36.00
SD 20.49 sub-MOA @ 200 yards (Very cool)
At no point did I experience any signs of pressure, but I could feel the powder crushing at 88 and 89 grains, and groups were opening up.
I'm going to try H4350 (Don Allen's powder of choice in the .330 Dakota) and Reloder 19 for the second range session, and we'll see how far she can go.
I'm especially curious to see what she can do with 250s. I think 3000 ft/sec out of 225s is asking for too much.
We'll see.

Is this going to be available to anyone desiring a custom build? How's that recoil? Thanks for the feedback on the stocks.... jason Jason: Mickey still has the reamer. The recoil is real. About 105 FAST ft/lbs.

Rick-I'd suggest you also give R22 and R25 a go with the 225's and with the 250's all of those plus 7828.
How'd you scope the rig (sorry I must of missed it), also what's it weigh (it about sounds like close to 9 all up) and what does that tube mic at the mzl (.65-.67" I'd guess). And how long is the tube?
Many thx and keep us in the loop, the world of the big 33's is for sure a cool one!
Lastly, did you apply for elk in Montana again this year?

Wow, what a great story! Love the logic for building "another" ultimate rifle! Also, neat that you involved all of your Campfire buddies, Mickey ,Ken, et al. Can't wait to hear "the rest of the story" and see the pictures!

I use 91gr of RL19 and 225gr TSX in my 358STA and it flat shoots!
With your new .338 Campfire its a little more over-bore than my STA so I would think RL22 with the 225gr TSX mite be the powder your looking for!!! :GRIN:
Last edited by RL KURTZ; 01/18/08. Reason: edit to read 91gr not 93gr looked at my reloading notes..

Tom, We need to start calling you 'Mr. Overbore' or perhaps 'Barrel Burner!'

Somebody did already do the 6.5-300 Weatherby Wright-Hoyer at this powder capacity. This one gets my personal label of "over-bore". The 6.5-300 RCM would be interesting though. jim

Yeah, I cant help it Im a 6.5 slut. Me too, Tom. I only have a 6.5X55 right now, but I have been 'jonesing' for a 6.5-284Norma and/or a 264WM. Ah well, one of these days! HunterJim, I didn't know that someone did a 6.5 on a 300wby, that thing must scream...

Yeah 340 somebody did, as a matter of fact there is one on Gunbroker right now.
My dream is to build one on a 378 Weatherby case with a 34" barrel, just for S&G and see what kind of velocities I can get with the 140 grain bullets.

I think being banned would beat a wedgy, Dober!  Seriously, I think Rick should give us rifle loons some pics to drool over!
