How fast do you think you will be able to push it from that case? Glad to see they are going to make it to market.

Shooting for 3300 fps with the 195 gr. Berger Elite Hunters And 3400 fps with the 180 gr. Hybrid Target bullets This is a long throat set up for 100% use of case capacity in a 30" 8tw X-Caliber barrel ........ ....... ]photobucket[/url]

When truth is ignored, it does not change an untruth from remaining a lie.

What's that case based off of? I just opened up a box of 28 nosler brass and layer one next to a 180 hybrid.with the bullet body /boat tail junction lined up With the neck/shoulder junction the coal looks to be about 3.58". Should be just about right for my 700 ultramag action. A little room to chase. Now I just need to find a good smith with a reamer.

I'm also wondering if I should have Rock make a run of 8.3" twist 7mm barrels. I had them do some 8.5's a while back and they all sold. The one I have on hand is 8.75" but it has a little gain twist on the spout end too.

A Rock Creek barrel in 8.5 tw sounds good, they normally have a slight gain and you will end up with 8tw at the muzzle,
They just shipped me a 30 cal in 8 twist for my 300 Werewolf (308/500 Jeffery) wildcat that will be used to test the new Flat Line high bc 30 cal bullets, and I also got a 375 cal 33" 7 twist Rock for my new long range wildcat project the 375 Warlord based on the 585 Hubel Express, Russell at Rock Creek has been awesome to work with and my orders were filled in less than two weeks, the 375 cal barrel is intended for 375 gr and 400 gr Cutting Edge MTH bullets and Berger Bullets have some heavy 375 cal bullets in the works !
My Long Range Hunter series of wildcats are off the 338 Norma Mag case with maxed case dimensions and throated for long heavy high bc bullets..... have five in the stable 7mm LRH, 300 LRH, 8mm LRH, 338 LRH and 375 LRH, ballistically exceed the Lapua and Rum cartridges in a much shorter coal, designed to run in 5 round detachable magazines from Accurate Mags as seen on rifle in pic .....
Barrel round count should be around 1200 rnds, that is a lot of dead critters !
I have no special connection and undying love for a barrel, it is an inanimate object, a chunk of metal with a hole drilled through it .... The threads cut into it on the fat end make them easy to remove and replace, why do people not get that ?

Got an 8.5 twisted Rock shooting 180 scenars and 168 hybrids quite well. Just not sure how fast my 7mm Remington can push these. Maybe 2700 fps out of a 25" barrel?

I'd like to know what pressures you would be getting with that bullet at that velocity. Remington's 7mm Ultra Mag 3450fps with a 140 grain bullet, with 110 grain H2O cap.
You can piddle with the puppies, or run with the wolves...

Man I'd love to send a few of these down range. I'm sure Shane and I could have some fun- me with these 195's in my 7-08's, and him with 230's stoked in his .308's

I just found a good load for the 215 hybrid in my 300 wsm. It's only clocking 2800 at the muzzle but they really carry well.
I wonder what the 28 nosler will run these 195's at. I'm not going any longer than 25" on the barrel.

Bb Contact Ryan Pierce @ Piercision Rifles ! He just got a 28 Nosler reamer and throated at 3.7" coal with the 195 gr Berger Elite Hunter.. for zero case capacity impact with bullet, velocity with 88.5 gr RL33 was 3120 fps when he got pressure, 8.5 tw 28" Brux barrel My 7mm LRH has a 30" barrel and 8.5 gr more case capacity so I'm hoping RL33 will get me to 3300 fps

I've never heard of a 7mm long range hunter how does it differ from a 28 Nosler or 7mm LRM?

The 7mm LRM is on the 375 Ruger case and the 28 Nosler is on a shortened 7mm Rum case ..... both glorified to run in standard 30-'06 length actions at 3.340" but are handicapped by shoving the heavy 7mm bullets deep into case reducing case capacity needed to make the long arse high bc bullets fly, in order to run the 195's in these cases the bullets seat with bullet ogive in case neck, leaving an exposed rim of the case mouth to get deformed/bent ........ Both are great cartridges but to make them really shine you need to throat them properly and run them in long actions with minimum cartridge oal @ 3.650" , at least with the heavy bullets, with the usual 150-140 gr bullets you don't have that problem but for true long range those bullets are useless when compared to the 180 and 195 gr Berger Hybrids
The 7mm Long Range Hunter (7mm LRH) is a wildcat I developed off the 338 Norma Magnum parent case dedicated for long range type of bullets like Noslers ABLR, Berger Hybrids, Cutting Edge MTH, MTAC and the custom heavy RBT's.... It does not have the "30-'06 length" castration even though the case is shorter than the other two, it's fatter at the web and I imp'd the top of case to gain more capacity, With the 195 gr Berger Elite bullet seated for zero impact on case capacity the cartridge oal is still only at 3.530" .... With the 180 Bergers oal is 3.507", the shorter , fatter and longer neck case has 8-10 gr more usable capacity than the other two and works exceptionally well in Accurate Mags ...
Cases are easy to form from 300 Norma or 338 Norma Mag case by cream or wheat fire forming or with a hydraulic water die from Whidden Gunworks, check out the video on Whiddens website for more info ......
Developed for long range hunting so all the concerns of the overhyped and abused term "overbore" mean absolutely squat !

In the Barnes #2 Reloading Manual from 1997 the top velocity for their 195 gr Original bullet is 2710 fps in the 7mm Rem Mag with a 24" barrel using AA8700 powder ...
the Barnes Original bullet was a cup and core bullet with a very long bearing surface , the new Berger 195 gr Elite has a much shorter bearing surface at .665" in length , that should help get the speed up a bit before pressuring out and with the powders we have now you can get better velocity but may still need an 8 twist barrel

I've talked to Ryan Pierce before back when he was just getting started. He worked with Jim See at Center Shot Rifles before Jim went to Surgeon. Jim was one of my favorite smiths and Ryan uses the same chambering methods Jim did. I'd trust Ryan but I want a little less freebore. I don't mind if the 195 sits down in the case a bit I want it to Kiss at under 3.6" so I can run a factory rem mag box and have a little room to chase. I'm guessing a reamer with .200" freebore would work for me.
