7mm/6.5 Weatherby RPM

Words of wisdom or pearls before swine? Unfortunately reinventing the wheel overwhelms us all at some stage. The 280AI is an exceptionally good cartridge and very efficient to boot. I have a Sako .270 begging to be upgraded...

What's the powder capacity of the .280AI? What's the capacity of the 7-6.5RPM?

To take something from drag racing: There's no substitute for cubic inches!
 
Jud96 give us an example!
Of course you realize that is still $1500-$2000 more!

Also if I may add, one is a custom rifle, and one is a factory rifle. Yes it may be a very high quality factory rifle, but the attention to detail, the options, the customization, and overall quality from rifle to rifle is going to be superior when you have a custom rifle built. No hate towards the Weatherby at all, but a custom rifle whether from us or any of the top level smiths and gun builders in this country on average will be the better rifle.

Hijack! Time for a hijack! Where do you get your stocks? What would be the lightest you would go with for a .338 RUM? Do you ever use Christensen carbon barrels?
 
Sorry I hijacked, this thread is way off tangent and I apologize for feeding into that. I'm done responding
 
I like the 6.5 Weatherby RPM and the Weatherby Backcountry 2.0 rifle.
That rifle is likely THE best mountain rifle on the market.
1.) titanium action
2.) carbon fiber stock
3.) Trigger Tech trigger
4.) carbon fiber tensioned barrel (the best way to do a CF barrel for consistent accuracy)
5.) spiral fluted bolt (lightens bolt and provides a place for ice, dirt & debris to go and stay out of the bolt path)
6.) radial muzzle brake

Those features in a custom rifle would cost many thousands more than the Backcountry 2.0.

Disclaimer: I have a 6.5 PRC Browning X-Bolt Pro that is "one step down" in features from the Backcountry 2.0 but still a fairly advanced mountain/long range rifle. The Weatherby is what I'd call state-of-the-art at this time. I'm partial to 3 lug bolts and light (accurate) rifles.

I know this wildcat may be too new for anyone to have experience with it but I'm going to ask for discussion and experiences anyway. I don't need to hear about what's "better", more efficient, more popular or any other alternatives. I want to know about this wildcat. PTG has drawn up a chamber reamer for it and that looks to be just a simple neck opening of the original brass. Maybe the gunsmiths and developers out there might have some interior and exterior ballistic insights that might inform about this cartridge. Thanks in advance...
I got my hands on nne of the first reamers available and just used a 7mm pilot to build mine.i have 4 different ones now on that cartridge and I love them. The same or better performance of their belted magnum brothers but you gain an extra round in the chamber. Win-win!
 
The RPM case is unique and cannot be formed from a parent case. We tried. If someone has it figured out, let us know. Now that Peterson is making brass, I see no need to look into forming from anything. Neck it up or down and run with it.
 
If they ever made a 30RPM I would have one of the first!
Sorry, I beat you to it and it's so close to my 300 Win mag it ain't funny. I just went with rechambering a new 700 Rem 30-06. It does have a 25" barrel. I've picked up every piece of 6.5 RPM brass I could find since it came out. I think I have about 350 pieces and have a 270, 7mm, 30, 8mm and 35 that I've built on the case. Looking hard at the 338 now but I really don't have a need, just an extra barrel laying around.
 
archeratlrg,

Your 35 sounds very interesting. What bullet and what velocity are you getting?

I have one that duplicates the 8mm RPM. I get 3,054 feet per second with the Hammer Hunter 198 grainer and 3,120 with the Hammer Shock hammer. The rifle weighs 7 1/4 pounds ready to go. It's based on the Weatherby Mark V ultralight with a 24" barrel with a .650" muzzle.

Recently I was thinking I need to buy one of the Back country 2.0 Ti. I think it should be rebarreled to .35 before it is even fired.
 
Funny how weatherby states "magnum" in the rpm. Nothing magnum about it! Magnum in terms of a 7-08? .213" longer case body with .500" dia is far from magnum status. Still could be a good cartridge? .228" case body longer than the 6.5x284, but still no magnum. Have fun and hope it turns out good for you!
