Im no stranger to Roys, but at least his more
popular belted family rounds can be purchased
in other brass and munitions brands.

the big departure is no belt, no double radius,
no Wby. freebore, and no parent case to form
your own brass.

6.5 RPM Backcountry - Ti 4.9 lb, steel 5.3 lb
can also be got in 6.5 manbun-Weedmoor,
but no 6.5-284...

.....................................My guess is, is that the RPM will remain a proprietary Weatherby round for quite awhile until Weatherby sells more of their rifles so chambered thus gaining in popularity. Ammo distributors or makers are not going to market a product until there is a reasonably good demand. And besides, if Weatherby chooses not to release or give permission for other ammo makers to manufacture the RPM to then market the ammo to distributors then it will remain proprietary to Weatherby. And I would think that they will mostly offer the Weatherby rounds and the more popular non Bee rounds for the Backcountry Ti......... No 6.5/284 for now.....The RPM is just an elongated 284 anyway.

Curious! So the Bee Backcountry Ti MSRP is over $3K. Well if you are planning on buying one, then the obvious question to me is, why ya complaining about a $65 per box of ammo price tag from Weatherby? Kinda like asking about the gas mileage on $100-$200K or more vehicle. If an average box of factory ammo is say $40 which you will buy anyway, then the difference is only about $25 for the RPM ammo...

I don't put a $2500-3500 rifle in the category
of a $200k + car.

you think folks that have very high price custom
rifles don't look for better value ammo options
because it would be beneath them?

people with money aren't value hunters..? 🤔

Buy the non-ti Backcountry, use that $1000 to buy a boat load of ammo. Problem solved!

I'm more interested in the Weathermark LT, 5.9 lbs and $1550 street price. The RPM looks like an awesome design to me, going to buy a few boxes of the cheaper Hornady load ($45) and save the brass to load myself when does become more available.

IF one 'must have' an RPM sounds like the way to go.

5.3 lb still plenty light for that 6.5 boomer..😁

............Not at all.

Well, I think it has something to offer, but time will tell.

The 6.5RPM case has about 20% more case capacity than the 6.5x284, so regardless of what the initial factory loads show, handloaders should get about 150fps more velocity than the 6.5x284. Basically, the case capacity comes very close to the 264WinMag.

The round was specifically designed for the 6-lug Weatherby Ultralight action (so it's a good candidate for rebarrel of any 30-06 or 270Win rifle), but isn't just limited to the $3K MKV Backcountry. The Weathermark can be had in 6.5RPM for around $1300, and is still fairly light (Tikka) at 6.25 pounds.

Weatherby sells once-fired brass for $1 each, and new brass for $1.50 each. So it's expensive, but not outrageous, and wouldn't factor into my decision for a hunting rifle.

$1300 rifle and $1 brass, that ain't bad.

Yeah, and it's a pretty nice rifle too.

I think a light weight (near) 264WM would be pretty nice to have.

I’m enjoying mine so far. The two factory ammo offerings I’ve used (140AB & 127LRX) have shot very well. The Barnes leads in accuracy at .5” or better 3 shot groups. Redding dies are reasonably priced as well.

I just got one put together, MK5 six lug action and a Wilson #2 barrel in a BC Wby style stock...the RPM case is just plain sexy. I think is has really awesome potential to become a .257...

How much is a NULA in 6.5 PRC ?

As crowded as the 6.5 space is, there are not many standard bolt face, LA options - at least with factory loaded fodder.
Definitely following ...

Bit more than the street price of a backcountry ti but same ballpark.

Watched Lampers crush a bear with the RPM and 140 accubond combo on YouTube.

A little faster than the 270.

I hope you're kidding.

It's not a Roy, it's an Adam. Roy would just use the 257 or270 and kept trucking.

It appears the 6.5mm-06 approximates the same ballistics. A 6.5 Rem Mag on a 3” WSM action would provide the same as well. With all due respect Wby’s 6.5-300 apparently just got thrown under the bus by Wby.

........................Maybe and maybe not. Remains to be seen. In watching the Adam Weatherby videos, the purpose of the RPM was to create the lightest possible 6.5 MK5 rifle. So he had to dump the heavier and stronger 9 lug Bee action and use a 6 lug.

Imo, the 9 lug will always have a very strong following. The question then becomes. Will there be more opting for the 6 lug RPM vs the 9 lug 6.5/300? Time will tell.

In all practicality, the RPM is better. But many are not necessarily practical.

Maybe you will break out of your bubble one day
but I don't hope when it comes to people..

purchased most MkVs at good [pre-owned] prices.
sold some at breakeven and some at good profit.
so id call myself a willing to spend value hunter
by having 5x Roys for the price of three type thing.

Sounds to me like the subject title pretty well answers the question, at least for my needs and those in my hunting group.

The 6.5 PRM won't do anything I can't do with a 6.5-06AI, .264 WM or 6.5 PRC at the same pressures and the last thing I want is a rifle chambered for single-source, $65/box ammo or brass that costs $2 each.

The older I get the more I appreciate my 7mm RM. Weatherby clams 3075fps with a 140g bullet in the 6.5RPM qith a 24" barrel but I routinely run 140's over 3200fps in my 24" 7mm. Lately I've been testing the new Federal 155g Terminal Ascent (B..C. .586) at 3085fps. Wouldn't be much of a trick to build a custom 7mm RM and get the weight down, providing better long range performance than the 6.5RPM and saving a boatload of money for rifle and ammo both

YMMV.

Looked at some base numbers..

Weatherby. Com says 127 lrx (BC. 468) 3225mv
2250/1427 @500yd.

.270win Vortex ammo 129 lrx (BC. 463) 3140mv
2133/1352 @500yd.

Wby promo talks about RPM offering 1500 ft-lb
@500yd., (140AB 3075mv)

Wby offers Ultralight in .270win but no 6.5 RPM
Backcountry offered in 6.5 RPM but no. 270win.

RPM is a cool bit of exotica, but how many would
still settle for .270win which nips at its heels.

Daughter #1 shoots a .270, pushing a 150g ABLR to 2910fps. At our hunting altitudes (7000 ft and up) it retains 1500fpe past 700 yards and just shy of 1500fpe at 500 yards at 100ft altitude.

Should I buy her a 6.5PRM instead? Or maybe just drop her Rem M700 into a lightweight synthetic stock and save enough to pay for 2-3 years of my hunting expenses?

Tough decision. Like trying to decide between dinner out with the wife or a root canal without Novocaine.;

...................LOL...........Good analogy.........Boat loads of cartridge selections, whether they overlap in capabilities or not, make the shooting world go around and around. Always makes for some good conversation and debate.

Hey Coyote..........Tell your daughter #1 to stay away from reading gun mags. Otherwise, she may come to you and say. "Hey dad." "What do ya think of the new 27 Nosler?"...........I haven't run the ballistic #s, but she would get much closer to or maybe even equal a ton of FPE at 700 yards given 7,000 ft of altitude.....lol

I bought my Barnes 129lrx ammo for $27 a box. What’s the rpm cost?

More competition
.280 Ackley145 lrx (BC.486) 3050mv
2141/1476 @500 yd.

What does it do that a 6.5-06 , 6.5 PRC or 6,5-284 cannot do?

What do those do that the 6.5 RPM cannot do?

The RPM was designed to fit in the lightweight 6-lug action, the PRC is a short mag, so what does the PRC do that the SAUM cannot do?

I like the RPM case design the most out of all the others, necked down to .257 it'll be a badazz little round!

.............................A 6 lug Mk5 Weatherby rifle.

You can't rebarrel a Kimber 84L,Forbes, Colt light rifle or similar small action for a 6.5-06?

Be nice if Hornady or someone would load for the 6.5/06. I think part of the appeal of the rpm is availability of factory ammo (even at the higher prices).

Happened to have a chat with Cody up at Weatherby the other day. He told me that Weatherby does have plans to make the RPM available to other distributors.

Proprietary chambering, 6 LUG, titanium,
sub 5 lb for 500yd shots...

thats a rather niche market they aiming at. (grin.)

don't get me wrong - Wby making a 6 lug
and offering such in non Wby chamberings
was a good move.
I always wanted a short action 6 lug.
Had two orig. Varmintmasters, but the
action was too short for 7mm/08 etc.
.250 Sav at reg. oal, a no-go also... Too bad.

One of the reasons I got rid of my 240 accumark was no availability of factors ammo at any of the gun stores I frequent. The second reason is it was too close to a 25-06. I could have sent it to weatherby and had it rebarreled to 6.5 rpm but then I would run into the same problem as my 240.

BTW it is built on the 6 lug long action.

I had my eye on a 6 lug . 240 but never went there.
The DLX 9 lug. 240wm ~ 26" weighed more than
a thumping .340 and was not what I wanted
to carry around,.. ie) .240 6 lug is a hand in
a glove combination.. 👍

I didnt know Wby will rebarrel their rifles at
owners request... are their prices 'reasonable'.?

Dayum Oldelkhunter..ever heard of the internet?

What part of " availability of factors ammo at any of the gun stores I frequent" did you not understand? I had to buy all my Weatherby ammo on that there internet.
