What do ya'll think about a 6.5-375 Ruger?

True; I remember now why I went with the .050. I am using 270 WSM cases, but I am shooting single shot only. .200 is all I need to grip the bullets. I know nothing of the Dakota cases except that they are incredibly expensive the last time I checked. The first batch of 270 WSM cases used all split the necks as the case it quite brittle.
The next batches of cases I annealed and have not lost a case in several loadings. I did lose the entire first batch of cases do to split necks!

Since it is a short barreled application I haven't the luxury of a lot of barrel to burn the slower powders. I have only used Rel 17 and slower powders in testing this cartridge. I also only hunt these days so settled on the 100 and 125 grain partitions as they flat out smoke anything caribou size and smaller out to 600 yards( self imposed limit).

If I were still wildcatting, one thought I never pursued was cutting back a 300RUM case and making an extended WSM case. But, I never did because I did not feel I would have been able to get enough velocity return for the amount of work required to make the case.

This little cartridge on the Savage action has NO brake and my recoil sensitive wife really likes shooting the 6.5WSM from a center grip Striker application.

I have a neck length on the 6.5 X 65R Imp of .200. I have a neck length on the 30 Gibbs of .190. Neck length on the 338 X 65R .195 and ignition is always positive, velocities are always consistent and pulling bullets with a collet puller makes me confident that I have a good solid hold on the bullets.
 
I'd think you'd need a slower powder than R17 for the 6.5 Ruger. That's a lot of case capacity for that small hole. Using R17 in the 375 Ruger is a lot different than using it in the 6.5 Ruger.

I'm with this guy on powder. Also, even treating your barrel, I think a rd count of 1200 may be more in line, unless the Berger 140 hybrid will compensate for your throat loss. Even nitrided, with that amount of slow burning powder, you'll be able to measure throat erosion on an outing basis:rolleyes:
 
Hi Y'all,
New member , first post.

I got this 6.5/.375 Ruger "idea", last week, and after making some dummy brass I googled this thread, to see who has done this before.
I have abandoned the "6.5 Creedmost" moniker.
"6.5/.375 Ruger" or ".264 Ruger" sounds good to me.
Here is my dummy work:
First step from .375 Ruger to .308/.375 Ruger, using a .338 Lapua Magnum die, then a 300 Lapua Magnum die, then a 300 Ruger Compact Magnum die to smooth out the neck and shoulder:

Then a 28 Nosler FL die and a 26 Nosler FL die are used for the necking down steps from .308>>>.284 and .284>>>.264:

Seems like the 6.5/.375 Ruger corrects the rebated rim of the 26 Nosler and is not quite so inefficient (i.e., the case capacity is slightly less). :)

I am making the transition from big bore to small bore after falling for the 6.5 Creedmoor in Ruger rifles.
This is a 6.5 Creedmoor-more (Creedmost) so it ties my old big bore shooting habits to some new small bore tendencies for me.
No psychiatric help needed.

Anyway, it should be easy to make-do until custom dies are available, but if you are a settler you won't need to bother at all:

"Jebediah is plowing his front yard when his son runs out of the house and asks why they can't have [strike]DirecTV[/strike] a wildcat 6.5 CREEDMOST like their modern next-door neighbors. Jebediah explains to his son that they are settlers and that they settle for things like [strike]cable[/strike] only using SAAMI approved cartridges. The son asks if that means they also have to settle for less fun in life. His father explains that it does and tells him to go churn some butter and make some clothes."

Well Eddy, here's what I'm scheming :rolleyes:.... I had a chat with my gunsmith yesterday about a 300 WSM build I've contracted him to do and I asked him about nitride treating the barrel for better velocity and extended barrel life and he told me that it would greatly extend the barrel life, about 2-4 times.

Well this morning I had an epiphany about going with a 300-375 Ruger instead of a WSMlightbulb. I have also been wanting a 6.5-something and figure with a nitride treatment, I might get 2000 rounds or more from a 6.5-375 Ruger.

What velocity? I have had great results with RL17 and my 300 WSM and 25-06... 200 fps increases in velocity over other loads. And I think the 375 case is a good candidate for RL17. I plan to develop two loads for it, one with GS bullets (which are very spendy) and another plinking/fun load with maybe E-Tips or something. GS will develop a custom bullet to my specs, so I'm guessing about a 120 gr, high BC (.55-.6 ish) monometal pill. And GS bullets get about 100 fps (give or take) better velocity than other bullets because of driving bands and molly coating.

Sooo... If we look at Hodgdon's data for a 120 gr bullet in a 264 mag, they show 3300 with Retumbo. Conservatively add...

100 fps, RL17
50 fps, GS bullet
100 fps, increase powder capacity
50 fps, 5C rifling and nitride treatment

... which gets us to 3600 fps... and just maybe 3700-3800 fps.

All speculation of course, but I have little doubt that this will be a sizzzzling combo :)

I ran a wildcat 6.5 made from 9.3X64 Brenneke. It has a 26" salt bath nitride treated barrel. The case holds a couple grains more than a .264 Win Mag. It started with GS bullets. Here's some info with that bullet:

April 6, 2015, temp about 80* (kept the ammo inside my long underwear)
I fired two shots, walked to the 200 yard target and marked the bullet holes. This gave the barrel time to cool between each two shot string. The primers look okay and there was no bolt lift resistance. I will load 72.0 and up to 76.0 and try again.
Load: GS Custom 106HV @ 3.400", CCI 250 Magnum, H4831 (from WW2) @
64.0 – 3271 feet per second;
64.5 – 3269;
65.0 – 3313
65.5 – 3344
66.0 – 3426
66.5 – 3389
67.0 – 3407
67.5 – 3466
68.0 – 3486;
68.5 – 3527;
69.0 – 3546
69.5 – 3621
70.0 - 3627
70.5 – 3676
71.0 – 3701
71.5 – 3692
72.0 – 3761;
72.5 – 3785;


April 10, 2015 about 80* (loads inside long underwear)
Load: GS Custom 106HV @ 3.400", CCI 250 Magnum, H4831 (from WW2) @
72.0 – 3,754 feet per second
72.5 – 3,804
73.0 – 3,833 sticky bolt lift All the rest were disassembled
A little side note:
I loaded up some with Federal 215 Magnum primers. I had to pull the bullets because they generated too much pressure, even with the 71.5 grain load.
 
I would consider another bullet, and just throw in in a RUM or 338LM case. I am having 180 bergers shedding jackets on my last couple of trips out.

My other 6.5 wildcat is based on this idea. I use either 7RUM or .300RUM brass shortened to the .338RUM shoulder giving the case a longer neck. After trying several bullets clear up to 160 grains I settled on the Barnes LRX 127 -.120" from the lands. Before using HBLN it liked -.180" from the lands.
 
AH HA!
Kiwi Greg actually did it a couple of years ago, not just second-hand hear-say about a guy the internet forum poster knows who did it:



http://www.longrangeonly.com/f...1b9f8756b22ed9cb7e96

He called his the "26 Terminator."

"It is my version of the 6.5-375 Ruger, shooting the Cutting Edge 120 at 3550-3575 fps & the Berger 140 Hybrid at 3320- 3350 fps into 0.5-0.75 moa."

"Based on the 375 Ruger, 86-88grains of RL50."

"I wanted to use the Cutting Edge 130 but the 1-9 twist is to slow even with the velocity."





"It has a Rem 700 Titanium action, True Flite UM 26" 1-9 barrel, Talley rings, Leupold VX3 4.5-14 x 40 with Alumina caps, light weight firing pin."

"It weighs 2.69 kgs, 5.9 lbs with the Terminator wooden stock in the pictures, 2.81 kgs, 6.2 lbs with a Carbon one."

Very interesting:

My new pet wildcat, the 26 Rip, is a WIP:

I need to decide on the throating, then get a reamer and gauges, and a supply of barrels for re-barreling (slightly less often than with a 26 Nosler).

I'll have something similar but based on 6.5x68 brass. I wanted something with tough brass and RWS brass is about as tough as it gets. The only down side is the .511 case head size versus a normal magnum of .532".
 
The 6.5 Creedmoor has a "Weatherbyesque" throat: :cool:
Parallel-Sided-Free-Bore diameter only .0005" over bullet diameter: 0.2645"
Parallel-Sided-Free-Bore length greater than one-half of bullet diameter: 0.1992"
Leade Angle: 1.5 degrees.

It is gratifying to know that this sort of throat does so well on the 6.5 Creedmoor, and it is just the sort of throat as on most of my wildcats. Now for the 26 Rip ... :cool:
