largest case per caliber choice?

[ARlife4me]

With more and more people using suppressors, barrels they choose get shorter even with big magnums. I don't remember if it's this forum or another, someone built an "xp" type 12-16" barrel in 338lm or 300prc (maybe both)? Goes to show people will build what suits their needs or wants.

I'm sure Rigby wasn't expecting suppressors!

Probably someone has put a suppressor on 1 of his BIG BORE rifles .

Not going to argue john rigby makes a work of functional art, but globally how many rifles do they sell a year? I'm guessing a week of sales from just one of the mid tier rifle companies puts more rifles in hands than rigby.


In one of your later posts you talk about playing with a shorter barrel 7 rem mag in the 80s. I'll raise you one, in the 2010s a local smith used to sell takeoff and surplus barrels for pennies on the dollar. At one point we cut down from 26 a 7 rum, a 7 rem mag and a 7 wsm (they were savage barrels and 25 to 50$, so we also did a 270 wsm that we did exhaustive testing on as well as 243 and a 22 250). There certainly is a point where muzzle blast gets annoying and there are points for all cartridges that velocity drops off significantly. However, there are sweet spots that a growing number of us are gravitating towards.

Buddy traded out a rifle that came 24 inches with a break in 6.5 creedmore for a 21 inch 6.5 prc with a can. The can plus barrel is the same as his creedmore but significantly quite as well as a slight bump in performance for the same oal length rifle. Not all trends are totally baseless, shorter barrel with can works for a lot of guys.

Agreed, and well argued but no sale. I have no interest in a barrel extension for a hunting rifle where if most are being honest about their shooting prowess, is a single shot per kill.

For me, not even if provided free, would I thread any barrel.

I do not own or want any suppressors but just enjoy hunting with shorter bolt action rifles which are much lighter for a 70 year old to carry.
I just got back from my hunt camp where as a last practice session I killed a granite rock (18" by 24") in our lake with my Rem Model 7 .308 with an 18.5" barrel. I glassed it with my Steiner LRF binoculars at 430 yds. From now on that is my limit for hunting with the .308 Win. Next week I take my 300 WSM which I limit to 500 yds. Too much fun

Fair enough, that's my feelings on the 6.5 creedmore. Doesn't matter it's merits or the solid arguments in favor.... free or not I'll pass.



Back on subject.

In early grad school we took a course prepping for our thesis. Basically we picked any subject we were passionate about and practiced the mechanism of narrowing down subject towards a thesis. In my case it ended with me chopping down a couple 270 wsm barrels with a chop saw and shooting a myriad of bullets and powders. Another fellow in the class was also a rifle looney, he did initial "literature review" on scouring the forums to answe the question of what's "overbore". Basically he was trying to answer the question, at one point do you run into harder to source or overcome quirks.


Idea was a 7 rum does just fine in what at the time was a relatively normal length (24 to 26 inch) barrel, but our own effort with a 6.5 rum and threads we found on 25 rum or similar capacity cartridges indicated the need for 30 inch barrels, and we're limited at the time to botique bullets and one or two powders.

This is dated info, as a lot has changed since 2010 in powders and sleek bullets... well that and it rely on accuracy of data mined from forums in the early 2000s.


Rum class cartridge seemed to need longer barrels, limited powder options around. 277. The wsm/saum/rcm gets hard to work with below .257. The then popular 284 based wildcats did alright to 6mm but forays to .223 need a long tube, finicky choice of bullets and powder.

Now obviously folks have gone more overbore with all those categories, but they really don't pencil unless your launching heavy for caliber bullets in longer than average tubes and you have prodigious quantities of powder with wet sawdust burn rates.

I'll say that the smaller the bore with same capacity brass you waste powder as there's more existing pressure.

I've played with a fair number of overbore cases ranging from 22/30-06 AI up through 338 and 375s on improved CheyTac cases. Sometimes you're just going for the most performance possible with no regard for efficiency, and it's always fun!

My favorites have been the 6.5x338 Rum Improved (we called it a 6.5 Badger) and 338/408 CT improved. The 338/408 CT improved was done with both 20" and 30" barrels, and we tried 18", 24", and 30" barrels for the 6.5 Badger. There were 270 RUM and 270/338 RUM improved barrels too, but those were all very finicky to load for.

 

[Victor3Ranger1]

I have wildcats on the following cases, WSM, Belted mags (full length), RUM & Rigby Improved.
The most successful for me have been the Rigby Improved cases, they start at 30 then 338, 375 & 408 (still developing that one).
Have considered 7mm, but the 7RUM is ample case capacity.

300 Weatherby for 6.5mm is ample case capacity, or even a 6.5STW, which I had several years ago. Have done a 6.5-270 Weatherby, but that and 264WM are neck and neck.
I really love my custom 264WM, it is amazingly accurate.

Cheers.

I just received a bunch of 264 win mag brass, now I'm looking for the rifle to use them in

They will neck up to 7mm Remington quite nicely.

They will neck up to 7mm Remington quite nicely.

That's how I got my current 264WM brass, by necking DOWN 7RM Remington brass. It's not as good as my original Winchester 'ww-super' brass, but it'll do.
The Norma brass is soft and EXPENSIVE!

Cheers.

how many firings did you get with the ww brass? i'm on # 24 with that brass from the late 70's and early 80's

 

[MagnumManiac]

@ARlife4me
Around 20 so far, never had an issue with any of it.
I also use it in 2 other factory chambered 264WM rifles. Just changed my Win Model 70 EW over to re-formed Remington brand 7RM brass.

Cheers.

You're missing out. It doesn't get much more fun than a good suppressed 308 bolt gun. Screw a heavy contour carbon wrapped barrel on that model 7 finished at 18-20" and put your choice of a titanium can on it and report back. Your only thought will be, why did I wait so long.

I'm with you on the creed cream. I just can't choke it down. If somebody gave me one the first thing I'd do is run a 260 reamer in it. Or maybe a 6.5x47.

i only jumped on the manbun wagon because it's a 26cal, then found a 260rem. i have very few bolt guns and any short action w/ .473ish face i have is in an ar (243win, 6.5creed, 260rem, 7-08rem & 308win so far). anything larger than 30cal in a 308win/creed type/similar case, i'll pass. maybe do a 277fury (65k max) in an ar with up to 150's?
