Home Forums Hunting & Shooting Custom Rifles & Wildcats Here’s the deal…

I’ve got a semi custom 260 built on a M700SA with a Brux #5 in a MCM A1-3. Fantastic accuracy but I’ve jumped on the 6.5CM wagon with both feet and the 260 does not get shot. 198 rounds in 8 or 9 years…time to move on. Could sell it but that’s no fun.

So….Looking to rebarrel to something else but not sure what. Thinking speed and high BC.
Maybe a 6mm of some flavor, maybe a .224 barrel burner? Not interested in 243, 308 or 7-08 as I have those and don’t need more.

Looking for suggestions on cartridge based on the following parameters:
Must have a .473 bolt face
COAL 3” or shorter ( had the 260 set up with a Wyatt’s box and Williams obendorf bottom)
Barrel max length 24”, but prefer 20-22 as I will shoot suppressed most if not all of the time.

Powder I have in quantity are Varget, R26, R16, R15, H4350, H4895, Benchmark.
Have many others as well but less than the big jugs.
Availability of brass, dies and bullets a must.

Toss me some ideas.

Simply set the 260 back a couple threads and punch 264 Kreed,then trim/thread to 20". Hint...........

I have 3x 6.5 CM. Forgot to mention that. Looking for another flavor.

This is what I’m working with

Good looking rig - go with a 22 Creedmoor. Be sure to get a .219 bore - supposedly easier on the bullet jackets. They are fun and fast.

16-18” 22 Creedmoor or 22 GT.

The chamberings don’t mean anything but the style and type rifle sure would. Sounds like this rifle is a pig. I’d try a smaller contour barrel cut and threaded at 17”. Chamber in 6 whatever pleases you (6creedmoor but I don’t understand how you can like one chambering and not the other it’s just a chambering) twist it 1-7” use a light weight suppressor and stock to your liking.

This would be awesome.

That rifle is far from a pig and weight isn’t the question. I was looking at 6CM. Thanks for playing.

I'd rather shoot 223AI or 22 PPC AFI at 16"-18",mainly because I shoot them along with 22-250,22-250AI and 224 Speedmire. Hint.

I only have (5) 243 Kreed's. Hint...........

I do have a 223AI and that rifle is a pig.

What powder you burning in the 243 Kreed?

'17,'H-4831 and '26. Nothing slower than 8" nor faster than 7",which means a .620 BC 112 plays fhuqking NICE. Hint...............

I’ll toss H-4350 with 105’s in there too for another option. That’s what I shoot in my two.

I’d like to try the 112’s but have so many 105 Hornady and scenars it might be a little while before I mess with it.

Stick have you or any of your friends shot many deer with the 112’s yet? In 6mm I’m totally sold on 105 bthp and 95nbt curious how the 112’s do gather meat.

The 112 is softer,but not zooky. Don't try it,until you are out of everything else,or you'll never go back. Hint..................(grin)

Curious, why would you shoot a 6 creed more often than the current .260?

You’re just bored with it?

You did mention it shoots very well,, What’s lacking?

22 or 6 Creed and if you're using a bushing die for sizing, just get the right bushing. Bartlein BB steel barrel.

Thanks I appreciate it.

284? Or, 30-284? Assuming it's long enough to fit and you have a use for -06 performance.
6.5-284 if your set on the 6.5...
6.5-300 Savage? There was a 270-300Sav way back in the day.

The 6XC is another one to look at. If nothing else, it is a step away from the "norm". With a properly twisted barrel, it will shoot the heavies just fine and Peterson, Alpha and Norma all make brass for it (Peterson and Alpha make SRP).
The Creed has a bit more powder capacity, but it looks as if you understand how to use your rifles for the velocities they actually shoot, so I doubt a 50-100 fps difference will matter to you much.

I shoot multiple 6.5CM all of which have shorter barrels and I shoot suppressed 99.5% of the time.
I could just cut this 260 down but then I have a duplicate of something I already have x3.
Boredom is also a factor.

There’s nothing wrong with the 260 as is. It’s a shooter.

Anyone here play with the 6GT?

Thanks, That just looks like a nice rig has is, I’d be glad to have that one in my safe,

Has a lefty with so few options, I’m often envious of others rifles.

Have XC'd a bunch,but never Gay Tigered. For short/handy,I'm hip on 270 and 6BR,though none are shorter than 18". Hint..............

6x47 Lapua is my favorite 6mm and don’t see that changing. Damn near CM speeds with Lapua SRP brass that with any sense at the loading bench will last forever. 105-112’s +/- 3000 fps from a 22-24” barrel is a nice place to be.

I have a 6 arc freshly cut/threaded at 17” I would be shooting today if stockys would have sent me the correct stock. Maybe next week. I could easily get on board with a 22 or 6 gt either one.

All this talk about speed just go old school and try a 220 swift

Yep. -Al

A lot of the guys I shoot long range with, use them. Excellent cartridge. I often hear them say they don't have to adjust much at all for the wind and they are very easy to load for. Very "inherently" accurate cartridge. Here's a good video on it, from the designer:

I saw that. Intriguing.

Thanks for posting

Would this be a good time to ask the obvious question? What are you planning to shoot with this new cartridge?

The 22 GT sounds like it has what I’d like.

Although I like this 6 ARC Carbon deal, I think the same gun in the 22 ARC might be fun as hell too.

Tim, I plan to shoot paper and game…deer sized down to whatever needs killing’.

How do they load them without "book data"?

After some screwing around with this 17wsm build I’d like to duplicate it in centerfire. The 22gt would be a dandy there.

Ask them..

Will do.

The deer thing probably rules out the .22's. Brass availability is one of the biggest concerns I'd have. Get your brass supply secured at the outset. Rock on with whatever you can dream up after that.

Was flogging on my Wapoint 243 Kreed this morning and playing in the wind at 1400yds+ with 112's. It's a handy NASTY Bitch. Hint...........

I'm really sorry to hear that.

Curious why the deer thing would rule out .22’s?

If I "lived" in a State that precluded .224" bore size,I'd build a 224 Speedmire and the shank would read "Speedmire" and cases would be Alpha 243 Kreed based. Hint.

Fhuqking LAUGHING!..............

Probably, not absolutely. If the chambering has enough powder capacity, and an appropriate bullet is used, then it will do the job quite well. I don't think a .22 would be my choice if the deer are large bodied, midwest types, and long ranges are possible. It's strictly an energy at distance thing.

This will be funnier than fhuqk! Hint.

Cite your minimum "energy" requirements,at a given distance. Hint.

Fhuqking LAUGHING!..............

I totally forgot about the energy part. Good call.

I do not live in the Midwest and I forget about the different energy requirements from region to region. I guess that is why many of us are here so we can learn from others.

So, what energy is required to kill Midwest whitetails?

.224 TTH

That’s a blast from the past! Haven’t heard that round mentioned in over a decade I think. As I recall is was dialed in using the 55 grain sized bullets moving at 22-250 speeds.

I’m looking at the 22GT and 22CM.

Mine shoots a 75 gr A-Max at about 3500 fps

I'm simple....22 or 6 CM.

Have been doing same since inception,ala 22-250AI. Pass the 224 Speedmire,vastly superior brass,far greater COAL,88's and hold The Fluff. Hint.

I've got (5) of 'em. Hint..............

Seriously good read though. Very informative, and very counter to the longstanding myth.

CHIT Stick.......I think you have 5 of everything...........What speed are you running with the 22-250AI?

The 22-250AI and Speedmire,are largely birds of a feather,as capacity/performance goes. 3200fps+ is a breeze in either/or,with 88's. Hint.

Speedmire,22-250AI and CHeetah. Hint.



I drive Alpha 224 Speedmire Virgins,to form 22-250AI and as illustrated,the amount of brass moved is rather modest. I'd never build a 22-250 AI Today. Hint................

Could do a 6mm CM for the easy button.
Lots of options depending on what you want to do with it.

It’s happening….

That was quick.

And now for the coin toss - Creedmoor or GT?

CM

Jealous! I can't find a donor I like as of today!

Day ain't over yet I guess!

Those darn 5R barrels have a tendency to make reamers chatter …

- why (preemptive strike for people that want to tear things down as whinny children instead of helping others)..

Because the incline on the side of the rifling makes a ramp surface contact point when the reamer engages it - this pushes the reamer (chatter baby), on normally rifling the reamer flute hits the side of the rifling edge cleanly without having to dig into a raising plane surface… ]

Frankly I had to be told to look for it before I noticed it… But I had a great teacher so … Meh…

Meaning it is hard to see if you are not looking for it closely - even then … old eyes, ….

I expect the chatter potential has as much to do with the 5 lands as the edge slope of them. With an even number of lands the reamer is cutting a land on each side simultaneously. That is not the case with odd numbers of lands/grooves and the side doing the cutting tends to deflect without support on the other side.

Ya’ll geeking out on my barrel…..that’s cool.

Guilty as charged. A friend just helped me contour and chamber a replacement barrel for my favorite 6.5-06 a couple of weeks ago. You will like a 5R barrel, they clean up easily and seem as accurate as my 4 groove Kriegers.

This will have been my 4th Bart. I expect great things.

Hutch what profile did you go with and length you plan to finish at?

Bart #3 at 20 which will allow for 5/8x24 thread with adequate shoulder. That’s the current plan but plans change….

My vote is 22x47 Lapua. 😂

Where I’m leaning towards too!
