Yes

Lapua obviously makes fine brass in both.

Just wondering if it was solely the 10 or so less grains of powder that was steering him there.

Regardless, it'd be hard to hate anyone of a bunch of 6 mm hulls in a handy little platform.

The 243 is known as a barrel cooker.

Burris discontinued the 30MM Signature DD's,in their infinite "wisdom".

I just want a Dirty Duty Beater Rifle for Utility and whatever velocity it yields with 105's,I'll certainly be able to coax POA/POI intersections ala the reticle and/or erector. That's the least of my concerns and I don't even have any concerns.(grin)

Figured it'd be a PEACH for kids and newbs,while still having plenty of mustard to reach wellllllll past the 1000yd line.

Hell...might even be fun...................(grin)

I've lotsa 243's,243AI's,6-284's yada,yada,yada...them bases is more than covered.

Just want a handy/dandy Squirt Gun of mild mannerisms,for Supreme Giggletitude.

If it sucks...I'll warn others,but I've this hunch,that ain't quite how it'll unfold.............

I have a newish 22-inch 6 BR set up like a sporter, but it's a bolt action single shot. Brux #3 barrel, McM Rem Classic stock, Stiller Pred action.

I've been shooting 95 Sierra Matchkings so far, but I haven't chrono'd them yet.

The 6 BR Lapua brass is very good, much tighter tolerances than the 30-06 Lapua brass I've had. I think something like 99/100 cases had neck thickness variation less than 0.001 inches.

I think the Montana would be an angelic platform for a 6 BR, if it would feed reliably. My rifle, even as a single shot, doesn't extract or eject cases with authority. No biggie for me, it's a rifle intended to shoot at steel and targets, not animals. But if I think I could need feeding to work, I'm carrying my 30-06.

My 6BR is a 26" 1-8 twist and with 30.5 gr. Varget behind 105 Amaxs it gives me 2830. I also have a load with 105 amaxs using 29.5 grs. H4895 for 2850 fps, it's as accurate as the Varget load. CCI 450's are about all you'll ever want for primers. As efficient as the case is I'd think 2700 would be easily doable out of a 20" 8 twist.

I love the 6BR, it's basically my definition of magic. Easiest round to make shoot I've ever messed with. Low blast, low recoil, accurate as all get out. It's only downside is feeding, if the montana action will feed it okay then it'll be a dandy.

Those that have both - why the BR over XC?

I have a 6mm Dasher with a 1-8 twisted Bartlien 5R in a Sendero #13 finished at 26.A un named powder will drive the 105g Berger hybrid at 3077fps.
A 6mm 105g Berger Hybrid at 3000+ is a wonderful thing.
This is on a fullon 1000 yard BR rifle.But its a total joy to shoot.
Thinking your fun gun in a 6BR with a 20 inch barrel will get to pretty close to 2800.We see straight up BRs on the line and they do pretty well.
To do what you want.
I'd think 6x47 Lapua.
A few more grains of powder and even the 20 incher should come alive...
Just excellent quality 6.5x47 brass....you cant get 6XC brass right now...

I just put together a little 6x47L, and while it's accurate and useful, it's awfully close to a .243. Its capacity puts you in the 40-44 grains of 4350, 4831, N160 or similar, and heats a little sporter barrel up accordingly. I think the 6BR is more versatile as you can get impressive accuracy out of bullets weighing anywhere from 68-105 grains, efficiently, and with what's reported to be longer barrel life. I bought 2 identical Krieger barrels (in case I loved the 6x47L so much I had to have 2) and I'm chambering the 2nd in 6BR, throated for 95gr Bergers.

Why 95's?..............

If you get it throated just for something like a 105, (.100+) you lose some options if you wann'a shoot something like a 70 flat-base. The 95 has a short bearing surface and can work pretty well with a .060'ish throat without stuffing 'em way down in the case. That, and a 95 with 31.5 grains of Varget or RL15 just seem to work. Been a while, but last time I tried to get 107's and 105's to do anything special it just seemed like too much cement and not enough truck. Switched to the 95's, and been kind'a fond of 'em since.

Nerf Ping Pong Balls,interest me a whole bunch less than none.

It'll be a 105 Show,start to finish................

I've done the 6BR around the 105 Amax, McClassic, #3 @ 22". Never did impress me much from any perspective. Couldn't get expected velocity and there were no magic in the groups. Went back to the 243.

I'm with stick on this one. Currently building my first custom. 700 action with krieger remington varmint 1-8. 6br cause I love 6mm's and it does amazing things with less powder and longer barrel life. Gonna try 105 amax, scenar, and berger. Also 95 berger. fosnaugh is putting together and should be done any day now. If it feeds like he says my model 7 will probably become a 6br light hunting rifle. Won't have to worry about mag box constraints like I do with most calibers in the 7 action. Should kill deer and other eastern creatures with ease.

Thoughts about Berger bullets.
I shoot pant loads of Bergers.
The Hybrid bullet to me, seems, "fussy". Like a VLD bullet it needs its seating depth to be just, "so", even though they say the Hybrid was developed so that wasnt an issue...
This "fussy" seating depth stuff isnt much of a issue provided you dont shoot it much.But if your pullen the loud lever alot.As I know your prone to do.You end up chasing your seating depth as you wear it out.To keep it in its top accuracy zone.Kinda a pain in the azz depending on usage.
Enter the Berger Long Range Boat Tail.
The LRBT profile is a few points below the Hybrid in BC.And as a class of bullet if you keep it off the lands it just works.Doesnt matter in general where its at, as long as its "off".Start with it "off", and find something it likes and you will pretty much wear it out, with out messing with it.
Actually kinda nice.
Lot to lot Berger bullets can vary wildly.
If you take for granted there the same and you get into a different lot number.You will get burned.

If you do get a BR.And I could never understand why you of all people dont have more BR rounds....Your going to find that it will drill smaller groups at 500 yards than anything you currently have.

dave

I'd expect the Hornie 105HPBT to be the mainstay,but will squirt 'em all,if only in the interest of R&D.................

Making wildcats is fun with guns.

On the practical side a 243 will be easier to find and get.

Also the 243 can be loaded down to near a 6BR.

Just presenting an alternative. A 243 Kimber Montana weighs just 6#,11oz. with a 4.5-14 Conquest on it. Thats what a M70 Featherweight goes without a scope!

The 243's ammo is available everywhere. You will never find 6Br loads for game anywhere.

Wow! Thanks alot!

Does a Montana 243 look like this?



Keep drooling...................

Monster scope on a Montana.. Excellent choice...
