Who here likes 6mm Remington?

And all that happened before I was even born. There were certainly no 244's around in the Ruger catalogs of my youth. As for the name sounding European well I never worried about that while my dad was using it to kill meat. Like I was 4 years old and he said thats a 6mm. Would have been no different if I pointed at a jar and he said thats peanut butter. OK dad sounds good to me.
NOW that we are done hearing the obligatory "Might as well get a 100 fps slower 243" and the obligatory "244 history" which has begun every 6mm article , reloading book and thread since 2005 I would like to reopen this thread to contributions from those folks who are loading for and hunting with the excellent 6mm Remington. I give you your 6mm thread.
 
Difference is 100 FPS with like bullet weights. Not enough to matter one way or the other.

Done a little looking, and seems the faster round can be either one.

I'm kind of the other end of most of the folks who have .243/6mms. I have both, and they aren't target rifles or varmint rifles, and they're on exactly the same action.

Remington Model 600 (the .243 is a Mohawk 600, the 6mm is a Model 600, vent rib and all).

Short, light barrels, they don't do good 5 shot groups well, without a lot of cooling time, but first shot spot on, next two shortly after very close, they do that well.

Never bothered to chronograph them, or work up "to the lands loads" (which probably won't fit in the short magazine anyway). They are pretty light handy, carry well, and do their job well. I also have 600s in .222, .308, and a magnum in .350. Not match guns by any stretch, but good game guns, and pest guns.
 
Remington 788 is typical of what one should expect from a "price point design"(at one time $100). The stock was birch and chunky. The magazine was OK and it's single stack design worked well enough. The trigger was not conducive to precision shooting. The rear locking lug design was strong enough but tended to stretch cases limiting the number of reloads. The barrel was topnotch.
I killed several coyotes at 300-400 yards with a 788 in 22/250 before swapping it for a 700 with a far better trigger.
 
"Looking at a few cartridge dimension drawings, I always wanted to believe this but never had it confirmed. Woul that open a Savage short action up to being rebarreled for a .257 Roberts?"
I think that at least the 100 gr. would fit...

Come on people...
Can't find ammo or brass... This is why we reload. 7X57 brass is cheap and plentiful.
It't how i have so much 257 Roberts ammo.

As for taper..
Some slight modification to the lips on the mag. Big deal.. We all work to some extent on our own guns, right? I modified(filed) my Mauser mag to shoot 284 Win.
And don't start on the "rebated rim", no feeding issues here!

I'd take the 6mm Rem over the 243 Win. Push some Berger VLD Hunting bullets with a load of RL26, and hang my deer in the fridge.

Do you have a big fridge or small deer?
 
The 6mm is a super fine bullet. The 6mm Rem, 6mm creed, 243. win, 6x47, and the 6br norma are all great shooters. I confess that I don't have as much experience with the 6 rem than I do with the 243,6 creed,and br but all will shoot inside of .3 @ 100 yrds. with custom loads. The 6mm CM with a 7.5 in. twist cut groove barrel is simply amazing.

I've loaded for two 6MM rifles (both Rem 788) and found both shot best using Hornady 87 grainers and a powder that filled the case. Both needed to be pushed to close to max for best accuracy.

I have a Remington 788 in 6mm as well. I replaced the trigger with a Timney a few years back. I love this gun! My load: IMR 4350 45.0 gr – 2.825 COAL – Sierra 85 gr HPBT

Very accurate!!!
 
Well I took out an old 6mm the other day to try some new loads. Kind of bittersweet as I found my loads consisting of RL17 and 100 gr. Sierras werebeing out shot in velocity, and accuracy by some Hornady 100gr. interlock SP Am. Whitetail! At least those were shooting very good. Good thing since we have a quantity of it. I had recalled some nice hunting with 6mm over the years, and one very nice thing is the lack of recoil. It is just point and shoot, no flinching or sucking the gun in tight getting ready fir a punch. And it does hit hard at least out 200yd. certainly further. A broadside shot, decently placed at 200 yd. could very well be a pass through. That was my experience at least. I generally use only 100gr. Sierras, 100 gr. Hornadyor 90 gr. Accubond, or BT Hunting bullets.
 
When I was young, almost every article I read referred to the "twins". They were about the new .243s.
I couldn't afford one, but I sure could read and dream.
Over the years, I never bought on, but I'd borrow whenever I could.
The second wife was a southpaw, so we bought her a Savage M110DL in .243. I made her reload it, so she'd shoot it as much as possible. She brought down a muley doe with it with one shot in the right place at about 125yards, and all was well the world.
I remember the bullet was a 100gr Sierra spitzer.
Time went on, and the third wife used an M722 in .257 Roberts. After she passed, I decided that I needed a 6mm of some kind. I had lengthened the magazine in it but was unhappy with the chamber because I couldn't get the ogive near the throat and fit in the magazine, too.
I decided to build MY twins...
I bought two Pac-Nor 24" sporter barrels, but since most twins are a bit different, I got an 8" twist 3r for the 6mm, and a 9" 5r for the .243.
The M722 is mounted in a thumbhole Maple for the .243, and a Maple Monte Carlo sporter was cut for the M98 Mauser that will house the 6mm.
The .243 mounts a Weaver K10 and the 6mm a Leupold 3-9x Variable.
As I am edging into my "sunsets", I have enough time to experiment with my toys on the range with my chronograph in tow.
As soon as the parts are assembled, I will drop back with a report on the results.
I bought a "couple" boxes of bullets and a "few" cans of powder to try out.
Have fun, (I will)

I recently picked up a fine-shooting Cooper in 6mm Remington. I can’t remember ever having my .243 Winchesters out of the safe since.
 
I've had one, a Remington 700 ADL, for over thirty years. My rifle shot best with two Nosler bullets that are discontinued, the 100 grain Solid Base and their 75 grain bullet.
.
I use the 95 grain Ballistic Tip over RL22 now, although I don't use my old ADL as often as I used to. As posted on another thread, I'm using PPU brass now. It looks good and shoots as good as any Remington or Winchester brass I've used and recently it seems to be available whenever I've checked.
 
The 6mm Remington is a good caliber. The 6mm Remington was introduced in 1955 as the .244 Remington: The .244 Remington was a market failure because Remington envisioned the round as suitable for varmints and medium game and designed their bullets accordingly. i own both a .244 and a 6mm.

Some "experts" have blamed the 1/12" rifling twist rate for the lack of popularity saying it was too slow to stabilize 100 grain bullets: That ain't so. i load several different 100 grain bullets that shoot very accurately in my .244 rifle.

Remington re-badged the .244 as the 6mm Remington and gave the barrel a 1/9" twist rate. My model 700 in 6mm Remington is very accurate . So is my model 722 .244 Remington.
 
Does a SA Savage bolt gun handle the 257 Roberts?

My 4.4” screw spaced receiver does. I have not loaded bullets in excess of 100 gr. yet though.

Somebody did not like the trigger on Remington’s 788. Well a gunsmith can tune them. I bought and had a Canjar single set installed on mine in 22-250 788 and it was a fly shooter until the barrel gave out. Still have it. Should get it rejuivinated!

The 6mm

Mine was in a Rem 760 and was lost to thievery before I got down to tack driving with it. I like the cartridge and have owned enough 243 Win chambered rifles to know I like the bore size and that cartridge as well.

As a handloader, I would not back away from a 6mm Rem project for even a moment. For a non-handloader, I would stick with a 243 due to the better choices and ready availability of factory fodder.

The real potential in the 6mm Rem is in the AI category. A 243 win in AI does not gain as much boiler room potential as the 6mm Rem does.

Food for thought

My bud has two of them. He thinks the 6mm is way better than the 243 round. His reasoning is that the 6mm is a hundred FPS faster so that makes it a much better killer. And the neck on the 6mm case is longer than the 243.

I keep telling him that of the hundreds of 243 rounds I have loaded and shot not one single time has a bullet ever fell out of the case. And all the new WSM and other short action rounds that came out a few years ago all had bullet diameter case neck length necks. And they work fine.

As for the extra speed I feel if a 100fps makes the difference between a clean kill and a lost animal you are using a round way too small for the game you are hunting.;)
 
I shot 6Rem and if I'm not mistaken the 6Rem is higher SAAMI Spec pressure vs 243. 6Rem use couple more grs powder for that 100ft gain.
 
My uncle used, and really liked the 6mm in a Remington 700.
I can't remember his load, but it was a 105gr Speer Spitzer, over IMR4831.

He killed deer, at least one elk, and a bear with it. It was his light walking around gun.
His heavy rifle was a .270. But he really liked the 6mm.
 
The 6MM Rem. is not something that I had a big hankering for, but I could not pass up the deal I found on a model 700 at an estate sale over a decade ago.

I had the trigger/safety modification done at one of the Remington authorized gunsmiths who had a shop in Springfield VA only a mile from my place of employment. This particular smith had a great reputation and I think he went a bit beyond what he was required to do. The trigger on this rifle still breaks at an "authorized weight" but it is smooth with no creep at all.

This particular rifle is not the least bit sensitive to bullet design as I can load it up with any of the popular 100gr. bullets and it hits to the same point of impact at 100yds. with all of them. It shoots consistent 1" to 1 1/2" groups if I do my part.

It is also not too particular about powder, but I have consistently achieved my best results with H4831.

I would definitely recommend this cal. for a re-barrel or for a new piece.

This post is coming from a shooter who is also a GREAT fan of the 257 Roberts.

I don't have a great deal of experience with factory ammo. It may not be available at Wally World, but I have seen it at most independent shops and it has always been available at the gun shows at a reasonable price.
 
I have a Remington Mod.7 in 6MM that I bought the first year Remington made them. Has a Nikon 3x9 in Leopold mounts. Hand load 100 gr Nosler's and Hornadys and they shoot great. Have killed several deer here in the Adirondacks and think there is nothing better to hunt with.
 
I am a .270 guy, but after shooting a dozen woodchucks and most recently (last week), a deer, with my son's Remington 700 SPS in .243, I am in love with the caliber! Ammo is available almost everywhere. With a Nikon Prostaff scope,
I can blister quarters from a rest at 100 yards. With lighter varmint rounds fired at woodchucks, it is explosive and leaves a cloud of pink mist. With 100 grain bullets, it drops deer as quick as my .270.
