6mm Rem or ???

Ok I'm gonna start another 6mm thread..

I'm looking to get a 6mm to shoot 115 VLD's and would like to be around 3000 FPS with H1000, this will be a hunting / varmint rifle.

I've been looking at all sorts of forms on the 6 Creed, 6 SLR etc.. but there's not much out there on the 6mm Rem.

Anyone have experience with the 6mm Rem, SLR, or Creedmoor?
I plan on building on a Tikka action so overall length is not an issue

I've had the Remington for a long time, and it will run with some of the newer choices.

Supplies favor Creedmoore, and that's what I'd pick from the choices given.

Given a free hand Rich Sherman's 6 mm SST would top the list.

6mm AI! Get Norma 7×57 Mauser brass. Run through 6mm Rem sizer die and fireform.

WAY more than 3K. With 26" barrel you will get upwards of 3150.

Wouldn't trade my Cooper 6mm Rem. for all the tea in China.

Thanks guys
I'm liking the looks of the 6 Rem, anyone tried H1000 with the heavies?
The Ackley version has my interest as well, might be a good option to have the extra capacity to fill up with a slow burning powder, my only concern would be feeding reliability for hunting situations.

I have a fast twist 6mm Rem. I have not shot it for a long time, so no chrony data, but I could load up some heavies with H1000 and take it out next monday and let you know what it does. I have some 105 VLDs, Amaxes, and some 107 sierras I could load up.

All depends on what the max COAL you have planned. As you only plan on one bullet the extra long neck of the 6 Rem is not giving that much as it does when you plan to use many different bullet types. But it does allow for getting the bullet out of the normal powder column without sacrificing neck bearing surface contact. With that said if you are working with a receiver mag combo that offers plenty OAL then it would be my pick.

If you really are only using one bullet then I would get it throated with the bt/bearing above the neck shoulder junc some min distance. With its long neck you still have plenty of bearing surface neck contract to chase the lands if needed; again COAL restriction being taken into account. I think you would be looking at a COAL around 3.05-3.1 keeping the one junction above the other. Take that and sett the freebore allowing for the 20 tthou jump them seem to like.

I think its a great idea to use the h1000 as it one of the coolest temp powders in that range and should lead to longer throat life as well is known to produce very consistent loads. Loading long if possible will allow a given peak vel at lower peak psi which again should add to increased throat life. The hybrids seem to like about .020 jump so I would factor that into the freebore spec.

If this is for hunting have you considered the 103/108 ELD bullets. Also, just an FYI, unless you are going to be shooting at elevation with the 115 bergers it needs a fast twist; 1:7 ideal, as you likely already know.

Thank you that's some great info.

And Riflehunter1776 I would seriously appreciate a little test data with h1000!

As much as I HATE anything with the word "creedmoor" attached to it (other than the range itself), I have to vote for the 6mm Creedmoor. And here's why...

I love the 6mm Rem, it's a fun cartridge with ZERO recoil, but brass is ****-near impossible to find these days. I had someone wanting to trade me one several years back, but I never did. I love the 6mm Rem AI version even better. The 6mm Rem would do better in a long action, or a mid-length action rifle.

Also, the 6mm CM will fit better into a short-action with the longer high BC bullets than the 6mm Remington will.

Mudrunner,
Are you talking finding it locally because I have had the same issue but online its never been an issue. At least not when I have needed it. It was my grandfather fav for yotes and the small TX deer found around I-10 corridor west of Houston. It rubbed off on me big time so......

For example of its availability online, right now: grafs , midway, cabela's. Between then there is Hornady, Prvi Partizan, Wincheser funny how they did not have rem brand for a remmy round LOL. That was just the first big shops I checked and all had it one or more brands.

Then if you are either in a real jam and can not find any or want rock solid high pressure cases you can pick up 7x57 RWS and form it to 6 Rem. A bit of a PITA but they were doing it for the 6 Crusader a blown out shoulder body 6 Rem wildcat.

When I get a rifle setup I usually always buy enough brass for a few barrels worth. If its a hunting rig that is a life time.

Now I will say if the remmy is a no go and since it seems you have no issue with COAL I think the SLR would be my choice over the crapmoor LOL ( just kidding its a GREAT round I just am naturally averse to anything that mainstream with that kind of koolaide following even if it really truly is a great round) The SLR needs nothing more than a single cycle thru the fl die. You get a much nicer neck which can be put to use in a nice long COAL receiver.

I have really always been a fan of long case neck, long sleek high BC with their stretched COALs when seated ideally. Its why I end up with wildcats so often I guess LOL. Its one of the things I really liked about the sako trg-22 when I bought it. Detach mag with just shy of 3" COAL clearance. We won't mention the mag costs though !?@#@?

But really, if you are building Remmy now, go pick up 300-500 cases as you can get them currently and you are all set for a few life times or more of hunting. Minimal size, anneal frequently, keep pressure within reason, and they will last and last.

Last time I looked for it (when that dude wanted to trade me) I couldn't find any online or locally. Granted, this was 4+ years ago, when brass and components were near-impossible to find, thanks to Ohomo and his gun ban threats after the Sandy Hook false flag push.

I would go with the 6 creed. The 6mm rem is a superior round ballistics wise, but brass is definitely an issue. No quality brass manufacturer makes brass for it, and it seems to be scarce.

Here Is a post asking questions about the 6mm rem That might help you.

It looks like a real performer and brass can also be made from the 7x57 mauser cases.

J E CUSTOM

I'm currently having a custom 6mm Remington re-chambered to a .243 Winchester. I had some "issues" with that chambering that admittedly had nothing to do with the cartridge itself. The Douglas barrel I ran was a 1-9 twist and at my lowly 500 foot elevation I just could not consistently/comfortably stabilize any Bergers (or other long-for-caliber bullets) over 100 grains. As other members here have stated brass will be an issue for you. Brands like Lapua, Norma and Nosler don't make 6mm Remington brass (that I'm aware of). At the time I was working with that cartridge I could only get Hornady brass and it required A LOT of prep work and had a pretty large weight spread. I have since seen Winchester brass for it at Cabelas.......
