6mm SLR

[Yotebuster]

anyone have experience with the caliber, I like the looks of it, Easy brass to form Little edge on the 243, better barrel life, Longer case neck

Thinking on this for a build I'm saving for

Check out accurateshooter.com. They talk about it quite a bit on that sight. May want to look into the 6 Creedmoor.

The 6SLR is a great 6MM cartridge. If you do not go with that one, there is only 1 better in my opinion which is the 6CM (Competition Match). The only down side to the 6CM is ff brass. With that being said, while ff brass in the 6CM during comp at 1000 yards I have placed in the top 3. I own 3 6CM's and no 6SLR's. If there wasn't the 6CM, I'd be shooting the 6SLR. Over on accurateshooter.com it is always a tuff decision for those making a choice between the two. Oneday I may crossover and try a 6SLR.

I bought a .243 with the SLR in mind; just haven't gotten around to move on it yet. Several guys over on accurateshooter.com have them.

I'm currently taking a break from doing brass prep for reload. I've shot the 6SLR for 2 or so years now and it's been an awesome little round for me. My main purpose for this round is hunting coyotes. It's just so **** accurate. It is easy to make the brass, no fireforming. Just run it through a die and load it up.

With that said, like DGD6mm said, If there wasn't a 6SLR, i'd be pushing the 6 CompMatch.

Both are excellent little rounds.

I've pushed mine out to 1340yds and it does suprisingly well.

This is solid info.gun) 6SLR = SIMPLICITY & ACCURACY !!!!!! Just for the reason alone running the brass thru the die sells me on it. I have a short chambered 6CM that a fellow that said he knew what he was doing chambered a Lawton barrel, long story. Anyhow I headspaced on a Savage action and dummied out and did not put my go-gauge in the barrel first and check it. I broke the barrel in as a regular 6CM with ff loads, then spun the barrel off and sent it out and had MMI Trutec Melonite it. I got it back, then found out it is short chambered by .092. I took my first 6CM die that Dave Bruno made me and had my buddy cut it down. I've been making brass for this barrel just like you would for the 6SLR (SIMPLE).... The case is now 1.970", a little longer then a 6XC. This barrel rocks.... This will be my new Tac barrel when the other one gives up, gonna run it hard.....

I have a barrel in 6.5 SLR Improved.

I know every barrel is different but during barrel break-in and fire forming it was very load tolerant, getting just over 2700 fps with just 41gr of H4350 pushing 139gr lapua scenars(sp?).

The accuracy was one hole groups right out of the gate, opened up at 40.8 and started to close again at 41gr's. I stopped there b/c the barrel no longer was copper fouling and I want to melonite it.

Once I get this and the other barrels finished being broken in I will send all of them off for meloniteing and the real load development begins in earnest.

suffice it to say, I am a fan!

What is a 6SLR improve to..40? My 243AI shoots under 1/4 fire forming with misc. 80 to 83 grain spare shelf stuff. With 49.5 H-1000 and DTACS loaded to mag length ( Big Jump ) maintain that sub 1/4 at 3050ish. The gun will do better if I want to load them longer and single feed. The load isn't showing any preasure so I think I will leave it alone. Maybe play with the powder a few tic's either way and try a few different primers. The 4 rounds ( 243,SLR,CM,243AI ) seem awful close with pennys worth of powder either way. It will be interesting it see how long the 243AI barrel lasts without hot rodding it. I am in a fortunate position that barrels only cost me the price if the tube. Fire forming IS shooting. Exploding grounghogs, shooting short range matches, killing time at the range getting in trigger time ect. isn't wasting barrel life in my world. If I found myself needing every round down the tube for matches I guess it would have a FF barrel chambered off the reamer. The SLR looks to be yet another KILLER 6mm to have fun with. The dynamic of sizing with out fire forming is cool. If I had a reamer I would have one...But THE magic 6 it's surely not....The more the merrier.....Rick

I couldn't agree with you more. I have no issues with fire forming cases. I use reduced loads, so any wear on the barrel is negligible and it is still trigger time.

My fire formed loads have been very accurate in my experience, but the ES is too extreme for long range, but at moderate ranges I have no problems.

It's shooting, so it has to be good.

oops wrong thread.

I agree Rick, while ff and barrel break in at the same time at 200 yards I had groups you could cover with a dime. 3900 rounds later it still shoots under .250 5 shots groups at 100 yards. H-1000 is your friend.

Dgd6mm,
Have you pushed any retumbo through your 6compmatch? I tried some in the 6slr not long ago and was yielding a bit more velocity. But I only ran around 10 rounds at 0.2grn increments to test pressures. Recoil for some reason seemed less also. I may run some 5 shot groups over the chrony just to see whAt the es/sd might run out like.

[Dgd6mm]

Deano,
No I have not. I believe you sent me a pm over on 6BR when you did that. I have 4# of Retumbo sitting here and have yet to try it. I have a 30" 6CM on a Hall action that shoots the 115 DTAC fast and accurate. My come ups show it at close to 3275-3300 fps. I was shooting a shoot lastyear at 800 yards. We were using the 600 IBS target. I had a 99 4x 10 shot group that was 2".... You WILL ALWAYS shoot your best groups playing around ( NO PRESSURE). I need a new chrono before I start doing anything. Nomad47 has done well with 7828 in his 6SLR, I may try it, being that you can find it. I apologize to the OP for rambling. OP the 6SLR is a verygood cartridge, and if I ever see a slightly used one that will spin on to a small shank Savage action with a nut, I'll buy it. But this is highly unlikely... Most people that get them, keep them...gun)

I believe the 6mm SLR is improved to 30 degree's , Longer neck, THe thing I like is run it through the FL die and bang no fire forming trimming or anything go to shooting,
