if you were building a rifle to shoot unknown range targets

[Eric Leonard]

what would you build,,,400-1200 yards considering barrel life accuracy and speed to help with unknown range targets,,

thinking about 6x47L 6XC 6SLR and 6Rem AI,,gonna try and shoot 105 Hybirds but will shoot whatever shoots best,,

i would like to get around 2,000 rounds and would give up some speed for that,,

 

[Dusty Stevens]

243win. Youre not gonna get that kind of barrel life out of any of em so embrace it.

Just finished mine, I went with the 6SLR

I would think I good clear FFP scope with .1 mil or small moa marks would help you on the targets, especially if the targets were similar or consistent in size. in a couple of thousand rounds you might learn that a pdog that is .2 mil would use a certain holdover or dial up, this might be more useful than another 100 fps. With the FFP scope you could do this at any power of magnification

GAP has thrown it's approval behind the 6 Cred. In that game George has a really deep gravity well. I don't doubt that it works, but I wouldn't choose it just because it's more popular this yr. If GAP came out with something new next yr in 2 yrs it would be the most used.

 

[Dusty Stevens]

Funny how the GAP shooters still use a 243 win. I guess its not "tactical enough" for most folks. Go to a few matches and lose some brass and youll embrace the 243 and remchester brass as well.

A lot of these guys that run cartridges like the creedmoors and such that good quality ammo can be bought do so. They will buy enough to burn the barrel out. I am a 6mm Competition Match man have been since'07 most know that. If I was going to be looking for a 6mm cartridge to do what you want it very well may be a 6SLR, they have the K.I.S.S. factor,decent barrel life, the speed is good with the 105 gr.bullet. With some of the speed limit restrictions at steel matches today my 6CM with the 115 DTAC (Competition Match) had to be slowed down to the next node.
I also believe 100% on what XTR posted about GAP, there is a faithful following there + cool factor. George builds good rifles and supports the shooting sports every day. There's been so many 6's it is hard to choose from one verses the other.


The Surgeon Rifle Team was shooting the .243 few years back. They load all their own ammo and use Lapua brass. You will lose brass, but never enough to sweat it. I've seen a lot of new brass not claimed simply because of what I stated earlier about the buying factory and burning the barrel up, they let it lay.

Would you go with the 6CM over the SLR today?

One, that I knew where shoots , at all distances with one bullet. Don't you have one already? Using it everyday, getting familiar with it, is the only way to know.....

 

[Dgd6mm]

Bob Lee,I have pondered that a few times, and if I had never had a 6CM I may have gone with the 6SLR, just goes to show you I still can't answer that question. Out of my 27" the DTAC runs 3153fps, out of my 30" Benchrest rifle it runs over 3275fps with the DTAC. The only drawback if you can call it that is fireforming brass, which I do not mind. I placed third f.f. at a 8"steelplate 1000 yard gong match at Manatee years back using 107SMK's. Many 6mm Competition Match shooters have placed or won while f.f. so I personally do not feel that it is a stumbling block. My 27"I put on paper at 100, 300, and 600 yards. Accuracy test with 3900 rounds down it. All were 5 shot groups.100 - just under.25", 300 - ?don't remember exact but just under 1", 600 - measured out .4 moa, and I say this with my hand to God. I did have pictures of the 100 and 600 targets. I ran the rifle fast 2months ago off of a wood bench and bipod, 215 yards 5 shot group, point, aim squeeze, run bolt do it again, you get the idea. Group was just under 2".... The 6SLR is like I said k.I.s.s. what's not to like with that? Plus many people are shooting it with good info out there for it, not as many people shooting the 6CM because of reasons stated. The cartridge does everything that Joe Hendricks wanted it to do in his mission statement. Think I'll stick with the 6CM for now, I have another chambered up barrel that is broke in and MMI Trutec treated waiting to go on. I will probably die before it is shot out..... ;D

 

[Eric Leonard]

I forgot to mention one thing,,feeding/ejection from AI 308 mags,,,I have had my Tac 30 Action BRDX in the AI Chassis and it feeds well enough but the short case seems to just dribble out ,,with the 6.5x47 barrel on it feeds and ejects as well as if it were a 308,,I was kinda leaning to the 6x47 but if the SLR will last as advertised I could be persuaded,,

 

[XTR]

I picked the SLR because it it easy and maybe will give better barrel life than a straight 243, maybe, and when I look at it, it looks to me to be what the 243 should have looked like in the first place. Nice neck to work with seating depth, and a 30* shoulder.

If you are like me you are already going to run new brass over a mandrel before you load it, well, with a 6SLR you just run it in a die with a button and you are there. me being me I ditched the button after about 25 cases and still ran it all over a mandrel after I sized it. I don't like buttons much, they pull too hard, even lubed.

 

[Dgd6mm]

There is a lot of good info out there on the 6SLR (6mm SuperX). Robert did all the homework on it like Joe did on the 6CM ( Competition Match). There also have been enough shooters that have shot it to its utmost ability for accuracy and barrel life during different disciplines and powders. It has proven itself in the hands from a novice shooter to a full-fledged competitive shooter. mr.big if you are not persuaded by now, I'm not sure if you will be. If you still have doubts call Robert, he would be more then glad to share his and other 6SLR shooters experiences.

I personally don't think that the SLR is going to have any particularly longer barrel life than the 6-47L . A lot of that is going to depend on how you shoot it. All of these chamberings are so close to being identical that it will never make a difference on a target that you are shoot on.

If a BR shooter were to take them all and try to find out to the last .001" in potential for group size, then one may in fact be better than the others, but as far as I know nobody has done that.

My decision process got me to the point of choosing either the 6-47L or the 6SLR because neither requires fire forming. I went with the 6SLR for a little more capacity and the ability to use W-W brass. (For the record, I have had great results for yrs shooting WW in a 308 in F-TR, I am not a devotee of Lapua so that made it easier)

 

[Eric Leonard]

I really like the 6.5x47 L brass and already tooled for that case,,I have a 6.5x47 barrel at my smith now having it set back and rechambered for the Rem action I will be using for this project,,if I dont have any issues with the small primers I may go 6x47 since he already has that reamer also and I could use brass I have and probably get by with only a smaller bushing for size die and a seater,,

I really like the 6.5x47 for known ranges but it seems the 6mm is a little more forgiving on range estimation,,

If all you have to do is switch the bushing in your 6.5x47L die to size for the 6-47L then that's a no brainer for me. If I were you I'd do a 6-47L.

 

[MOShooter]

Only down side to the 6x47 is it can be very hard to tune. . I was talking to a guy at the last match at shoots one. When it right it's hard to beat. Just hard to keep it in tune. I went with the 6 SLR but might change to a 6.5x47 with my next barrel. Looking for better barrel life.

I guess i'll be the Hucklebery..what's wrong with the 6XC?
I was going to chamber the 243 imp 30 deg..bought the reamer,dies. ect ready to go..I could not do it.
Every cartridge mentioned has to be fire formed or sized to start..there are thing's I don't like about either operation.
But mostly i'm getting lazy in my old age..the 6XC is a no brainer..buy good Norma brass load and go..My new rifle is going to be in 6XC...simple,easy accurate,feeds well from a mag with either 105 or 115's..It really seems to work well..
why no bid's for the 6XC ? it is also well proven. yes?

Is it really the only cartridge in history to fire a perfect score in NRA High Power? Or could it just be David Tubb could have shot it with anything really. How many championships has the 6XC really won? state,local, national?
