looking for a 6mm suggestion

I currently have a remington VS in 243 that I am strongly considering rebarrelling into a different 6mm cartridge. Thing is I can't decide which. The purpose of this rifle will be as a good paper puncher but also used for coyote and wolf duty with the possible whitetail hunt thrown in. Barrel contour will be smaller than a remington varmint/sendaro, probably a number 4 shilen or slightly heavier. It will need to feed reliably as well. I already have a dedicated paper punch of a 6.5x47L. What would you guys suggest? I am not against going with a 243 again but I was wanting to see what else I could go with. 6xc, 6mm-250, etc I am just not a huge fan of a difficult case forming procedure. Any suggestions?
 
I have a 6mm SLR forming brass from winchester or hornady .243 cases is easy as pie. I have read that higher end brass gives people trouble but have not tried it myself. Brass is easy to get. The rifle shoots really well I'm happy with this choice so far. I guess only time will tell about barrel life. The 3100fps with berger 105 bullets makes me smile its performance at long range is very good. I would recommend the Whidden dies they are excellent. I think the 6x47 would also be an excellent choice.
 
6xc seems to be pretty inherently accurate, my insite 6xc is a laser, as is every one I've seen that they've chambered.
Brass is available through norma, but not as easy to source here as lapua.
6x47 would be my choice.
 
6x47L has two draw backs in my mind...... Accidentally getting a round mixed up with my 6.5x47L being the main one. The other is the theory of small rifle primers being a little light for igniting 35+grains of powder.
 
The only time you will notice a real problem of small rifle primers is using a dense charge of ball powder and on those super cold days.
 
Of the above mentioned the 6slr is the most economical and it shoots very good. The 6xc shoots just as good but brass is a bit tougher to come by and about double the price. Gary at bighorn has a big pile of 6xc brass in stock right now tho. I have a pretty big soft spot for the 6xc, I own 3 of them and they all shoot lights out.
 
Without case forming headachs and very accurate the 6BR, and the next step up is the 6 Dasher, either one are very accurate and barrel life is good as the Dasher uses 31-32gr of Re-15 with the 105 berger, velocity approx 2900-3100 depending on barrel.
 
I have built several Dashers. Brass prep is not all that onerous and 25 reloads is typical. Pretty good chance of real world sub 1/2 MOA accuracy.
 
I will have to look into the dasher. The 6mmslr has my interest for sure. Anyone know a smith with reamers for the slr?
 
243 will do just about what ever you need it to
105 bergers at 3150 avg and shoots in the low .100's and sub that quite often. 6xc can run em in the .100's on 7 to 8 round groups and has some speed at 3280 avg if you burn the RL17. No brass prep on the xc and will go 20 plus reloads on a piece of brass if its run in the 3050 fps range. Everyone says its no issue with brass prep till your the one doing it and wasting what time you have to do it to gain nothing on some rounds where there is no need...just my point of view...what ever you pick its hard to go wrong on a 6 or 6.5
 
furtaker - I'd get that 243 into International Benchrest where in 2015 the Nationals winner agg'd a bit over 0.15 at 100yds. Didn't look at the eqpt list, but I'd bet it was with a 6PPC.

Any 6mm built will be a pleasing gun to shoot. But if you already have a target rifle why not go the extra jump and get a hard shooting version. The 6mm Remington as already suggested is a good choice as it gives more velocity than a 243 with a longer barrel life on account of the body shape and longer neck. Myself I would jump up one more notch and do a 6mm Ackley. Faster again and you get great barrel life compared to a 243 because of the case shape and longer neck.
