    This has probably been hacked to death but I would like to know opinions of WHAT IS THE BEST CHOICE OF 6MM CARTRIDGES USING THE 85 GRAIN SIERRA GK BTHP AT A MAX OF 600 YDS? I am looking for the max velocity, best bc, highest accuracy and USING THE LEAST POWDER to achieve this end. In other words, what is the best frugal driller available?

    All you need? 6mm BR but I would use 105s personally.
    Best BC, velocity, etc.? One of the .243 variants
    Best overall balance? 6 Dasher or 6mm Creedmoor
    No matter what you WILL have to read the wind at some point. No cartridge will over come a 25mph+ without correction. Embrace it!
    All the above will work at 1000 yds. as well...

    The reason I choose the 85 GK is that I have 23,000 of them.:)

    hope your rifle likes them. not a long range accuracy bullet at all.

    what is this rifle for? if hunting or varmints with that bullet i would just go standard .243. you will wear out many barrels before you shoot up all of those game kings.

    Might not be "long range" but the acuracy of this bullet rivals many of my benchrest bullets in the 6PPC. I am currently using these in a 6BR and a 6x45 with 8 and 10 twist bbls but am interested in more cartridges hopefully using less powder however this may be an exercise in futility. Paper and steel punching only, no live critters.

    6mmPPC
    6mmBR
    6mmx45
    6mmx6.8spc
    6mmDasher
    6mmx47Lapua
    243 Winchester
    243 SLR
    6mm Creedmoor
    243 Ackley
    6mm Remington
    6mm Remington Ackley
    240 Weatherby

    I'm sure I left out something.
    So, Choose your Poison.
    I've had most of these calibers and right now I'm really liking the small primer 6mm Creedmoor , bullet speeds are exceeding the 243 Win.

    A bolt gun in 6BR is kind of a pain. The cartridge is so short, that some, of the cartridges leave the extractor/ejector prior to clearing the receiver opening on Rem 700 short receivers. At least that is what mine did.

    243 Sammi reamer. R15 powder or R16/R17 powder. 26" barrel 1-10 to 1-8 twist. Should be able to get 3300-3500 FPS.

    That is some flat shooting. Don't pay attention to the nay sayers. I bet you could get a load that will shoot better than you can shoot at 600 yards. And you could take your rifle hunting and shoot a deer or a groundhog too!!!

    Send me a couple thousands of those GKs and I will work up some loads in my new 243 barrels :)

    The problem with that choice is the OP would need 23+ barrels in order to consume his stock of bullets.

    Ehhh... People have been shooting that weight of bullet in 243 for half a century... I think you can get a few rounds out of it before it stops shooting.

    You could use N160 to keep the barrel cooler, but it would take more powder.

    Would h-1000 be to slow out of a 243ai with those bullets? I know that powder with the 105's helped barrel life out quite with the 243ai.

    The "no brainer got to" powder would be H414/W760. Use a mag primer. Work up to max, runs very cool, and shoots bug holes at great velocities.

    From an old thread:

    "H414 provided excellent accuracy w/BERGER 80gr in 243Ackley, 1:10 PacNor, BAT action.
    46.0 with sticky bolt lift @ avg. 3581 fps ES14.3 SD6.55
    45.2 avg. 3534 fps ES10.33 SD5.00, slightly cratered primers with NO stiff bolt lift
    Very well suited powder for 80 gr. bullets with lots of velocity potential."

    Now that is an Ackley but, like I said, you should be able to get 3300 pretty easy with an 85.

    It appears that 47 gr of H1000 with the 87 Berger is a honey load

    You are right, Remingtons do have a bad habit of dropping the short fired brass before it clears the ejection port. It can usually be rectified by installing a Sako or mini 16 extractor in the bolt.

    From an older thread:

    Tried and tested loads. Speer 85 grain SPBT BULLET.
    Varget 38.5 grains 3118 fps with a spread of 27 fps over five rounds.
    Viht. N160 44.5 grains 3190 fps with a spread of 37 fps over five rounds.
    46 grains of N160 gave 3217 fps with a spread of 75 fps.
    47 grains of N160 gave 3337 fps but with early signs of pressure, so too hot.
    I use the 44.5 grains of N160 exclusively now simply as I had shot off all the Varget loaded rounds.
    All fired in a Sako 75 with a 20 inch barrel and T4 moderator. Federal brass, CCI standard primers.

    Pick something from the "green" section of this chart. Nothing frugal about overbore cartridges.
