    OP, if you aren't going to be shooting it a lot, don't go down the rabbit hole of reloading for it. Save the brass you can readily find and sell it. Don't let training or shooting be affected by where your brass goes and trying to find it. If you do want to shoot it more than the cheap Wolf 6.5G steel case is actually decent ammo for training and reasonable accurate.

    Either caliber, stay with a light 16" barrel and low power variable. You will have a light capable weapon usable for short to mid range, well within ethical distances-and user ability. Heck, my son's first 6.5G had an Aimpoint Comp M2 on it, great woods gun.

    Great barrels I've had are the Wilson Combat 6.8 16" lightweight ss, AA fluted 16" 6.5G, LMT MRP 6.8 16" and a Shilen Select Match 18" 6.5G.

    Let us know where you hunt, terrain and distance and I'm sure you will get guidance on optics.

    Nearest 300 yard range is 100 miles from home so I only get there once or twice a year. We have a 200 yard outdoor range about 40 miles away and numerous 25 yard indoor ranges,
    As a result I popped for a DDM4 V5 with a Trijicon 1X4 Accupower for use at those facilities.

    In my neck of the woods .223's are illegal to use for deer hunting and my 30/06 or 30/30 have been doing the job for the last 45 years but I'm getting the bug to use this setup on next years hunt.
    I've read a good deal about the 6.8 SPC, which DD makes an upper for, and the 6.5 Grendel, which they don't. Anyone out there using the 6.8 for deer?
    like somone above said it's tough to get real facts about the two but here are a few.

    As for opinions-I've used and sold the 300BO, Grendel and 6.8. Out of the 3 for hunting I would use the 6.8, it has more USABLE hunting bullets and starts off apx 100fps faster than the Grendel. For longer range target shooting I would use the Grendel, it has more USABLE target type bullets.

    The 6.8 is the best choice for hunting deer and hogs with an AR15.

    I know it's been discussed before, but let's say, theoretically, either the 6.5 Grendel or 6.8 SPC were being considered as a general purpose cartridge to replace the 5.56. I know two of the major issues this presents is that the larger bolt faces necessitated by the wider rims of the 6.5 and 6.8 make the bolts quite a bit weaker. Also, I understand that polymer mags like PMAGs and probably Lancers can't take the larger rounds if the mag is the same width and thickness as the 5.56 mags, meaning your stuck with steel and aluminum mags, or you need new lowers.

    Has anything been done to fix these issues?

    Not all bolts are created equal. Both LMT and JP make 6.8 SPC bolts that are enhanced to increase their durability, compared to a standard 5.56 bolt with just a modified bolt face.

    5.56 magazines aren't compatible with 6.8 and 6.5mm cartridges, even with different followers. There are multiple manufacturers of each type magazines.

    There are no changes required for the lower receiver.

    The 6.8 is a smaller case head than 6.5 and I don't know of any trend of bolt breakage. The 6.5 is a larger diameter so the bolt is a bit weaker, but it also has a lower chamber pressure to help reduce bolt thrust. I don't know of any trend of bolt breakage in the 6.5 either.

    LWRC and Magpul made a larger magwell lower and mag for the 6.8 but I don't think it really went anywhere.

    I completely forgot about LWRC's SIX8. When I first read of a Magpul 6.8 magazine, I got excited.....then disappointed when I learned more.

    Sulzer Firearms is also making a 6.8 receiver set for less than LWRC. I know nothing about that company’s track record, though.
