I'm shooting a 12.5" barrel I turned from a stainless Green Mountain blank and chambered with a Grendel reamer supplied by 4D Reamers. It's one of those barrels that's not truly exceptional with any one load (i.e. not a 1/4 moa shooter) but shoots everything pretty well.Just getting into 6.5G via a Larue upper and holding off on buying any Wolf for the moment.
Success with it seems to be hit or miss, so do you mind posting info on your rifle/barrel?
Thank you. Seems some rifling types do better with the undersized Wolf bullets and others not so much.I'm shooting a 12.5" barrel I turned from a stainless Green Mountain blank and chambered with a Grendel reamer supplied by 4D Reamers.

This rifle is easier to hit with at 600 yards than my 16" 223 Wylde, including with that cheap Wolf ammo.
And those short, Fat bullets have terrible BC's and drop like rocks. we've always known that the 6.8 was great up close, but dead is dead, and the Grendel will kill up close and far out.The 6.8 runs 100fps faster than the Grendel with factory ammo using the same weight bullets and barrel lengths, 200fps faster comparing top handloads to top handloads. 85gr TSX will break 3100 out of a 16" barrel, we can push 110s to 2750 out of a 16".
The TAC6 is a 6.8 based 6mm. 95gr SMKs out of an 18" barrel hit 2800fps.
It’s still flatter and has more energy at 400yds, and has more sectional density than the 6.8 at any distance and speed. That makes it a better hunting round to me. You’re right about 6.5mm bullet designs being skewed towards higher velocities though, that is an issue.There is only a few inches difference of drop and maybe 40lbs energy difference at 400yds using similar weight hunting bullets. I know there a lot of guys on the Grendel forum saying you can kill deer at 650 yds with a Grendel but that isn't ethical hunters saying that.
Many of the hunting bullets being used in the Grendel were made for the 260 at faster velocity, many don't expand at the vel the Grendel can push them. I've been shooting a Grendel since 2005. The Hornady 123 SST is probably the best bullet for the Grendel, Maybe a 100 Nolser.
What is the sectional density of a 6.5mm bullet 1 millisecond after it impacts? You can't answer that and neither can anyone else. The advertised SD of a bullet has absolutely nothing to do with penetration unless the bullet is a solid and NEVER deforms.It’s still flatter and has more energy at 400yds, and has more sectional density than the 6.8 at any distance and speed.

Been eyeing the cartridge since I worked at the NRA in the early aughts but only actually got on the Grendel train myself in the last few years. Disposable income is easier to come by in your mid-30s than your early-20s, ha.
I don’t think there are very many ethical hunting shots taken with any caliber past 600 yds, but I hear what you’re saying about some of the Grendel fanboys. I love the 6.5G but you sure as hell wouldn’t see me try to take an elk with it...even though some do.
1) IME SD is often more indicative of performance on game than ft-lbs of energy, especially with a well placed shot (I think of energy past a certain threshold as largely providing margin of error).What is the sectional density of a 6.5mm bullet 1 millisecond after it impacts?

Well, yes and no. This is just as true for the 6.8 (270) caliber, with a lot of bullets being designed for the higher velocity 270 Win. It is a common thing for the 6.8 guys to point out about the Grendel, while ignoring the same fact about the 6.8 SPC. Both calibers have bullets designed for the lower velocity AR cartridges though, with plenty of good hunting bullets for each.You’re right about 6.5mm bullet designs being skewed towards higher velocities though, that is an issue.
Unless you shoot the lower jaw off and the deer runs off, only to be shot a few weeks later, completely emancipated because it couldn’t eat... When my dad joined a hunting lease in 2005, the first deer he killed was a very “nice for the area” 10 pt whitetail. The deer had 4 bullet wounds in various stages of healing, including a mostly removed lower jaw.Shoot them in the head, no stupid arguments.
No tracking dragging or bs!
Nope, just making a general observation. The shooter that shot the jaw off the deer in question did not know the limitation of his steadiness when staring at a set of antlers through a high magnification optic (this is my assumption anyway, I do not know who shot the deer before my dad did). Like I said, I like head shots. I am somewhat color blind, so I really don't like to have to trail a deer- even one with a double lung hit. I also prefer what Peter Capstick called "halitosis range" as just about anyone can get within 300 yards of a deer.So you suggesting I don't know my limits, proficiency problems or what?
Most deer I shoot are south of 100 yards, not a problem with any equipment I own.
What does a 12" barrel have to do with it? Are you one of those guys who thinks short barrels aren't accurate?If shooting from a 12 inch barrel why not just piss 55g 223 down range?
It's actually a real question.
What length barrel?A short story.
Guy buys 6.5 Grendel. Shoots at a couple matches, cause it’s fun and a great little rifle. It does 1000 fine but wind is twitchy and the factory 123s aren’t as easy to spot at distance. Shoots it one time when out to ELR range and has a picture of a less than 6” three consecutive shot group st 1400 yards.
I was there. Those 123s transitioned really well.
Yeah a 12” 6.5G is still a usable hunting setup for a lot of game. A 12” 5.56 is a varmints-only affair.6.5 Grendel from a 12" barrel still significantly outperforms 5.56 from a 16" barrel in the real world. i.e. shooting in wind, down range power and effectiveness, etc.
If you're talking about Grendel SBRs set up that way, that's your own self-imposed optics setup limitation, not a barrel length limitation. Think outside the box a little more.@Yondering
I have sbr's 10.5 inch, I bought them and set them up for close in work 100 yards and less.
Irons over eotec and 1x4.
They are accurate.
Can't justify shooting with them at 500 yards set up like that.
If the guys shooting them 500 + yards are doing that with similar set ups, damn thier good.
If you stick a 6x24 on them I dont think will be very practical for thier original application.
I have used a 6x20 on them for load development, got dirty looks at the range. Lol
