This might be kinda long and rambling and I might know some of the answers I just don't like them...

Quick story:

My son is the luckiest hunter ever. He's 13 and has a 1/2 dozen deer on the wall. He was born that way. First time I took him when he was 3 we saw 5 bucks. I always wondered if it was too easy for him. He's always been a great shot. Neck shoots most if possible, double lung/heart others. He has shot a Ruger American 300 blk out with handloads the last 5 years and has dominated with it. Even head shot a pig with it a couple weeks ago.

My daughters have gotten old enough to love hunting so I got my son a 6.5 grendel in ruger american and passed the 300 down to my daughters.

Long story short he missed a big buck with it opening day. I chalked that up to a weird set up trying to shoot off his knee. Well yesterday he misses another big buck 2x at 90 yds with a field pod. Now I felt he rushed it a little but I just don't see how he missed. It's like this new gun has a jinx.

I sighted it in with ELDM 123 and honestly it was just okay. I could only get 3/4 a box so I didnt shoot it as much as I should have. I also sighted it in supressed and his misses have been without a suppressor. The gun/ammo was just okay. Maybe 3" group at 100 yds.

Anything I'm missing?

I suspect I should shoot the gun again and see whats up. I just don't see how he didnt hit any of those shots. Any other ammo yall would recommend for the 6.5? Ammo is tough to find a the main reason why I haven't done more.


I know TLDR but wondering what yalls experience with the round should tell me. TIA

Find what ammo each gun likes. There is a possibility that you point of impact will change between suppressed and not. I know of people having crush washers on the barrel causing change in zero. Again find ammo each gun likes! Good luck

Silencers change your POI. Some less than others, some more than others. Always shoot the setup you intend to hunt with or sight in suppressed and unsupressed at the same session and find your POI difference. Buy a few boxes of ammo of different kinds and see what the gun likes. That gun should be better than 3” at 100. 3” at 100 is minute of deer for sure though.

Man, this is the problem. The ammo is so hard to get I don't feel like going through $200 to figure it out.

I know that's a bad outlook. I guess I'm getting out what I put in. Also have doubts on the scope. It's a Leupold rifleman 4x12 and I don't know how much I trust it.

I'm torn bc I don't want him to blame the gun bc he's killed everything he's shot with the other one but I can't help but think maybe it is. I guess I'll shoot my last 8 shots on it today or tomorrow and see what happens. It's got me all spun up.

Any production rifle should shoot WAY better than 3” groups at 100 yds with any ammo. Some ammo may be tighter than others, but that sounds like a problem. Who installed the rings and scope?

Raises hand gif....haha


But I've done it a lot and did the 300 blk out that my kids have piled them up with this year.

Have you compared how it shoots with and without the can?

No this is my next step. Like I said the lack of shells is the big thing. So many variables (With/without can, Cold/hot, different bullets, could it be a scope/ring issue not a bullet issue) I just didn't have the rounds to do it all.

I guess I'll pivot to another question....should I commit to the 123 ELD-M and buy 10 boxes so I can go through all that?

If not what different bullets should I Try?

Once again TIA

As others have pointed out, shooting with or w/out a suppressor will change POI due to barrel harmonics. Based on it’s pedigree, the Grendel should be one of the most accurate cartridges created shooting sub 300 yds. The parent case is a .220 Russian or 6PPC which is the most accurate short range cartridge ever created (100-200 yds). The 6.5mm bullet is known for its high BC and lethal accuracy. Combine the two and it’s a great cartridge. I would expect 3-shot, 1/2” groups at 100 yds with a decent shooter from a stable bench.

If you sighted in the rifle with a suppressor, you should be hunting with the suppressor.

That’s a match bullet. Don’t use it for hunting.

I have a grendel in an AR
It is extremely picky about ammo. Best group I could get out of Barnes TTSX was 6” at 100yds. Tried everything. Different powders, different powder charge, different seating depths.

Was about to give up on it and I tried some Nosler ballistic tips. 1/2” group at 100yds with the speeds I was wanting.

Why? That’s a great scope.

My 2c.
Go shoot it at 100 on a stable platform. 1 shot with the can and one without. See if the poi is different. That’s only 2 rounds. And you will know which is accurate or if equally inaccurate.

Also don’t use match ammo. Ron Spomer on YouTube has mentioned this several times. The dude either knows his shite or is a good actor. Regardless I believe what he’s telling me.

Here’s an example how barrel harmonics are changed by adding weight to the end of a barrel, whether it’s a dedicated barrel tuner or suppressor.





Limbsaver and the Browning BOSS system work on the same principal

Do they still sell brownings with this system? 15-20 years ago it was the cats meow. I have a 270 with one but never fool with it bc it shoots lights out as is.

You handloaded the 300 blk. You obviously know it takes time/money to find the right round.

I shoot 6.5G 16" odin works barrel, Q suppressor and only shoot hornady back eldm and the SST. Same goes for the guy I hunt with. We are 99% hunting hogs and coyotes. We prefer the SST but its hard to find.

Your main mistake is sighting it in suppressed and him shooting it unsuppressed. Your POI could be off anywhere from 1" to 12".

Some say the ELDM isn't the best hunting round but it's crazy accurate. We scored 2k rounds at a dirt cheap price so lately we are mainly shooting that.

I'm zeroed at 200yds shooting 1MOA. I can get that tighter also. That's shooting my thermal scope at a handwamer with all rounds inside the handwarmer.
In the last 2 weeks I've killed 5 200lb hogs ranging between 150-215 yds (dropped dead with ELDM), 5 coyotes with 1 at 300yds. My hunting buddy is getting the same results. He's dropped hogs out to 330yds.

I've read a lot of 6.5G being picky with ammo but the ELDM being very accurate overall. My gun needed about 100 rounds through it before I was getting groups good enough to confidently hunt with. Before then it was all over the place. Also make sure scope rings are tight

I didn't. I have a buddy of mine that did them. He did some years ago for his son and had them left over. I just got off the phone with him about the same problem. I'm going to shoot it again this afternoon and see what it does without the can and see what its like.

Sounds like this might be what I'm dealing with. Just not enough rounds through it with all the factors being played with.

In my heart I probably knew this and should've let him take the 300 yesterday.

It's tough though bc he's 13 and I'm trying hard to not do stuff for him. Make him take responsibility for stuff so he'll learn
