Howa mini 6.5 Grendel

[arnie]

Maybe i expected too much of this rifle but it doesn't shoot very good at all. Factory ammo is lucky to hit a foot square target at 100 yards. my loads for my AR15 Grendel are better but nothing to rave about. So far I found AR Comp to be the tightest shooting, but still not great. I put the barreled action in an Oryx stock and put on a muzzle brake and still no improvement. I'm about to give up unless someone has an idea.

Do you have a bore scope? How old is the rifle, is it still under warranty?

Barrels are always a crap shoot. Every so often one gets a turd! I know I have. I just sent one back last week. BNIB never been fired by me Christensen Arms 6mm Creedmoor. I was well aware they had had QC issues in the past, growing pains, too popular, too fast and trying to pump out too many units. I had hoped they had turned the corner and solved the problems, nope! The free bore/lead ream job was wildly off center! Two lands were basically untouched and went all the way to the edge of the chamber, with zero freebore/lead. Berger factory ammo was .035 jammed! The rest of the gun looked great, fit and finish was excellent. Carbon stock, Trigger Tech trigger, 5.5 lbs, on sale……..stuff happens.

Sounds like you got a lemon, you can send it to me and I'll dispose of it properly...Joe

It has an MOA guarantee, send it back.

My HOWA MINI 1500 6.5 Grendel shoots all sorts of bullets into 1 INCH and less groups - many can Be -3/4” .

Check the torque in the action screws and scope mounting. Don’t go over 35 inch/pounds on the action screws or you will break the plastic magwell/trigger guard. I has a Remington that couldn’t shoot inside of 4 inches at 25 yards and it turned out that the action screws were out of balance. One was barely finger tight and the other went “pop!” When it was unscrewed. Get them equal before doing anything else.

Good suggestions above. Mine is the spotter model and shoots superbly. Really cool little rifle that my son has just about taken over. Gonna be hard to part with that one

Definitely, something is off. Mine does 1" at 100 yds. I am a terrible shot, so that 1 MOA is all me. The rifle feels like it can do better. I used Boyd's laminate stock and bedded it myself. Be VERY careful torquing the bolts.

Did you resolve this?

factory loaded 123 SST spreads like 4-6 inches for me, but handloads with 123 SST shrank it to around an inch.
But thats just the rifle not liking the boolit. Anything else in the 120-123 grain weight shoots half moa, if not better.
A friend has a howa mini grendel and he shoots 108's really nice.

123-140 grain has worked wonders, almost no load development needed just 95%+ casefill and its a winner.
