Default Accuracy Issue

A buddy of mine and I was shooting his Daniel Defense DD5V1 topped with a Nikon M-308 and we ran into some accuracy issues. He took this rifle on an Elk and said the ride back on horse back was rough.

Well we shot and it 25 yrd was 12 inches. Finally got it close. Went out to 100 and then we could not get a consistent grouping. We used good ammo. Hornady precision hunter 168. The rifle has shot well with this ammo before.

The only difference is we added a suppressor. However, we were trying to sight in the entire time. So I donít see the issue there.

My thoughts are that on his pack out from hunting he really hit something and scope is not functions right. Second thought is the muzzle brake for the suppressor is loose and moving. Next, the rings are loose. Maybe the ammo is doing well the suppressor but Iíve never seen that happen if the rifle already likes the ammo.

What are your thoughts?

Kinda sounds like a baffle strike. Shoot without the can on.

They donít always do that. And you canít always see the impact marks on the baffles. This is the most obvious problem. He may have installed the mount with a crush washer which is not suggested. A slight strike can throw a bullet all over. And if you launched a can with a baffle strike it wasnít tightened down and is probably why it got hit.

The baffle strike sounds the most apparent now. There is a crush washer before the QD.

Suppressor shouldn't contact the projectile. Really shouldn't have much if any affect on the projectile at all, other that the weight added to the barrel, harmonics and the like.
Really sounds like you are getting a slight strike probably at the end cap. I have had this with a customer before, turned out his thread job wasn't concentric to the bore, and it was leaving copper inside the bore of his end cap.
Good luck.

Yep. No QD muzzle brake should use a crush washer. Any suppressor mfg will tell you so.

1) Check all screws on rings and torque to mfg spec. Don’t guess. Use a torque wrench. Generally 15-25 in/lbs on most rings and 65in/lbs on cross bolts.
Shoot 5rd group, see if it fixes it. If not...
2) Take suppressor off. Check for loose mount, baffle strikes, etc.
shoot 5rd group. If it doesn’t fix it..
3) Copper strip and clean barrel. Fire 20rds to re foul barrel and check grouping.

Have a known good shooter shoot it also. Because honestly, most people don’t like to hear this, but they suck at shooting. Even 100yds. I can’t count the number of times I’ve heard someone say they can’t get something to group well, only to lay down behind it and have no issues.

Good news is he is starting with a quality rifle so eliminate one thing at a time till y’all figure it out.

It turned out to be a baffle strike at the end cap.

Thank goodness there is a lifetime warranty on Sig Sauer Suppressor.

Did it do any real damage to the can, or simply a swipe of copper? If just a swipe, I wouldn't worry about getting it warrantied (assuming the problem resides in the mount or rifle threading).

And I agree with the above, crush washers are the debbil. Before I knew any better I mounted a big brake on my manbun using a crush washer. I ended up having to dremel the washer off, it deformed to the point it wouldn't clear the threads. Nothing but jam nuts or shims now.
