Suppressors - first round impact shift

[Brix8984]

@Formidilosus any update on this or how DD is handling it? The LTI was on my short list as my next can.

I have a DD Lti and it has been great with zero issues. I do not have any first-round impact shifts to speak of. I will test it out on a different rifle possibly this weekend. It is currently on a 20" 7prc.

Well guess I’ll be the next guinea pig. I’ll compare it to my Hyperion K. Hopefully get to shoot it this upcoming week.

Did you get a chance to test this compared to your other suppressor?

I have not. Got busy with hunting. Probably wont get a good chance until waterfowl season winds down. Plan on giving an update though.

My TBAC using 155gr 308 ammo 2900 fps:
Suppressor lowers point of impact 0.5 mil and moves to right 0.3 mil

It increases muzzle velocity 14 fps.

My buddy has a begarra 300 win mag with leupold vx6. I know I told him all about it.

He has a q supressor.

His first shot cold bore is off. Sometimes off the paper. Every shot after is dead center. I had him roll the dial on scope up and down and it would still shoot perfect. We would let rifle cool and take off suppressor. Put it back on 15 min later. First shot wildly off. Then every other shot right where he wanted it.

Thoughts?

Zero it without the suppressor. Then see if it does it unsuppressed.

Put of curiosity, does he use some type of quick detach or is it direct thread? My issues all seemed related to a quick attach system (Xeno) and have completely gone away since switching back to direct thread.

Good question. It is direct thread.

Finally able to get out and “test” my DD enticer sti compared to CGS Hyperion k. Small sample groups because some idiot (me) forgot to check how much ammo was in the bag before leaving. Rifle is T3x super lite in 6.5cm cut to 18”.
Same lot of factory 140 eldm:


Top left is 6 rounds of factory 143 eldx. Bottom is 3 rounds factory 147. And top left is my T3 308 that I shoot once a year to remind myself why I switched to a a lighter recoiling cartridge in a heavier rifle.



Again, small sample size so take it with a grain of salt.

Plan on ordering a case of ammo very soon and will repeat with more shots.
