Suppressed and light barrels

[peterk123]

Any of you noticing the accuracy of your rifle (mine is a tikka t3x lite) decreases fairly quickly after a couple of shots?

My barrel at the muzzle gets pretty warm after two or three shots and then it starts throwing the bullets high. This would happen unsuppressed as well but not as quickly.

I'm not complaining. The tradeoff is worth it. Just takes more time at the range.

No but to be fair only one of my rifles has a tikka lite contour but others aren't much heavier.

what kind of verification do you have to know the heat is causing the issues?

Is your barrel free floated?

 

[Antares]

That does not sound consistent with other peoples Tikka experience. Is your barrel completely free floated? Sounds like you may be getting some contact. Have you run through all your hardware, degreased, torqued, and locked?

How are you measuring this? Not trying to gaslight you but maybe its an issue with your zero/ group size shot to get a zero making it look like things are moving when the gun just has a cone of fire not a laser beam. As mentioned in the linked thread many people have a cold bore issue but most guns actually dont.
How high is high?
What kind of accuracy do you think your gun regularly shoots?

Eta: i do have an ar10 with a pencil barrel that shoots noticably worse - 2moa to 4moa over 15 shots - with a suppressor than without. Doesnt string just opens the group.

You sure it's not a mirage issue? Depending on the temp/wind, I have issues with a 6.5CM and a titanium suppressor after just 2-3 shots.

Can you expand on this? I've been shooting a lot this summer and I have a titanium suppressor as well. I'm noticing a mirage after a few shots. When it gets bad I usually just let everything cool down... Are you saying that when you shoot with the mirage through your scope you are noticing higher shots on paper?

I'm not sure if it's necessarily higher, it's just inconsistent. The point of aim is harder to pin down. I'll settle in and feel like I'm on target, then a gust of wind pushes the hot air off the suppressor and I'm no longer where I thought I was. On a windy day it's less of an issue. Mostly I just shoot 2 to 3 rounds at a time before letting it cool, and with that third shot I might have to fight through some mirage to see where I'm actually pointed.

Same here - Are you planning to run a cover to try and improve this?

Haven't decided. It hasn't been an issue hunting yet so I haven't messed around too much, still pretty new to the suppressor game.

Haha - Yeah that's where I'm at too. For what I do, I only want to use one shot anyway!
