I just picked up a nice Howa second hand, with low shot count.
It came with a Hushpower 370 suppressor. Without suppressor, it is a tack driver.
With suppressor its anyone's guess where the projectile is going.
I've checked and no clipping.
My other rifle has a DPT - and poi is the same with/without suppressor.
Should this hushpower join the scrap pile and replace? Are they known to be a problem?
hey man, my mate has one on his tikka 308 and that things on point.
good supps at least his is ;)
Sounds odd, my old MAE can was 8 inches low and a few right. I put that down to the weight of the thing.
Maybe set up a target with plenty of white space around it to see where they are going, it may still be grouping well but with a significant change in POI.
Have a look inside the suppressor. Is there any possible impingement?
Nup - can't see anything. That was the first thing I checked.Quote:

Definitely won't group.... its erratic as.
Is it contacting the barrel by the bushing?
Nope - has about paper thin gap.Quote:

As in going from a golf ball or there abouts at 50m out to not even on the a4 paper.

I've got a howa m1500 in 708 with a hush power 370 and it's got sub moa grouping.

How do you know for sure it's not clipping anything? I have seen more than one terrible threading job on a hush power suppressor including one where first shot came clean out the side of the suppressor, punched a nice hole in it.Quote:

Just for completeness for anyone searching threads in the future.
Situation has been resolved with a very tight rear bushing, as in just contacting.
As soon as the bushing was put in, rifle was shooting tight groups at 50m - bang on a target - was 1" high at 50m without suppressor.
I'll lift it slightly, but very impressed with accuracy now - and shout out to the good guys at GCity Wgtn that gave me the bushing to sort it out.
bullets dont actually need to clip the suppressor to fuck with accuraccy
if they go close the disturbance is enough to cause mega issues
shine a light in the breech end then look thru the supressor. is it concentric with the rifling ?
Me too. A mate had one on a ruger .270, couldn’t hit jack with the hush power on. He replaced it with a HRE suppressor and it shots mint now.Quote:

I'll try slipping some thin paper around it and test if there is any clearance - is no clearance a problem? Even if its shooting well?
I'm happy with it now and will shoot it until the suppressor dies, then replace with a DPT. Have a DPT on my 308 and its faultless.
I got the gun 2nd hand with the suppressor which was near new, so happy to persevere rather than just spend if I don't have too. Its just a goat gun and will have a heap of rounds through it, so I imagine the suppressor will not last very long.
