Suppressors Accuracy with and without suppressor

[normbal]

This topic has come up several times in this forum, and I finally got around to shooting with and without my suppressor.

Winds were messed up this day, but I tried shooting in calm periods. Hopefully you can read my chicken-scratches on the targets. Rifle routinely shoots better than I can, under 1/2 MOA even without the suppressor (you know, little caffeine, no wind, sun behind me, got laid the night before, all that).

Take it for what it's worth.

Doug Melton makes a very nice can. This is the 8" shadow, threaded. Most common comment I get about it is "that's quiet." The THWAK! downrange is a lot louder.

Very nice, have you ever experimented with accuracy at subsonic velocities?

lots of folks here routinely do UKD matches and hunt non-game with cans to great aplomb......

I was curious about this particular can. Different baffle designs have shown different accuracy quirks during my own experimentation.

I've thought about it, was more interested in making up rounds that were truly subsonic at a range of temperatures; from shooting squirrels with a suppressed 10/22 using remington factory subsonics, I knew a twenty-degree temperature difference could make the difference between hearing click-thwack or click-bang-thwack. I'd rather the neighbors NOT hear the bang part.

I played around with making subsonic loads for weeks (180 grain sierra round nose over about 8 grains of bullseye with a standard rifle primer and light crimp gives about 1050 fps and 440 ft-lbs - enough retained energy at 50 yards to drop a 110 lb doe); keeping notes on how accurately I could match powder load with velocity for shooting in different (non-standard) temperatures and density altitudes (I used to fly light planes).

Accuracy is under an inch at 50 yards. I can pretty much hit between a deer's eye and ear. I'll make a point of putting some rounds on paper in the future.

I'm looking forward to that. I've seen a difference with a 44 caliber wildcat we dreamed up, but I haven't done a precision test with anything else. The 44 does a bang-up job on deer with a subsonic 460grain lead round nose.

Re: Accuracy with and without suppressor

I remember reading an article detailing the accuracy differences between suppressed and unsuppressed accuracy, I'll try to dig it up to post it here.
