Thread: Testing the new DELTA suppressor at 534 yards

Hi Team,
I thought I would share last Friday test on the 7MMRemMag with the new DELTA suppressor:

We went to a local range (read private farmers long paddock.)

We thru down 3 shot groups at 100Y for testing:
with the existing muzzle brake,
and then the comparison with the DELTA.

Using hand loads with Accubonds, we pretty much the same grouping, with the Delta showing approx 2" low. Speeds thru the suppressor were up 30fps on the muzzle brake speeds.

Then we rocked out to 534 yards. to see if the suppressor wanted to play the longer game.

Images below show the result at 534 yards. 5 shot group inside of 5".

Pretty happy with these results.

is there a photo of one? what are they made of? weight, price and is there a web site that I can view,
cheers hunty

Yep on to it. Just awaiting a response.

Look not to bad, you couldn't put any photos up just of a stock standard side-on view fitted to a rifle? What thread options are available?

Here is one of it mounted on the testfire rifle.

You might want to change the name. Roedale Precision has been making DELTA suppressor's for the past five years or so.

The chances of Pete doing anything about it are about as good as him actually doing something he says he's going to on time without some long ass, lame ass excuse. Ie non existant

Im courious.....how come the suppressor speeds were higher than the muzzle brake but were shooting 2" lower?.warm /cold barrel? for which one?.or have I just read this info wrong.

The suppressors jetting effect elevates projectile velocity.

And a suppressor fitted alters barrel harmonics, thus altering poi. Its not always as simple as a suppressors weight 'drooping' the barrel.

More weight in the supp causeing muzzle droop (shoots lower)
Almost have added barrel length with a supp sometimes leading to an increase in velocity. Not always the case for every rifle for both scenarios though.
