does a silencer make much difference

[festa 206]

hi lads

well i got a bit bored today so i decided to do a pellet test on the r10 just to see which one matched the barrel better

i have a selection of pellets some i would never use to some ive used many times, the 1st test was with the rifle set up as if i was out hunting

super h point

bis pest control

rws superpoint

bis mags

aa field

jsb exact

h&N ftt

rws superdome

accupell

wasps

here's the results

 

then i decided to do the same test without the silencer fitted i got a bit of a suprise

Considerably tighter grouping without the silencer!

i'd say AA feild with the silencer on.. or, put up with the sinic type loud crack lol. (different silences act differently btw.)

 

 

ahhh.. after thought, a slight tweek on the tuning may well change the results.

What mod is it Festa, HW or BSA VC?

[robwelsh 354]

Superdome and silencer I'd say, cheap pellets, best group, an silence lol

[Skot Ruthless Teale 1,701]

thats mental!

[festa 206]

the mod was a mk2 twink tron mate

[ghillies 209]

some silencers mess with the barrel crown..which effects the pellet as it leaves from a hi presure to a low presure, i.e. from closed in the barrel to in the open out the barrel/silencer.

 

beyobd that.. i dooont nooo lol.

I think the silencer stops the barrel moving up when the gun is shot so no silencer the shots are higher also I think if the baffles in the silencer if not perfect they cause some inaccuracy .So a silencer that is just a well made big empty can is the best silencer for accuracy .a bit bulky and it will still change the point of impact but tight groups. no real proof of this just my limited experience .I have had a whisper silencer I put electrical tape around the baffles 2 or 3 or 4 turns not sure but enough to hold the baffles in the center of the tube .Before the tape they floated all over the place.I also made a tighter baffle for 177 in the silencer the accuracy improved I think .I did not do any strict test to prove this but I do feel this to be correct.

sounds about right..that was a while ago too i tink, i've recolections on it..

 

another is going through a 'cavety' adds another break out turbelance on the pellet.. so 2 changes.

I would try another moderator and see if the accuracy would be improved more than the twink one, at the end of the day its worth a try.

[festa 206]

thats my next test tron mate ive got two to try an hw and a sak ..to be honest the rifle is fairly quiet without one so i might even try that as well

What's the whisper like? Ain heard much bout them

[pianoman 3,587]

Holy smoke that's a hell of a difference Gary.

 

Question is, if you need a mod for a PCP, how do you go about testing one to find one that cures this?

 

Hope you resolve this one mate. I don't like the sound of this!

 

Best wishes Gary.
