Yes indeed, but I would strongly suggest that whatever maker (certainly one in this country) will have tested the rifle with a heavy pellet to make sure it does not go over, I dont know if its the case still, but Daystate always state that their rifles are tested with bis magnums, hence most doing 10.5 ish with a light pellet, and 11+ with bis mags, that said I have seen new rifles fitted with anti tamper, doing over the limit with heavy pellets, not by much, but nevertheless still over, food for thought.

Daystate sent a test sheet back to me with the regal saying , tested with daystate sovereigns 8.4 gr a low of 11.4 high of 11.8 average of 11.6 .

With those figures a jsb heavies would be over 12.

I tested with my chronograph and one at rfd and the DS pellets 8.4 still only putting out 10.8 . On other forums there has been post after post on daystate exaggerated test sheets !!

 

 

No, not test sheets, works of fiction!

Very true mole

If the police have a rifle tested at a lab (which most do and have to pay for) the "lab" will use the heaviest pellets they have (in a pcp) usually Bis magnums, I have even heard a horror story (although I have no way of knowing if its true) of the rifle being tampered with to make it go over the limit, after all the law says "must not be capable of exceeding the 12ftlb limit" hence why a lot of rifles come out around 10.8 ftlbs, margin for error built in so to speak.

One force spent £6000 with a now sacked person to get a gun over the limit FACT stripped the gun and altered it and fed it pellet by pellet by hand ..The gun was set to take a certain pellet as its loading magazine was a proto type

Worked out how the odd pellet seemed to go the over limit after reading some old posts on here about pellet size and manufacturing tolerance. . . Think it was pianoman old post that got me thinking.

Had to much time on me hands over weekend lol so

I weighed some of the pellets in the tin and found some of the pellets h+n baracuda match (bisley magnums) 0.69g or 10.65 grains had tolerances as light as 0.67g 0r 10.33 grains in a very few with most being 0.68g 10.49gr and 0.69g 10.64gr and two pellets being 0.70g.

Tried 10 pellets of the heavier tolerance @180 bar fill for each 10 and got between 699 and 707ft per second or 11.56 and 11.82ft pound.

Tried the lighter tolerance 0.67g pellets @ got

702fps

706fps

709fps

709fps

713fps

710fps

714fps @ 10.65 gr = 12.06 ft lb but @ 10.33 gr = 11.70 ft lb.

 

Lol
