BSA Scorpion pistol (versus HW45)

[Dornfelderliebe]

Not much to do today so got the old Tenma sound level meter out in the garden. The measurements were taken 1½ feet up and 4 feet from the meter to the muzzle. dB peak-hold and A-weighted.

Scorpion pistol ~5.3 FtLb .22
101.5 100.4
With cocking aid 104.5 104.5

HW45 ~4.9 FtLb. Sold as a .22 but fitted with a Weihrauch .177 barrel.
105.8 105.9

HW80 ~10 FtLb .177
106.8 107.0

Beeman P17 ~2.2 FtLb Single pump pneumatic .177
100.4 100.9 102.3

Surprised that the Scorpion's cocking aid makes the gun significantly louder.

Not surprising Antoni, I always felt my .177 was louder with the aid.
A little while ago I managed to get a silencer adapter from Protek supplies which fits over the barrel but with a cut out for the front sight.
Then I went to A &M custom gunsmiths ( nearer to you than me) and got a Titch silencer, short and fat, and made a good job of quieting it down. all ok.
Then I asked them to let me try a twink. I've never heard anything like it. With the owner firing it All report disappeared and all I could hear was the internals and they were not as loud as we are all led to believe.
The only problem was the twink was too long but it was good.
I was told in no uncertain terms not to use their silencer as a cocking aid.
Any way got my Meteor out today and tried it with the titch and it was reasonable but fits perfectly in my Ramsbottom gun bag so there it will stay
Looks like I've got to get another titch and in for a penny get a Twink aswell.
Try and find an adapter that allows you to use the front sight

Thanks for the info re A&M. Added it to my airgun notes.

Point is, the Scorpion is relatively quiet. Least likely to need a silencer. That's what gave me the idea to quantify the relative loudnesses of my airguns. The measurements were taken fairly close to the muzzles, at neighbour distances they'd be much lower.

The loudest was the Alecto / Zoraki. I had to return it to the shop because of leakage. Excellent pistol tho. I never measured it but it was LOUD. It was a used one and came with a spring-baffle-principle moderator (Wiehrauch?). Very effective. Bit of a pain doing the travelling buying and returning it but the shop in Derby was entirely professional.

At least I briefly had the experience of using the pistol and was amazed at the efficiency of the moderator. If I ever need one I'll fire up the lathe and use that design idea. It wouldn't be my first home-made job.

Had both before and preferred the style and overall finish of the HW45. Not a fan of the big plastic grip on the scorpion and don’t think Iv seen alternatives for it but maybe I’m wrong. The standard HW45 fits colt auto grips so loads of options there and never had a problem getting it on aim. I think a loose hold was best and lots of people say to strip out the excess grease as otherwise this can cause inconsistent shooting.
I once had a version I think was called the custom combat, it had 3 barrels, a finger groove grip and a threaded muzzle. Sadly and as happens too often sold it never to see another.
