De-tuning springers.

[xp50]

Hi All.

I have a number of springers (5 in total) and as the only shooting I do these days is in the garden would like to drop the power to make them safer, quieter and easier to shoot.
I have a Meteor in .177 that is doing about 6.5 ft llbs and it is a joy to shoot. 1/2" 5 shot groups at 15 yards from standing.
I would like to replicate the action of this gun in my other guns so what are my options ?
I would rather not start cutting springs down if possible.
I was thinking of putting different springs in the guns ie a Meteor spring in a
Mercury.

Any suggestions ?

Take it easy,
Andrew.

What are the other guns?

What are the other guns?

BSA Super Meteor Mk 4 .177
BSA Meteor Mk 5 .22
BSA Mercury .22
Weihrauch HW35 .22
Weihrauch HW57 .177
XS79 (bulk fill convert) .177

I will probably leave the Weihrauchs as they are but the .22 Meteor and the Mercury are quite feisty.
I bought them all with issues and repaired and serviced them with factory standard parts.
The Meteor is doing 10.5 ft llbs and the Mercury is doing 11.5 ft llbs.

Take it easy,
Andrew.

Chambers sells German legal limit springs for Weihrauchs.

I believe that's 6ft lbs.

A HW95 at this low power would probably be very pleasant to shoot if you're only interested in informal target shooting.

With enough knowledge and internet trawling I am sure it would be possible to find lower power springs to fit ( as above Weihrauch euro power springs readily available ) but surely the easiest and quickest way to lower power is just to heat the spring and squash a couple of coils .

this could damage the guns internals due to the amount of power reduction required . he may find there is not enough preload and the spring is free to bounce about inside the gun

I assumed a modicum of common sense would be involved Fitting a spring with NO preload is not a good idea .But in my , limited , experience most springs ( especially .177 ) have enough preload to allow a bit of reduction . The exception to this is AA which are really "tuned" actions anyway . If enough coils are squashed to allow a minimum of preload most 12 fpe springers will drop to about 8-9 fpe making them a lot more "relaxed" to shoot

7.5 ft lb I think?

yes but he wants 6.5

Germans are on 7.5 Joules

Thats @ 5.53 fp



... and that's what I'd do for the German guns ... put German springs in and leave your springs for when you want to go back to full uk power.

BTW ... a Meteor doing 10.5 is quite impressive? What's the 0.177 doing ... 6.5? So 4 fp diff between 0.177 and 0.22 ?

I knew there was a 7.5 in the somewhere

[Philip W]

yes but he wants 6.5

About 6.5 he says . But what he wants and what can be achieved could be two different things

as you said you have "limited experience " so i suggest you wind your neck in , don't try and start an argument about something you have "limited experience" of and let others who do have experience answer the question that was asked .

Hi Guys.

Thanks for the answers.
I'm not specifically looking for 6.5 ft llbs. That's what my .177 meteor is doing and it has a perfect feel for a garden gun. The smoothness is what I am looking for, not necessarily a certain power.

I think I will dismantle both Meteors and compare the old spring (.177) and the new one (.22) and see the difference in length.

I know from many moons ago that just cutting coils off a spring make the gun sound like a Zebedee convention !

I think I will be leaving the Weihrauchs alone. The HW35 is smooth as you like at 10.5 - 11 ft llbs depending on pellet. The HW57 is new and not even run in yet, although I am thinking of moving it on.

Take it easy,
Andrew.

Mr Skygrowler ,

I can fully understand why you have "miserable git " under your user name Keep warm and have a good day

p.s What I class as limited experience and what you do can be , once again, two different things
