Are you saying that shortening the barrel from 22" to carbine length you will loose 2ft.lbs m e? I thought it was the other way. Shortening the barrel gave you a slight increase in velocity.
I seem to remember an article in AGW in the 1980s where they did a comparison between the standard length barrel '35 and the Export 22" and all the velocities in the longer barrel were lower.
I may be wrong. (My wife says I often am )

Nah! Its because I couldn't reach that high. I suffer from Dwarfs Disease. I bash my arse when I get off a tall kerb. 4'12" in my high heels. They cant pile sh|t any higher!
I cant reach to photo a std length barrel http://smg.photobucket.com/user/Airs...ml?sort=6&o=57 Anyway we should all know what a '35 front sight looks like.

Hi Ian
I think I misread T20 post thought he was moving from .22 to .177
Last year I bought a hw35e of a mate he had done a nice home tune
On it
It came with a 13ins barrel fitted and was putting out 9.5 ft lbs
It also came with its original .22 barrel .i actually prefer springers
In 22 so I changed them over which gave 12.3 with hobby pellets
The lad I bought if of said he had a standard 19 ins barrel he would
Like to swap for the .177 so the deal was done I then swaped the
.22 barrels over expecting as you said to get a rise in ft lbs but
To my pleasant supprise it gave 11.8 at no time was the power plant
Touched this was on a 1986 gun I have another 35e 1978 that
Struggles to make 11.2 both these rifles have square section
Airsporter springs with a thick piston liner and are as smooth as
Silk to cock

I have found, in a variety of spring rifles (HW35, 80 and FWB Sport) a change of calibre usually involves a change of m e by approx 20% the .22 being more efficient.
