What ftlb in fac is the 135Originally Posted by Barryg
That 125 must be big its the same stroke as the 135 but 29 mm bore instead of 30 mm almost the Patriot swept volume, is it running at under 12 ft/lbs?
I looks so far that the 135 is the worlds biggest ever springer

From what I have seen reported in countries with no limit around 24-27 ft/lbs in .22 but the .30 is way over 30 ft/lbs

I've a picture of me son with a hatsan 125 along side of him and it looked ridiculous. The 135 as mentioned is a 30mm cylinder. Handled a 30 cal at my rfd, I'd say it was unusable, made a 80 feel like a rat catcher!

Here's a question because I don't know the answer. Did the whiscombe rifles stroke number i.e 55, 60, 75, 80 refer to each individual piston's stroke, or combined stroke?
The JW80 was a genuine 30ft-lb rifle by some accounts. I'm not sure that would be possible with a combined stroke of just 80mm. So was it 80mm per piston? Which would give 160mm total stroke!
Hopefully someone more knowledgeable will chip in and correct me

The Gamo 1250 Magnum has got to be amongst the biggest with its enormous bore and stroke. Bowkett told me that he came up with a .25" version to compete with the Webley Patriot in the States. It used a SuperTen bull barrel shroud and he fitted a .25" BSA barrel. Marketing decided the pricing was against it after all the modifications were made to a standard 1250. Cost would have been above the Patriot. It was ideal for poking out squirrel dreys

You are right one of the biggest just behind the Patriot bore 29 mm stroke 118 mm the Patriot 30 mm bore stroke 114 mm but the 135 is bore 30 mm stroke 120 mm.The Gamo 1250 Magnum has got to be amongst the biggest with its enormous bore and stroke.

They quote 30ftlb for the 135 but 34ftlb for the 130 as featured in the thread how not to cock a springer

Ok not stock but higher powered than stock .
According to Rich, his rifle is just a shell of a Hatsan 135. He has completely remanufactured the powerplant with custom parts that are too exotic to explain. It uses a gas spring, but that’s as close as it gets to the stock rifle. He added a custom TJ barrel, after discovering that his new powerplant benefitted by more length.
The stock 135 he has gets 535 f.p.s. with a JSB Exact 44.775-grain dome. The custom rifle gets 625 f.p.s. with the same pellet. As far as I could tell, the cocking effort of his rifle is identical to the one I am testing for you — 57 lbs. For comparison my test 135 got an average of 580 f.p.s. with that pellet. So Rich has boosted the rifle’s velocity with no increase in cocking effort. He’s done this by means of a totally new powerplant plus a new barrel. The original 135 barrel is 10.5 inches long and the one he has put on the gun is 20.5-inches. Usually a longer barrel does not add velocity to a spring gun, but on this one it does.
38.85 ft lbs after custom tuning . He is also going to try and get 700fps from it ,that is 48.73 ft lbs.

Is that figure possible out of a springer ...??
