.                            .25  caliber  webley  patriot  quattro

.             this is the largest mainspring i have ever worked with.  must have a very good spring compressor to tune or repair these beasts.   considerably heavier and larger than than the english-made patriot/kodiaks, but a bit more powerful.   830-840 fps w/ 20 grain ftt/fts pellets after lube-tuning.   i generally use only stock parts when i lube-tune airguns.   chrongraph readings are from an untuned, un-lubed factory-direct turkish patriot staight from box after 100 shots at elevation of 750 ft above sea-level and non-sized ftt's directly from tin.              - raneman.        - 10-11-13.  ......
