I have a couple questions about barrel length vs power in a typical break-barrel springer, coil or nitro, doesn't matter.
Basically has anyone tested various barrel lengths with one gun, or noticed an pattern of power loss with shorter barrels?
Also, I know the TX200 has a shorter than normal barrel and I'm curious if anyone who owns one can give me a real #? I don't mean overall length, but the actual rifled part that the pellet makes use of.
I was corresponding with someone about it and they claimed it was 9". I thought/assumed it was closer to 15. I also believe there are two different lengths, one being a shorter carbine. Can anyone clarify their length and if it's a std or carbine? And please don't quote the mfg's specs, but actually measuring their barrel.
I personally have seen a loss in power with reduced barrel length in springers, for example a generic 18ftlbs .177 springer with an 18.5" barrel losing about 1ftlb per inch of barrel length removed. I haven't gone shorter than 13" which put the guns below 13ftlbs, but before I sacrifice a barrel I'd like to get input from others who have seen similar results using shorter barrels, carbine, cut, whatever.
The guns I used for my testing were standard Crosman break-barrel with both coil and nitro springs. I have mainly tested .177 which needs more length than .22, but I have also noticed a slight drop in .22 when going from 18.5" barrel to 17.3". Not nearly as much as a .177, and sometimes almost nothing at all which leads me to believe an 18ftlb springer in .22 only needs ~17.5". It also makes me wonder what the ideal length (for power) is in .177 at 18ftlbs, and how that would change as power went up, say 25ftlbs? I'm tempted to try a longer barrel for an 18ftlb .177 Crosman, such as a magnum barrel of over 19.5", but that's a lot of work so I thought I'd see if anyone has experience with this first.
Thank you in advance for your time..
