robwelsh 354 Posted January 19, 2013 Report Share Posted January 19, 2013 If your .20 barrel doesn't like h&n 11grain pellets, an have to use 13 grain, does the trajectory go like a .22 13grain pellet being shot? If that's the case, is it better to go for .22 due to more pellet choice? Cheers Quote Link to post
Acuspell 329 Posted January 19, 2013 Report Share Posted January 19, 2013 Bisley Superfield also a good pellet (if it suits your barrel) 11.4gn my Taunus happens to shoot both FTT and Superfield exactly the same. I prefer the Superfield for hunting. Just a personal thing. Accupell are also available in .20 The thing is, there will be a good pellet for your rifle and it is easy enough to find which one. .20 the same weight as .22 will still hold higher - at 100 yards two IDENTICALLy tuned rifles (Rapids shooting 950 fps) one was .20 the other was .22. The same weight pellet (Crossman premier) and the .20 hit a good 5" higher with the same point of aim and zero distance. This serves to illustrate there is a benefit to the .20 in terms of arc of flight. What rifle? Or rather what barrel - all my Theobens, ram or Rapid, shoot FTT well in all calibres. You might have a rogue, but there is a good correlation there! Quote Link to post
paulus 26 Posted January 19, 2013 Report Share Posted January 19, 2013 i always used logun penetrators in my fac .20 rapid 15.6gr but it was getting more difficult to source them Quote Link to post
robwelsh 354 Posted January 19, 2013 Author Report Share Posted January 19, 2013 I haven't changed it over yet..20 barrel etc seems a right pain in the arse to source..where's best to buy new? It's for a rapid sub 12:, cheers Quote Link to post
Buster321c 1,010 Posted January 19, 2013 Report Share Posted January 19, 2013 To change you`ll need probe , mag , and barrel . Depending on what barrel you have now , and what you replace it with , you`ll have a power difference . Quote Link to post
robwelsh 354 Posted January 19, 2013 Author Report Share Posted January 19, 2013 I know what I need, an the power bit is sorted lol just trying to source the parts. Where could I get the probes from buster? And barrel new? I'm not bothered about the mag, that I don't need to shoot like..cheers lads Quote Link to post
Buster321c 1,010 Posted January 19, 2013 Report Share Posted January 19, 2013 Chambers or Knibbs . Rapid air weapons for the probe . What length barrel you got now ? Quote Link to post
Buster321c 1,010 Posted January 19, 2013 Report Share Posted January 19, 2013 Just swapped mine all over yesterday , 12 inch barrel .20 , mags and probe . Im lucky enough to have a custom shroud being made for it as well . Not had time to run it much as yet , but seems ok . Quote Link to post
robwelsh 354 Posted January 20, 2013 Author Report Share Posted January 20, 2013 Std mfr skinny 16" bust. It's accurate..but had a go of a .20 cal mk1 today, feck me...I love it lol il be happy with 16mm 14-16" barrel mate tbh. How much are the probes? Would I need reg tweaked? Quote Link to post
Buster321c 1,010 Posted January 20, 2013 Report Share Posted January 20, 2013 You can do it either way Rob . If you get a barrel the same or longer its gonna be m.20 so more powerful BUT , with the reg set for a 177 , it will be super consistent for .20 so i left mine as it is . Hammer load can be adjusted , amongst other things , to get you where you wanna be power wise . I think Dave had 2 .20 probes for around £20 from america . Dont forget the skinny is like that for shroud volume , so there may be a louder report from a .20 . Quote Link to post
robwelsh 354 Posted January 20, 2013 Author Report Share Posted January 20, 2013 cheers buster, top man! im just going to go with a 16mm barrel mate and a hw silencer me thinks just need to get everything together, organise with someone of special talents to machine the barrel lol if i bought a 23", and had it say 14", what would i be able to do with other 9"? is it just scrap ? hopefully i wont need to touch the regulator atall, and just adjust it by other means il have to give rapid air weapons a email, atb butt Quote Link to post
Acuspell 329 Posted January 20, 2013 Report Share Posted January 20, 2013 You might be as well buying a second Rapid - 12/200 and fettle it. Unless you sell the current bits to help offset. Glad you like the .20 - I have been using it almost exclusively since 1996. I keep telling people, but many are still wary of it. For sub 12ft-lbs and not pure target shooting I cannot understand anyone using anything else. Even at 925fps it is still a phenomenal calibreand I would have it over .22 at that velocity unless the size of quarry dictated heavy projectiles. Quote Link to post
robwelsh 354 Posted January 20, 2013 Author Report Share Posted January 20, 2013 yes i agree, it is much diffrence lol i know some one selling a old mk1 .20, with ags scope, 600, no offers. i think thats pretty steep myself when i bought my mfr for that Quote Link to post
