Seems like this AR is a lot more powerful than the RWS that I've used for the past few years... seemed to do a lot more damage to the critter @ 25 yards compared to what the RWS does. Is it just me, or does the Disco pack a harder punch compared to the RWS? Does anyone have any info comparing the muzzle FPE between the two with a 14.5 g pellet? _________________ RWS 350 Mag .22 Leapers 3-12X40 Gamo Shadow .177 Benjamin Discovery .22   Posted: Wed Feb 29, 2012 1:46 pm radar Silver Status Member Joined: 13 Nov 2011 Posts: 1138 Location: Des Moines, Iowa, USA Been here? http://www.airgunsmith.com/airgun_data_base/agdatabase.cgi?FA=Show+All+Entries _________________ It's never too late to have a happy childhood.   Posted: Wed Feb 29, 2012 4:49 pm rsterne Moderator Joined: 15 Jan 2008 Posts: 2998 Location: Coalmont, BC I notice on that chart the first two entries for the Disco are obviously on CO2 as they are under 650 fps.... Not sure why the other entry is so low with 14.3 gr (770) because that is NOT typical of the Disco in .22 cal.... Mine is a very typical gun, and stock out of the box it shot 800-840 fps (averaging 827 over 30 shots) with 14.3 gr pellets.... I had a BAM B-28 which is a 350 Clone, and from what I understand they shoot virtually identical.... It shot between 811 and 864 fps with a variety of 14.3 gr. pellets, with most averaging right around the same as the Disco.... I would say that for all practical purposes they are the same power....

It was recommended to me not to exceed an 18 grain pellet in the springer... is this the same with the PCP? Would a 22 grain pellet be too much for the Disco? _________________ RWS 350 Mag .22 Leapers 3-12X40 Gamo Shadow .177 Benjamin Discovery .22   Posted: Wed Feb 29, 2012 7:35 pm rsterne Moderator Joined: 15 Jan 2008 Posts: 2998 Location: Coalmont, BC In stock form, the Disco is best with pellets from 14-18 gr.... You won't harm it in any way with heavier pellets, but the velocity will be down.... Good for larger animals at close range, though....

Try the 24.39 (or is it 25.39?) grain JSB Exact Monsters. They shoot less than 700 fps, but hit like a brick. My disco like them. _________________ It's never too late to have a happy childhood.   Posted: Thu Mar 01, 2012 6:06 pm domer_pyle Senior Member Joined: 17 Sep 2009 Posts: 523 Springers - heavy pellets = less fpe & fps - light pellets = higher fpe & fps PCP - heavy = higher fpe & less fps - light = less fpe & higher fps The weather has been terrible since I got my chrony so I can't confirm my stock Disco, but when my first one was stock it started at 860 ish and peaked at 870 something with Premiers. That was on a chrony I'm finding now was a bit off though, but everything I put in ChairGun said I'd have a 21" drop at 100 yards and guess what. It was spot on   Posted: Thu Mar 01, 2012 6:49 pm NZ Shooter Suspended Joined: 17 Dec 2011 Posts: 146 Location: Dunedin, New Zealand Lighter pellets producing higher FPE in springers ?? Hmmm. Is that not a slightly misleading quote ?? I'm no rocket scientist, but I think that would only apply to a specific comparison at any given time. I.E. firing Raptors ( 9.8gn ) in my Patriot would ( apart from being a bad idea ) produce a higher MV, yes, but at 1145 fps, would produce exactly the same FPE as using 15.43gn ProMags @ 900 fps. Yes, using too heavy a pellet can slow the MV to a point where FPE suffers, thus making the initial quote true. So I guess my point is that lighter pellets producing higher FPE can be true, but not in all cases. _________________ Webley Patriot .22 @ 28 fpe Nikko MountMaster 4x40 AO   Posted: Thu Mar 01, 2012 7:26 pm rsterne Moderator Joined: 15 Jan 2008 Posts: 2998 Location: Coalmont, BC My experience with springers is that they tend to have an ideal weight range of pellet of several grains.... with lower powered guns doing better with light-medium pellets and magnum springers prefering medium-heavy pellets.... If you go too light or too heavy, the FPE drops off.... Bob _________________ Dominion Marksman Silver Shield - 5890 x 6000 in 1976, and downhill ever since!

Ideal weight range is a good call, aside from possible damage going too heavy or light in a springer, there is a sweet-spot in every power class. Experimentation is good ...... _________________ Webley Patriot .22 @ 28 fpe Nikko MountMaster 4x40 AO   Posted: Thu Mar 01, 2012 9:18 pm radar Silver Status Member Joined: 13 Nov 2011 Posts: 1138 Location: Des Moines, Iowa, USA My particular example of the RWS Diana 34, .22, peaks at an even 18 fpe average with JSB 18.13 gr.-- CP 14.3 gr. get 17.53 average fpe--25.4 grainers are down below 15 fpe. domer_pyle wrote: ...That was on a chrony I'm finding now was a bit off though... How so? I never seen anything as consistant as a Chrony F1 unless the lighting is wrong. I have 2 of them and they read 1/3 of one percent of each other, which is probably the gun's variation in the shot strings--not the Chronys'. I notice they will read a bit high if you are using them indoors with a strong single source light above it because the lines of light make the sensors the base of a triangle, and the higher the projectile passes above the sensors, (or the lower the light source) the sooner it breaks both sides of the light triangle. Now I kill any stong overhead lights and use a separate battery powered LED light for each sky screen when indoors. Also, they don't like the flicker of fluorescent lights. _________________ It's never too late to have a happy childhood.   Posted: Thu Mar 01, 2012 9:59 pm NZ Shooter Suspended Joined: 17 Dec 2011 Posts: 146 Location: Dunedin, New Zealand Wow 25.4's in a springer, wouldn't that make the piston rebound ?? It'd kick like a mule pushing out that much weight would it ?? _________________ Webley Patriot .22 @ 28 fpe Nikko MountMaster 4x40 AO   Posted: Thu Mar 01, 2012 11:36 pm radar Silver Status Member Joined: 13 Nov 2011 Posts: 1138 Location: Des Moines, Iowa, USA NZ Shooter wrote: Wow 25.4's in a springer, wouldn't that make the piston rebound ??

It even feels like it's being damaged firing 22+ grainers.... so I only fired 5 or 6. _________________ Webley Patriot .22 @ 28 fpe Nikko MountMaster 4x40 AO Muzzle energy difference between RWS 350 .22 and Disco .22     Air Gun Home Forum Index » Rifles You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum All times are GMT - 5 Hours   Page 1 of 2   Goto page 1, 2  Next All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First  Select a forum Main Forums----------------AirGunHome Q&AGeneral Air Gun Questions and TopicsPicture GalleryTarget Shooting: Casual, Fun and CompetitionHunting, Pest Control, Varminting People/Events/Airgun Issue Discussion----------------Introduce YourselfThe BS TopicClubs/Events/Regional/Political Airgun Issues Maintenance, Modification and Reviews----------------RiflesPistolsAntique, Collector and Novelty AirgunsBB GunsPellets/AmmoOpticsAccessoriesAirgun Smithing Buy, Sell or Trade Forums----------------For SaleWant to Buy   Note: If you are seeing "Please enter your username and password to log in."
