nderfel Posted May 19, 2016 Report Share Posted May 19, 2016 bear with me please gents, i am new to this PCP game and its been years since i picked up a springer. I am zeroing my new BSA ultra se with the pellets that came with it, RWS superdomes... Every 5th or so pellet seems to be a flier, not even a little bit but 6 inches in any direction. any ideas, I know the rifle isn't regulated but the pressure is about 150 bar after I have finished so well within what I would think would be operating limits. I have tried it with mod on and mod off, same thing thanks nick Quote Link to comment Share on other sites More sharing options...
FalconFN Posted May 19, 2016 Report Share Posted May 19, 2016 Does it the group in exactly the same place before and after the flier? If so then your scope is probably not the problem, which leaves either loose barrel/internals, worn/damaged o-rings, damaged pellets, something damaging the pellets on the way into the breech or human error. It's hard to diagnose but start by checking for movement in the barrel, mounts and anywhere else you can look. Then to rule out human error try clamping your rifle to a workbench. I would then examine each pellet and 'feel' if there is any difference in the way each pellet loads - changes in resistance or fell of the bolt. Then try different good quality pellets. If it's still not grouping then it may just need a good clean and service. There is probably a simple solution but it's sometimes hard to pinpoint exactly what it is.

nderfel Posted May 19, 2016 Author Report Share Posted May 19, 2016 cheers, i will start with the basics and see how i do Quote Link to comment Share on other sites More sharing options...
Zetter Posted May 19, 2016 Report Share Posted May 19, 2016 (edited) Also definately try some different pellets just because it came with superdomes doesnt mean the barrel suits them. Also what calibre is it as I know from experience that a lot of BSA barrel in .177 seem to adore Bisley magnums. I do have a rake on pellets in both .177 and .22 kicking around so if you want some batches of the common ones to try let me know and ill post you some save you buying loads of tins finding the right pellet for the gun.

It's as if they've skipped the sacred blessing stage, possessed by demons they are. Quote Link to comment Share on other sites More sharing options...
Sha Bu Le Posted May 20, 2016 Report Share Posted May 20, 2016 I ditched RWS Superdomes a while ago due to a similar situation. Was getting too many flyers from tin to tin. Tried a few other makes before settling for AA Diablo Fields. Also got good results from JSB Exacts. Gun is a HW100. Quote Link to comment Share on other sites More sharing options...
bruno22rf Posted May 20, 2016 Report Share Posted May 20, 2016 Another vote for AA Fields-pm me your addy and I can post you a 100 of the blighters. Quote Link to comment Share on other sites More sharing options...
figgy Posted May 20, 2016 Report Share Posted May 20, 2016 Try other pellets but check your pellets for damage before loading. Every BSA I've shot liked Bisley and Accupels the original Eley wasps in the blue tin were good for plinking too. Quote Link to comment Share on other sites More sharing options...

winnie&bezza Posted May 20, 2016 Report Share Posted May 20, 2016 do you have silencer on it?....try without.../refit it may have to get another...had exact same thing with a scorpion Same happened to me the other day. If you look down the front end on mod you might see grey marks where pellets brush the internal wall. I had two shots bang on and then a couple of fliers. Shot without mod and all was fine so bought a new mod and was good after that. Quote Link to comment Share on other sites More sharing options...
figgy Posted May 21, 2016 Report Share Posted May 21, 2016 If your mod is getting clipped by pellets drill it out untill it no longer clips only talking another millimeter or so bigger diameter hole, it will still work and saves buying a new one.

I will drop you a PM next week if that's ok? you beat me to it i have same gun i brought new a couple of months ago and get same problem though my fliers are about an inch or so from group probably 2-3 fliers per 10 shot mag, was going to put simular post up colin odd... does your action move in the stock? I was checking the obvious things earlier and there is definite play in the action in terms of being able to wiggle it slightly in the stock...

figgy Posted May 24, 2016 Report Share Posted May 24, 2016 The action should be tight in the stock. Try using strips of sheets of paper to pack it so it stays still and see if it groups better. Quote Link to comment Share on other sites More sharing options...
nderfel Posted May 24, 2016 Author Report Share Posted May 24, 2016 i have tracked my issue down to the mod... i am getting pellet on pellet groupings at 30 yards (the legnth of my garden) without the mod. stick it on and every 5th pellet or so is all over the place.... i can only assume the pellets are clipping the inside of the mod althogh i cant see any silver residue inside the mod Quote Link to comment Share on other sites More sharing options...
winnie&bezza Posted May 24, 2016 Report Share Posted May 24, 2016 That was exactly the same that I had with my groupings but had light grey marks inside mod. Quote Link to comment Share on other sites More sharing options...
hoggysreels Posted May 24, 2016 Report Share Posted May 24, 2016 Was out today doing a bit of pellet type testing etc ... tried a good few types/sizes. Struggled to get a decent grouping using any. Turned out pellets were clipping the mod. My mate (Evo) repositioned the mod and retested , problem solved. I've felt a bit under the weather lately, so a big thanks Bob for sorting things. JSB Exacts 4.51mm like you suspected was grouping well. My now pellet of choice for the HW100 kt. Quote Link to comment Share on other sites More sharing options...
nderfel Posted June 2, 2016 Author Report Share Posted June 2, 2016 How did he reposition the mod? Mine is either screwed on or off and not a lot of play in it all all? Cheers Nick Quote Link to comment Share on other sites More sharing options...
hoggysreels Posted June 2, 2016 Report Share Posted June 2, 2016 Im not one for wangging things tight .. think he was a bit more firm with it and basically tightened it up .. the pellet clipping has stopped, made up .. Quote Link to comment Share on other sites More sharing options...
