I just put in a TBT kit with short stroke in my TX mk3. It has lowered my energy to 10 foot pounds but it's so nice to shoot. Is that enough for Hunter Field Target or do I add a power washer to get it closer
Thanks

Air Arms 10fpe enough?
- Thread starter drsquall
- Start date
In ideal conditions (indoors, no wind and no temperature variations). Should be no problem.
However, in the "real" world, at 10 FPE, just know that for targets past 35 yards, your ranging, your drop and your wind read needs to be spot on. Most springer Hunter FT that I heard about are shooting above 12 FPE (13-16 FPE?).
If it was me, I would try out that rig in competition and practice at home to see if I'm able to adjust under varying conditions (temperature and wind).
I think confidence in your equipment and the ability to adjust will be factors in determining if you want to stick with 10 FPE or make some changes. Historically, there have been shooters using FWB 300 to compete after modification to 9-12 FPE? (per Google search, not sure if it's accurate, I suspect it's closer to 8-9 FPE)
I assume you put new breech seal, new piston seal in there ...maybe the new set up just needs to break in and then it'll pick up some FPE. Log book helps in tracking any changes or how many pellets before it breaks in... or wear down.
Can't remember the TBT kit...with it short stroked...is there still room for a power washer or is it almost spring bound?

No there is room and I did add one power washer. I did not change any seals they all looked good. I added the washer because after about 40 shots speed was at 703 average. I just shot a string with the washer and average is 746, es 18 st 4. At 10.43fpe. I going to shoot it for another 50 or so and see if I need to add the other washer.

This 30 shots of sticks and bucket at 25yds so I did chrono after those 30 average is 727 with the power washer I added.

I'm going to give you a piece of advice that I personally would ignore (cos I'm stubborn and OCD).
Your FPE are soooo close to that golden range (10.75 to 11.5 FPE) that I would Just practice for accuracy and not worry too much about FPE at this stage.
Shoot for accuracy at 40-55 yards. If you see nice groupings, I would leave the rig alone and learn to adjust.

very nice grouping at 25 yards.
oops forgot that you are not WFTF piston. Strike that golden range comment. (tough getting old and forgetful)

I added the other power washer and will see how it does. If I'm not satisfied I will just put my Macarri spring back in and try the short stroke with it. It was at 11.8 without the short stroke kit. I would be fine around 11fpe. I will say it is a totally different shot cycle, quicker and faster lock time.

Well, I added the 2nd power washer and after 30 shots my chrono results for a 10 shot string
Average speed 762
ES 11
SD 4
FPE at 10.88
I am going to run it there for a bit and try to get almost another tin through it and see how it settles. If it will stay around that I'm good with that. I got a match next Saturday so we will see.

I think you will be fine. Shoot a bunch of pellets and get familiar with the ranging. If your rifle is consistent and you do your part then you should not have a problem. Also in theory after a couple of hundred shots the speed should pick up a little

I shot an FWB300s at a couple matches and watched quite a few pellets arc into the paddles on 45+ yard targets and not make them fall. That was a 6fpe gun, and I had that problem at two different clubs.
I used to shoot an HW50s at field target matches and if I hit the paddles, target would go down. That gun is just a hair under 9fpe.
I've also shot a 1720t at a couple different clubs pistol matches. It is also in that 9fpe realm. One of the clubs uses pistol specific targets but the other uses normal rifle targets. Again, if I hit the paddle, target goes down.
Can't say that it's the same at all targets at all matches across the country, but for the 3-4 clubs where I've attended matches, 9fpe would make targets fall as they should, and 6 fpe was insufficient on the further targets.

My HW97 has a Maccari UK kit with TBT 8mm short-stroke spacer and produces about 10.5 fpe. I recently tested some 8.4 grain pellets out to 50 yards. I did not have my wind meter but I estimate it was 3-5 mph with direction changing at times. From 10 o'clock the wind was enough to push some shots 2.5 inches.
To gain a few fps you could try to remove the short stroke spacer.

I have mine stock save one 3mm steel washer in front of the top hat. Mine is shooting about 14fpe with AA 10.3 Field Heavy. If I do my part I am pretty happy.

Power level isn't critical unless you are shooting where there is a class or legal limit. I would choose the 8.4 gr pellets because your trajectory will be flatter. Yes, maybe more wind sensitive, but so what. All pellets are and you will have to learn how to compensate for each one.

I understand. I do not shoot hunter field so the trajectory drop in not an issue for me. I am using the ranging in my Vortex Diamondback 6-24X50 so the slight increased arch in trajectory for 10.3 has not been an issue either. But as I typically shoot 50 to 100 yards the drift is more pronounced than it is from 10 yards to 50 yards, so the 8.4's at that shorter range I would agree with as it is one less thing to have to be as precise about.
