BCSteel, maybe it is just me, but the consistency you state you do not have a problem with, seems to be the problem.

A seated FT position and a seated artillery hold position sound like the same thing to me. If they are not, then certainly the group will shift. The standing position should be shot with the same hold points used in the seated position, if not the group shifts. When hunting, the same hold positions on the gun and artillery hold should be used. Consistency is the name of the game with a springer. My old Diana 34 taught me this many years ago and put a lot of game in the pan for me.

If the gun groups consistently and the shifts are as predictable as you say they are, then hold consistency seems like the culprit.

Ya, could be that when I used to shoot springers, I shot them a lot. Like 3 or 4 days per week for a couple hours at a time. Maybe I just just got into the habit of holding the gun the exact same way every time with out really noticing. 10 people saying the same thing probably means that I'm wrong. Guess I'll just have to go out and shoot more :D

Ah, that changes the picture quite a bit. Maybe I didn't read your questions well enough, but I got more of a "why are springers hold sensitive" vibe than "how can I make this particular springer behave more like my other springers" - my bad. I think this moves us more towards Chevy's suggestions for tuning the gun to smooth the shot cycle. Taming the power, buttoning the piston and adding or improving the spring guides can all help to turn the sproing into a thunk. (Or so I'm told, mine's still a sproinger and it's only 495 fps). Extra weight helps, especially if it's in the right place to put the centre of gravity in-line with the piston to reduce twisting moments during the shot. But you can never argue against more practice!

All the best,
Jim

It's all good. Most of it was on me from expecting to just jump right back into springers as good as I used to after not shooting for 5 years.

The 1" of pre-load I took out though has made a world of difference in the shot cycle though. It is much less buzz now and noticeably nicer to shoot.

The spring twang can be eliminated. If you want peak power it can be done one way (sheath/liner for the spring/piston) and be substantially quieter, or add some spring tar to that and make it silent but it'll cost you some power. Tar also tames the gun a bit so its power lost for the right reason. Still, doing it right you can minimize the power lost from the tar. When people shoot mine they think it's a nitro gun since it's so smooth and silent to cock, then shooting is even quieter than a nitro. The giveaways are it's far easier to cock than a nitro and quieter so people who know these guns can't figure out wth is going on... Even when I make it full power coil gun quiet with that work it's still easier and smoother to cock than a nitro, quieter to shoot and on average more powerful.
So try the sheath mod and or tar....

I removed the rear spring spacer and put the full length full power spring back in my Benjamin Classic. I am quite pleased with the results as I am getting very good accuracy and the power is still a step up from the non pal spring. My guess is that it is right around the 500fps with a 14gr pellet. The only thing I am going to change is to add a washer between the spring and the rear stop so the spring does not have to twist on the rear stop.

I haven't tried it with 22 but 500-550 sounds about right.
I wouldn't worry about the spring, probably doesn't twist at all but it certainly won't hurt to put a washer/bearing in there. Was there a pix named "Washer 4" in the guide showing a brass and whiteish plastic washer? If so that's how I'd do the washer, not brass but the plastic between the washer and base. It makes for a much better bearing so if you really want it to rotate then it at least give it a chance to do so.
So hows the cocking effort and firing noise level? If you had to estimate compared to full power... And overall plinking enjoyment? I think the mod makes an outstanding plinker, better than anything you can buy.

I would say cocking effort and power are right about half way between the non pal spring and the pal spring. I like the way it shoots like this, I can still shoot it in the house if I want but has more punch than the week non pal spring without feeling overstressed. I also polished the spring and moly lubed the gun and I am sure that helps as well.
