It never hurts to ask questions. More often than not others might have similar inquiries, so responding to posts like this is often helpful to more than one individual. Being honest about different platforms being used along with the types of projectiles goes a long way in assisting folks trying to figure things out. Please remain kind and respectful to our fellow air-gunners, we are all part of one community.
Some of my final thoughts on this thread (for entertainment, mostly redundant ramblings). Not necessarily directed to the OP or anyone in general...
Pellets are fantastic and horrible projectiles all at the same time. Compared to even 22lr, most pellets have a horrible BC. Being drag stabilized helps with short range accuracy and somewhat makes pellets safer projectiles. In case a shot ever misses its mark, I'm more comfortable knowing a pellet will drastically lose energy as it travels downrange, even though shots are taken in a safe and controlled environment. Can't say the same for bullets, slugs or other conicals. For the same reasons bullets, slugs and conicals retain energy/velocity over further distances they also handle wind or random gusts much better. On days when the air is dead calm pellets are capable of amazing accuracy, otherwise you're better off with a different projectile or just accepting reality.
Springers can be difficult to shoot, especially if over sprung. You're using a piston to rapidly compress air, there's going to be several movements before the pellet even leaves the bore. I'm not even going to get into possible harmonic issues that can occur caused by internals, lubes or barrel accessories/attachments. Most break barrels have a solid and repeatable/consistent lock up, generally this isn't an issue. I prefer fixed barrels myself, but more for their added weight contributing to a more stable platform while shooting from a bench. Spring guns equipped with a sledge system, otherwise known as "recoilless" springers help a bunch in the "consistency of accuracy" department. My experience with a couple Diana 54's has proven them to be easier to shoot accurately on a more consistent basis, but from a mechanical standpoint I don't consider them more accurate than any other quality springer. When pushing the range beyond 80 yards you'll definitely see a difference between a springer, pcp and powder-burner. Even at 50 yards I don't believe I've shot better than 1MOA with any airgun, and the few times I've shot roughly half inch groups at 50y, I attribute those to luck rather than skill. On average I figure if getting about 1" give or take a .25" (@ 50y) I'm having an excellent day.
Lastly, there's cost. As mentioned previously, springers don't need support equipment to function which helps in some regards. At the same time, they can be awfully expensive for the higher tier options. Personally, I like the better fit & finish, triggers and parts availability of higher tier springers... BUT I've had a few budget friendly spring/gas piston rifles that delivered surprising results. I suppose this depends on getting a good example of a certain model. Believe it or not, I have a Gamo that can hang with Diana and Weirauch rifles in terms of accuracy. Yes, the fit and finish, materials used and trigger all leave some to be desired but if you hold your tongue just right, it'll print some very respectable groups. At half the cost of top tier options there are some compromises and support is lacking (aside from exchanges during the warrantee period) but if you know this going in and can repair yourself, it's not that bad. Same could be said for Crosman, Benjamin, Hatsan and similar options, just know these aren't 'match grade' offerings and might need some TLC to obtain their full potential. Then again, what percentage of Weirauch's are just shot in factory form? Mostly it seems folks get them, check for function and then tear them down for a rebuild. Kind of silly for a $400 to $600+ pellet gun if you ask me. (Yeah, I know they're pretty sweet after a tune, but I'll personally shoot them until something fails, unless detuning for specific needs)
A few questions I have, who all is shooting pumpers at 50 yards? (or better)... On a regular basis? What results are you getting? Have you developed Pop-eye arms? What model are you using to do so?
If you've made it this far, thanks for reading.
