At one point I did consider selling of the pellets, but then thought they would be fun for my 20-25 yard backyard range. Buying an XS-12 or CMP 853 seems like the next best option, that can also get the 10 year old son engaged into the sport/hobby.
Short stroke extensions are also available separately
Hector, Do you have a short stoking piston or seal extension available for the 48? Simply putting in a "soft" or "short" spring would tend to slow down the piston, and make the rifle harder to shoot well. The longer "lock-time" would be great for forcing one to learn proper follow through; but it might also prove frustrating.Yes; reducing the muzzle velocity from 1150+ FPS to perhaps 950 will eliminate the cracking noise, but that would still be overdriving light wadcutters for best grouping ability - so part of the equation is, asking what the target velocity might be? Even 850 FPS may be a bit fast, if one wants them to group well at 25 yards.For the original poster; a piston seal extension made from light weight material (aluminum or plastic) would reduce the effective stroke length, restoring "lock time"; when used with a weaker spring. See video below.Anyway, my suggestion is another wrinkle that is really just a subliminal message: Buy an HW30 and be done with it https://www.airrifletuning.com/contact/https://www.airrifletuning.com/product-category/tbt-tuning-kits/diana-rws/48-52-54/QuoteShort stroke extensions are also available separately
I may be wrong but isn't more involved than adding an extension to short stroke a side/under lever spring gun? I don't think it is as simple as a break barrel...
The other half is restoring the cocking arc length, so that the peak cocking force can be brought down.
Hector,Assuming the stock spring is used; simply adding a spacer to the piston nose does not affect the peak cocking force, nor its location in the stroke - think about it for a second.
