Yep, I know I'll get ripped for this - air rifle shooting is the most practical option for keeping up a skill I learned whilst in blue (deep blue not crab fat blue). Just after some thoughts on what I "think" I may be seeing: Gents, Hope you can help me on this. Just switched from a HW100 carbine .22 to a HW100 FSB full length in .22 - using the same stock and scope, so only the metal work has changed. The carbine for food, loved the H&N FTT's and didn't miss a beat - accurate and consistent. The FSB using the same pellet had too many flyers for my liking (all the H&N's were sized but not weighed). I got a tin of the RWS Superfield, and straight from the tin the consistency and accuracy was excellent - even better once I'd sized the pellets. To myself, (RWS pellets made by JSB on a separate die) are 1 grain heavier and are softer than the H&N's - my theory goes like this: 1. The heavier weight aids in a more stable flight? Less flip when leaving the barrel possibly. 2. The softer make-up allows the rifling to engage better, thus enabling a more stable flight? 3. Any other ideas? I know that each barrel has its own preferred flavour, but surely there is physics involved? Or is it just a case of accepting what works regardless of the reasons - personally I like to try and understand some of the reasons..................... The muzzle velocity is a lowly 572 fps on average â over 60 shots it varied by 9 fps. I was looking at "flip" as a possible - I understand "flip" as being induced by the air immediately behind the pellet when it's released from the barrel. The blast of air immediately behind the skirt catching up with it? If the only air is behind it, theoretically the pellet is beyond influence. A tighter fit of the pellet to the bore should have less turbulent air passing by as it exits from the barrel and thus influencing it's flight less when compared to a looser fitting pellet as more air has passed by causing a more turbulent atmosphere around it as it leaves the bore? Would the lower air turbulence on exit of the barrel have that greater effect? Just theorizing, but beginning to lean towards the "softer" pellet base. Any ideas or advice on the above Gents?
