JSB MRD's...I know I'm late to the game

Been working on a tune for my Wildcat 22 for pellets and found the heavy liner doesn't like 18gr pellets. Then I tried 25gr MRD's and wow! things started to really look up. I've read a bit on here about them and they like high speed, over 900fps, preferably more and they still shoot at 100 yards. I know, at least some will question this, until they try them.

I was mulling over ballistic calculators with this pellet and fast twist barres, ie 1"18 ish. It kind of makes sense, that if a pellets loses velocity faster than it loses spin, it get all wonky at long distance. BUT, if designed properly and shot fast enough to still retain forward speed, then it is better off at long distance than say a pellet that is shot at 875fps and loses a ton of velocity at 100 yards while the spin is still quite high.

Long way of saying, get the velocity up and the spin will not be excessive at distance.

These are really cool days to be an airgunner, that's for sure. I know the pellet has to be designed correctly, you can't just increase the velocity of any pellet high enough that it will work like this. You also need weight, that makes sense that the MRD's aren't like say 18gr or whatever. Interesting stuff.
