Some people might jump all over me for saying this, because I don't compete, but I do dispassionately read all their results and can see trends w/o any emotional baggage, and the only two pellets worth shooting at high speeds in a .22 are the JSB MRD (w/flyers and all) and the AEA 21.9. If you've got some old MRD's, those all day long. I absolutely love the 18.13 JSB pellets, and they can shoot well fast sometimes, but they will lose it where the other two won't. If you shoot a 18.13 between 850-900 it won't give you any surprises as you move out. I shoot my spinners at a 100y quite regularly, using them. Yeah, there's more drop and drift, but that is easily figured for, and they are my number one choice for plinking. Seeing as you are mostly going for benchrest I think that you would be better off just sticking with shooting the AEA and getting used to those, at least until/if the MRD's get back on track.
