IMHO, the best pellets are those that shoot well in your guns, at the ranges you shoot, for the cheapest price.
I own and regularly shoot 8 different springers, from 375fps (slavia 618) to 1030fps with 7.5gr lead (gas ram). H&N excite econs shoot as well as premium pellets in the lower velocity guns. I shoot a lot (3000 pellets will last me a few months -I'm retired)
I buy H&N from Nikonos on ebay. Econs are $5 CDN for a tin of 500. I find H&N Sport (8.18gr wadcutter) at $7.50 per tin of 500 to be almost as accurate as their match grade. I rarely shoot from a bench so "useable" accuracy is what I look for.
Incidently, the gas ram shoots the econs surprisingly well at 1030 fps. 3/4" groups at 20 meters, rather than 1/4" at 20 meters with premium pellets. However, at 30 meters, the groups really open up. So I shoot the cheap econs in that rifle up to 20 meters. At that initial velocity anything I hit blows up. Crabapples are really fun. Squirrels fight over the pieces while the blue jays just fly away with them.
just my $0.02.
ps. I bought a tin of pba's years ago. The only gun that will shoot them well is the gas ram at 1220 fps. Loud supersonic crack and poor accuracy. The tin is still almost full.
