My experince with recoiless springers is mainly with a 6M & FWB65 & is that H&N Match were pretty good, Hobby were not far behind & better than some of the other Match pellets I tried in them. All of this was single handed grips at 10m.
Just wondered what you might think about two handed v one handed shooting with a recoiling springer. Single handed is tiring but its not unstable in as much as it is possible to shoot very small groups single handed with it with recoiless pistols at any rate. I wonder if two handed grips with a recoling springer introduces an extra varriable into the equation making it harder to achieve a 'repeatability' of technique with some pistols being very sensitive to hold.
Dont really know if it was me or not but I could shoot better groups with a LP53 single handed than with two, but maybe it was lack of practice on my part.
