Hi Tim,
well, i was half way through typing a massive post, on my phone on my break at work, but then it decided to reboot itself
so basically with my 95k i have tried 4 pellets.
bisley magnum just for chronoing it mainly and a quick group at close range..
h&n ftt which are pretty consistent and give nice groups
daystate Li, which have about 30 fps spread in 10 shots, and like yours group 'like a shotgun' ... well not quite but its hard to get a 2p sized 5 shot group at 35 yards...
then theres jsb exact 4.52, which quite frankly, it loves
only 12 fps spread over 10 shots
