I can give you some of my "heavies" to try in it too Steve? Tbh the drop after 30yrds didn't bother me too much as I'd only previously shot .22. My "old" s400 loved em although the current batch I've got aren't quite as good as the others I had (and used up)!
Rick Ardern. RIP mate, never ever forgotten!
