Hi,I have found that Napier Power Pellet Lube works very well when you follow the instructions i.e a couple of drops in a tin. we found it hard to believe but for about three pounds a bottle our grouping was consistantly better even in " a blind test".Variety of guns tested including air arms .177 410 .177 web raider .22 BSA scorpion pistol .22 ASI Rangemaster So a good variety.
Hope this is of use.

regards

Steve
