Just spent half hour washing and lubing 2 mini batches of 80 pellets each for a little test session tonight. (JSB Exact 4.50 and 4.51) Looked at the skirt of each pellet before they got lubed, all seem to be round with an even land, not sure what else I should be looking for? Not quite got round to weighing the pellets yet, as the above did make a difference on my old rifle, so will go with it. Is this normal for Benchrest? Or do I need to be weighing them as well? Not sure if any top BR shooters will give many tips away, but will try asking nicely, please Thanks!
