I don't mind a little experimenting so I started to use monolithic bullets (unbanded) in my bad weather drilling. The ammo is Lapua Naturalis, the "enviromental champion", and the drilling a dark bored Krieghoff 8x57IRS from the early 1950s. So far they like each other, accuracy wise. As for the longevity, time will tell...

With kind regards,
