Used them in .243 95 grain at 2950fps (43g of Vit 160). Very accurate and very good on Muntjac, Roe and Fallow. Now use the equivalent bullet without the CT (combined technology) lubalox coating, Nosler ballistic tip hunting with purple tip because i can find no difference in performance what so ever, even 1st shot cold barrel, perfect. I also clean if i take 1 shot or 20 so the easier cleaning thing is insignificant. They are also £22.50 for a box of 50 instead of £31 ,or there about, for coated.
