I use the rimfire blend but I also shoot a lot of wax coated lapua rimfire ammo and it definitely helps clean that out.
Elly uses wax, Lapua doesn't. Lapua uses a "grease" type of lube. Rimfire Blend is effective on both.
Londero and Rangeview have Bore Tech C4 Carbon Remover in stock.
Good to know. It definitely feels like a wax and seems to become a lot more liquid even with a small change in temperature and leaves yellow staining on my fingers.
