Ryan Pierce of Piercision Rifles also recommends Boretech Eliminator and Remington 40x. I bought one of his 28 Noslers from another member and was having accuracy issues. Called Ryan and asked what to do. RL33 is very dirty and told me to clean with Boretech first then scrub with 40x then oil. Scatter groups went to one hole groups. Good luck.GA Precision recommends Bore tech. I bought some. Doesn't stink and extremely effective and easy application tips. Win win. They have for break in an individual carbon and then copper. That is for a derp clean. Then eliminator which is carbon/copper for regular use. The other thing I love is their proof positive jags and brush so you know if you get green then it's your barrel and not the jag as well. Hell I should be sponsored.
