[QUOTE="knc1105, post: 548956, member: 23577"] Mine liked Retumbo and 200 gr Accubonds. I had my bullets Boran Nitride coated by Superior Systems Systems.com I was worried about barrel heat and wear and throat erosion. The Boran on my other rifles has extended barrel life a bunch. In fact I have not replaced a barrel since I started shooting Boran on all my rifle bullets. It does keep barrel temp way down. My 300 RUM is a 700 Police which is a heavy (.920) barrel but my custom 338 RUM is a #5 profile Lilji barrel. I need to take a infrared temp gun, but to the touch my 338 is approx. the same same temp after 5-slow fire shoots with Boran than it is after 2-naked bullets. Superior is so busy moly coating bullets for Sierra that they have quit coating for the public but they offer a complete kit with their propritary Boran mix and you can do it yourself in a large tumbler. It's more convienent and is alot cheaper, you don't have to wait for service, and you save shipping bothways. [/QUOTE]
