[QUOTE="Capt RB, post: 1247104, member: 85987"] The difference in my 243 and my dad's 6mm in performance is next to nill loaded as they are. My 243 has a torched throat. His is still fairly fresh. Round count would be more through his than mine as he's retired and shoots much more often than me. Biggest difference is neck length. I know that the 6mm at the speeds we shoot is not topped out and that plays a big part. After reading many articles on the subject and seeing these guns act in a way consistent with this line of thinking. I have to say that's the way I see it. As far as throat as the only acceptable answer for longer barrel life. After reading about the 6mm competition's use of H1000 extending accurate round count. I started using that in a 243ai I have. Round count is 400ish and it was built to shoot the 105Amax. It looks far better than the kids rifles at about the same round count in 243. H1000 is well documented to have this effect. However the 40 degree shoulder does have an effect on the flames path that is a positive vs a negative as well. At the rate I'm going the AI won't be shot out and I dunno if I just rebarrel the 243 to another ai but in a 10tw or not. [/QUOTE]
