[QUOTE="Fiftydriver, post: 113603, member: 10"] Keep one thing in mind, while the 1-8 twist would be correct for a 243 with the heavy VLD bullets, when the time comes and you rechamber it to the 6-06, you would tear apart most 105 to 107 gr bullets with the 1-8 twist!! For the large 6-06, a 1-9 is vastly superior for use with bullets such as the 105 gr Berger, 105 gr A-Max and 107 gr SMK. My question to you is why wait to chamber it in 6-06? That is additional cost of dies and brass and such. Add all that in and there would be little difference in just setting the barrel back 1" and rechambering when the time comes. Basically what you would be doing with your original idea price wise. I would also say that the "6 contour at 30" is not an overly heavy barrel. If you want this weight range of barrel I would strongly look at the #7 contour and have Dan flute it with its heavy 50 BMG style flutes. This will produce a finished barrel weight a hair less then what a non fluted #6 would weigh but with the vast improvement in barrel rigidity. The 6mm rounds are not overly stressful on barrels but why not get a stiffer barrel if you can for the same weight? Just my opinion. If you go with a 30" pipe, I would not mess with the 243 or 6mm AI, go straight to the 6-06, buy one set of dies and set that barrel back a couple times when needed and life will be good. Order a 1-9 twist 6 groove barrel, no 3 grooves, thin jacketed heavy 6mm bullets DO NOT like 3 groove barrels at anything over 3200 fps in most cases and you would have far more gun than that. A 1-9, 6 groove would perform very well offering you full performance with bullets such as the Berger and Hornady. Just my opinion, Kirby Allen(50) [/QUOTE]
