[QUOTE="Juergen, post: 2245951, member: 118398"] I couldn't pursue this thread for family reasons during the last three month. I just repeat the list from post #1 and add the twist rates of the calibers: [LIST] [*].25-06 Rem. - Twist 10" [*]6.5 x 47 Lapua - Twist 8" [*]6.5 Creedmoor - Twist 8" [*]6.5 x 55 SE - Twist 8.66" [*]6.5 x 57 - Twist 7.87" [*]6.5 x 65 RWS - Twist 7.87" [*]6.5-284 Norma - Twist 9" [*].270 Win. - Twist 10" [*]7mm-08 Rem. - Twist 9.5" [*]7 x 57 - Twist 8.66" [*]7 x 64 - Twist 8.66" [/LIST] This is the list of barrels that I can buy for my Roessler Titan 6. Other calibers are not supported. Basically it is possible to order another twist rate, but I encountered a lot of problems and so it seems to be better to take a "standard" twist rate. 7mm-08 Rem. was one of my favourite calibers but the twist rate is to slow. Same with 6.5-284 Norma. So I looked at 7x64. A typical old german caliber for hunting. Of course one of my requirements are not apply with 7x64: "not more recoil than .308 Win.". But I can load it softly and there are a lot of advantages: [LIST=1] [*]A lot of bullets betweeen 120 and 195 gr are working with 7x64. (7mm-08 Rem. with 9.5" twist is not suitable for heavy bullets) [*]working good with lead free solids that are longer [/LIST] and it fits nearly all of my requirements that I repeat again: [LIST] [*]not more recoil than .308 Win. [*]same or better precision than .308 Win. [*]working good with lead free bullets [*]much less wind drift than .308 Win. [*]much flatter trajectory than .308 Win. [*]reasonable barrel wear [*]more power than .308 Win. beyond 300 yards [/LIST] My crucial questions is: [B]What's about the precision of 7x64 ? Can I shoot hole in hole as with .308 Win. at 100 yards ?[/B] (Of course with handmade reloaded rounds.) Has someone of you an answer to this question? If 7x64 satisfies my requirements on precision I would buy a 7x64 barrel first and one of the 6.5 barrels later. Thanks for all comments! Jürgen [/QUOTE]
