Hi All
I have been hanging around this forum since last July when I found it. It has been a great place to learn about this cartridge. Only wish I had found it before I had a rifle custom built back in October of 2006. It has a 16" SS barrel made by a local armor here in Arizona. When I speced the gun out to him I told him I wanted a 1:10 twist because thats what was called on the SAAMI drawing at the time. When he delivered the rifle a month later I noticed the barrel was stamped 1:9. I questioned him about this and was told he had talked with other armorers and determined 1:9 was the correct. At the time it did not seam like a huge issue because barrels were either 1:9.5 or
1:10 so I did not push the issue. Now it looks like 1:11 or 1:12 is the correct twist and that is a big difference from the 1:9 I have on my gun. I guess my question to you all is should I try and get him to remake me a barrel at 1:12 since I never got the barrel I had origionally requested. The rifle has a couple hundred round through it and I am gearing up to start reloading and concerned I am going to run into pressure issues and will not be able to achieve all that this cartridge has to offer. I have mentioned this issue to him a couple of times and be seemed to want to discount the information I had gotten off this board. I would appericate any advice the members on this forum can give me on this matter.
Thanks to everyone on this site, it has been a wealth of information and without it I would have been lost.
