Best twist for 6BR

[rick983]

I'm putting together a 6BR rifle and plan on using a Shilen barrel. I will be shooting Bart's 68 gr. bullets and was wandering what twist would give me the best results. Also, what would be some really good loads using 133 powder. Thanks in advance!

Rick, if you plan on staying with bullets 70gr and lighter, I would do it in a 14 twist. If you think you'll want to shoot heavier bullets, I would go with a faster twist. What do plan on using this gun for? That'll help in determining the right twist for it's intended purpose.
As for loads, there are many good loads for powders in the heat range of 133.
I have had good luck with 133,322 and 135 with the light bullets.---Mike Ezell

Mike;
This gun will be used for informal benchresting at the local club and possibly a Dakota prairie dog hunt next spring. I have used Bart's 68 gr. pills in my 6PPC with incredible results and wanted to use the same bullet in the new gun. I won't be using anything heavier than the 68gr.
