Thank you! Seems like a great forum. I know barrel length is king when it comes to velocity, but this rifle have to be what you call "a mountain rifle" fairly light weight. Im setting it up to 24, even if I do a 708 I think that will be enought power for me. My singlestack mag (tikka m55) is to narrow to fit 7saum and those bad boys, its even too narrow for 284 win, but I could make it fit with some adjustment, but 708 fits right away. Border barrels I thought they closed down, but I heared a rumour they was back again but with new owners.
