[QUOTE="PapaSmurff, post: 2506610, member: 118512"] I haven't had any problems with stabilization so far with the 177's. Like him I am firing them out of an 8" twist barrel 28" Bartlein Remington Varmint contour. Mine is throated a little extra longer than Sammi but not sure exactly how much longer; I wanna say it's around .110" longer but can't remember exactly. It is a fast barrel and so is my 26 Nosler though. They were built by the same gunsmith (Chris Brown of Long Range Customs) in Idaho. Every rifle he has built for me to date shoots in the .1-.2 MOA range. He does outstanding work in a timely manner for very fair prices. The furthest I have shot the 177's so far is to 500 yards. It's possible that they will destabilize after that but I don't know cause that's as far as I've tested them to. Like I said though mine has an extra long throat and helps with seating them out longer and burning 2 to 3 grains of extra powder before I tend to hit noticeable pressure giving them just over 3,300 fps for my accuracy load in that rifle. If I was load developing with a SAAMI spec chamber, even with an 8" twist 26" barrel then I would have chosen the 169's instead of the 177's to keep my velocity up which in turn also helps slightly with bullet stabilization issues. If I notice any stabilization issues when I start my long range testing out to my 725 yard target and beyond then I will keep y'all informed. [/QUOTE]
