[QUOTE="brianwinzor, post: 160200, member: 1067"] My test was done using Win cases and Rem 91/2 primer, and I have no need to neck turn the cases as the chamber is about .255. I usually set my chrono at 10 feet from the muzzle, so the differences in temperature, barrel length, and height above sea level, between your circumstances and mine would only account for about 75 - 100 fps at the most, so your barrel is definitely a quick one. The first 22/250AI that I built in 1972 (Shilen 27 inch 14 twist barrel) would crank the Hornady 60 grain HP out at 3,782 using 46.0 grains of Norma 205. My current rifle struggles to reach 3,600 fps using the 60 grain bullet, and as it was chambered by the same gunsmith, it highlights that each rifle can give varying results. [/QUOTE]
