[QUOTE="Weatherby Fan, post: 1698452, member: 29953"] Glad you asked, I sold the Stiller action and built a 2nd 300 PRC on a Kimber Montana 8400 (300wm) donor, I liked the first one we built on a Kimber Montana so much that I just went with the Montana again. Trued and squared the action Extended the mag box to 3.7[I]5"[/I] Lightened the factory trigger to 2.5lbs 26" SS #4 Fluted, 1-9.5 twist, 5R Benchmark Barrel 2 port Brake added Factory Montana Stock, with palm swell and high comb added Talleys holding a Zeiss V6 5-30x50 ZMOA scope With the scope rifle weighs 9lbs 1.5oz So far both factory Hornady loads shot 50-60 FPS faster than advertised velocity 212 ELDX adv vel 2860 avg vel 2912 3/4" groups at 100 yds 225 ELDM adv vel 2810 avg vel 2865 5/8" groups at 100 yds Did a string of Hornady 230gr A-Tips and R26,215m primers, started at 75grs and went in 2gr increments to 76.6 and had a node at 76-76.2 so went with 76grs and is averaging 2898 fps with the 230gr Atips I have since added a brake to the rifle so hopefully get to the range in the next few days.
