Thread: 300 wsm Tikka T3 AR2209

Im using 208s in the 300 wsm finnlight tried 2209 didnt like it, RL22 and 17 was ok , am using 2213 sc works good loaded to lenght 2.940"which fits the mag its the slower of three but by all accounts its temp stable .Im dealing with a big jump but A max shoots well enough, sc powder is not overly fast seating closer to the lands would help that ,im thinking i may cut the front section of the mag down to just above the latch openning - then dia grind 1 mm form the metal work would alllow a couple more mm longer in seating to play with .. The N550 has had the best results with the lighter 165s grn for me ..
