[QUOTE="bubbaonpc, post: 2027316, member: 92435"] I've shot/Reloaded 7-08 139-140 gr for 10 years. Trying a 120gr load for Wifey. Using H414, H4350 and RL15. Started LOW/Med loads. I should be able to get 2900 easy and up to 3200. H414 44.2gr, RL15 42gr and 4350 47gr. All are Middle Loads. New Starline Brass, Win Primers and Nosler 120 B-Tips. 4350 gets 2520fps and FLAT PRIMERS....H414 get 2720 and FLAT PRIMERS...RL15 @ 2650 Yea, you guessed it ...FLAT PRIMERS. I'm shooting .02 off lands. What is going on? If I were 400 FPS faster, I'd understand. I have NO heavy bolt lift...or other pressure signs... Seems every load..( 300 BLK OUT...6.5 Gren...5.56 Ect).. I have used Win Primers with the past 6 months has been "HOT"...not in FPS but plenty pressure signs. Has anyone else had issues with Win Primers? Maybe try CCI, Rem or Fed ?? Rifle is a Marlin X7.
