[QUOTE="wildcat455, post: 1438779, member: 102653"] fisherman983, Retumbo got me to 3187 fps at 66 gr. I moved to RE33 and hit my velocity numbers for my 264 win mag and for my 338 Lapua. Soon to try it out in my 300 win mags. Here are the powder charge work ups I did. 143 gr ELD-X Win case Fed 215M primer Loaded 2.750" BTO for .010" off lands These were new never fired cases. 72 gr 3071 FPS 73 gr 3181 FPS 74 gr 3212 FPS 75 gr 3262 FPS 76 gr 3303 FPS I will be running these at 74 gr. 75 gr and 76 gr both showed extractor mark. Then I tried RL33 with the 147 ELD-M 147 gr ELD-M Win case Fed 215M primer Loaded 2.750" BTO for .010" off lands This brass was once fired in previous workup, powder charges were reversed to attempt to even out pressure exposure on the brass. 72 gr 3101 FPS 73 gr 3173 FPS 74 gr 3214 FPS 75 gr 3244 FPS 76 gr 3284FPS Again, ill be running these at 74 gr. My 264 is going off to the gunsmith for a muzzle brake on Monday . [/QUOTE]
