[QUOTE="JD338, post: 374832, member: 3719"] I quick tested the 100 gr E-Tip in my M700 Classic 257 Roberts and can share the following data with everyone. [img]http://i55.photobucket.com/albums/g147/JD338_photos/Oehler35.jpg[/img] IMR 4350 loaded to a Max charge with 41.5 grs, R-P case and Federal GM210M primers. Avg MV 2779 fps, ES 40, SD 20. Accuracy was 2.05". [img]http://i55.photobucket.com/albums/g147/JD338_photos/257Roberts100grE-Tipb.jpg[/img] RL 19 loaded to a Max charge with 46.0 grs gave an Avg MV 3053 fps, ES 38, SD 20. Accuracy was 1.772". The COL was 2.900" and I will have to work with this to improve accuracy. [img]http://i55.photobucket.com/albums/g147/JD338_photos/257Roberts100grE-Tipa.jpg[/img] I shot into water jugs at 100 yds, MV was 3042 fps and the bullet was recovered sticking out the back side of jug #5. [img]http://i55.photobucket.com/albums/g147/JD338_photos/257Roberts100grE-Tipc.jpg[/img] [img]http://i55.photobucket.com/albums/g147/JD338_photos/257Roberts100grE-Tipd.jpg[/img] [img]http://i55.photobucket.com/albums/g147/JD338_photos/257Roberts100grE-Tipe.jpg[/img] The recovered bullet weighed 98.7 grs and measured .584" diameter and the length is .635". I will update with accuracy improvements. JD338 [/QUOTE]
