[QUOTE="brianwinzor, post: 35305, member: 1067"] Fifty Driver, I also agree with your comments about the comparison of the Sierra 117 SPBT and Nosler 115BT. The Sierra 117 grain bullet measures about 1.120 inches in length, and the Nosler 115 grain BT measures about 1.204 inches, so its bc of .453 is obviously going to be considerably more than that of the Sierra. Over the last 8 years I have been using the Nosler 100 grain BT at about 3,550 fps in my two 25/06AI's with terrific success on medium game (feral goats, pigs, roos, emus, deer, etc) in Australia. Due to my curiosity, I recently started testing the Nosler 115 BT, in my custom 25/06 AI (Sako L61R Action, Shilen 24 inch SS barrel), and found that the accuracy seems to be marginally better than what I achieved with the Nosler 100 BT. On my first day of testing, using a slightly compressed load of 63.0 grains of H1000, I achieved 3,256 fps, and consecutive groups measuring .420 inches at 100 yards, and then .800 inches and .480 inches (.192moa)at 250 yards when sighting in. Obviously I will fire further groups to verify this acuracy, and am looking forward to see how they perform on game in the field. Due to the .522 bc of the Berger 115, I also have been tempted to try it, but my limited experience with 70 grain VLD'S Bergers in my .224 Clark, and .22/250 AI, and 30 grain HP in my .17/222 mag imp, have had them coming apart when the velocity reaches a certain level, so I will use the Nosler 115 BT for while before trying them. I noted that you achieved 3,450 fps with the 100 grain bullet in your 25/06, and am curious about the barrel length and what load you where using, as you don't often see velocities exceeding 3,400 fps. I only got 3,377 fps(58.0 grains WW785) in rifle 1, and 3,342 fps (59.0 grains Viht165)in rifle 2 prior to both having their barrels set back and rechambered to the Ackley improved case. The benefits of standard v AI chamber is a hotly debated topic, but I have had many positive experiences. For the record the results in my 2 current rifles in the same barrel using the Nosler 100 grain BT are: 25/06 Rifle 1 -Sako L61R Sporter with Sako barrel Remington cases, capacity 65.5 grains 55.0 grains IMR 4831 - 3220 fps 56.0 grains IMR 4831 - 3269 fps 56.5 grains IMR 4831 - 3324 fps (Max) 25/06 Rifle 2 -Sako L61R Act.Shilen 24 inch barrel Winchester cases, capacity 67.6 grains 57.0 grains Viht 165 - 3205 fps 58.0 grains Viht 165 - 3265 fps 59.0 grains Viht 165 - 3342 fps (Max) 25/06 AI Rifle 1- Remington FF cases 71.2 grains 58.0 grains - IMR 4831 - 3432 fps 59.0 grains - IMR 4831 - 3494 fps 60.0 grains - IM4 4831 - 3565 fps (Max) 25/06 AI Rifle 2 - Winchester FF cases 71.1 grains 61.0 grains Viht 165 - 3472 fps 62.0 grains Viht 165 - 3547 fps 63.0 grains Viht 165 - 3591 fps (Max) Regards, Brian.
