[QUOTE="lightflight, post: 779448, member: 45563"] bellow is some data I found online 65wsm - I had R19 which is why I started with that Powder. I also have IMR4350 but that looks to be faster burning. Powder is hard to come by right now. the start velocities below were with a 24" barrel. I was hoping to get a 150gr bullet up around 3150fps accurately. 270 WSM Start Load Approximate Start Velocity Max Load Fill Bullet-----Powder---------Start load-Velocity--Max Load--Ratio 150 Grain--H4831 SC-------57.5-------2728------64.0------96.7% 150 Grain--NORMA 204------56.0-------2856------59.0------90.1% 150 Grain--RE-19----------56.0-------2827------60.0------94.6% 150 Grain--AA 3100--------57.0-------2726------62.2------97.0% 150 Grain--H1000----------61.0-------2757------66.5------100.8% 150 Grain--IMR 7828 SSC---56.5-------2756------62.9------95.5% 150 Grain--Ramshot Magnum-61.0-------2722------67.9------98.9% 150 Grain--VIHT N160------54.5-------2658------60.8------95.0% 150 Grain--WW WXR---------57.5-------2796------62.4------94.8% 150 Grain--AA MAGPRO------59.5-------2752------66.0------97.2% 150 Grain--IMR 4350-------51.5-------2780------57.5------90.7% 150 Grain--RETUMBO--------63.0-------2707------70.0------104.4% [/QUOTE]
