I agree with Seafire. In cases up to the 30-06 case in volume, 4198 works great. I've had better luck with the IMR version. Cast bullets 170-230 gr perform well in the 30-06. A 311299 version at 215 grains in ww quenched gives me right at 2000fps and the smallest groups my Rem 700 produces at 100yds. Lighter bullets 150-110gr both cast and jacketed I use Unique or 2400 in 30-06.
The old 13 grains of Red Dot load would likely work well in the 270 under 130's, and I'm sure Unique or Blue Dot or 2400 could be used to good effect by a prudent and knowledgeable loader, but 4198 would provide a larger margin of error in finding safe starting charges, and of course Hodgdon has Trail Boss and the reduced data with H4895. AA5744 is pushed as a good reducing powder by the manufacturer, and my results have been great with it in several cases, but they want the Lord's good fortune for a lb of it.
Reduced load workup has really been my thing the last few years. I now cast the majority of bullets I shoot, and saving on powder has allowed me to shoot that much more.
