That's all very interesting, but so far hasn't matched my admittedly limited experience.
Have tried the 150 ABLR in two .270's, a Ruger No. 1B and a BACO Model 70 Featherweight. They shot great from the No. 1 when seated close to the lands, but the Model 70's magazine length prevents them from being seated close. So far haven't had any luck with several different powders in the M70--which shoots both 150 Hornady Interlocks and Partitions very well, using powders from H4831 to Reloder 26.
