Would think that RL15 is not well matched to a 130 gr bullet in the 270. Calif Hunter provides a pretty good list. I am having very good luck with the short cut version of H4831, top notch velocity & great accuracy.
The Speer bullets will do just fine, tho' the TSX is an impressively accurate bullet in both of my 270's.

Imagine your grave on a windy winter night. You've been dead for 70 years.
It's been 50 since a visitor last paused at your tombstone.....
Now explain why you're in a pissy mood today.
