I'd have gone with Varget but am running low. RL15 looks to work well as an alternate.
H-4895 is not slouch either with the Skinners.....
Plus you can usually find H4895.
When Varget was unattainable there were guys on the Hide who switched to H4895 & 155's and they very pleased with velocity and long range performance.
Before Varget even existed, like many guys I used H4895 for my High Power 308 match loads
