Begara B14 handload recipes .308?

[Cal50]

I have a B14 I don't shoot an awful lot so loads development is very slow.

I've found Factory Federal Match 175grain to work well. And through my own development 175grn Sierra match king hpbt with 36grns of N140 and Federal primers to be the best (3/4" groups @ 100m).

I've ran out of bullets so need to order some more, is it worth giving the Sierra 168's and 177's a go with the same charge and go from there? Ideally I'd want to stick with N140 since I already have it but any recipe recommendations would be appreciated, especially if I can see trends with it.

Of course I'll be checking all recommendations against manufacturers published handloading data before loading.
