150grn 6.5 sierra

[Stonefly]

Any of you 6.5 guys teied the new sierra 150. If so have you tried it in a 1:8 twist? Im thinking of trying it but am thinking it might be selfdeating with sierra recomending 1:7.5 twist

I haven't used them in anything I have. But a guy I know couldn't get them to group in his 1-8 twist 6.5 creedmor.
I have used their 160s in my .260 years ago and had the same problem.
A 1-7 should work for those.
I honestly think any bullet over 145gr is just too heavy in a Creed or the .260.
The 129 are my favorite.
