Incidentally though, i believe the sako/tikka,s perform well with factory 100 grainers, especially sako,s own brand.They could be using a very slow powder, which is apparently one of the tricks to get better accuracy from a 100 grain bullet.

 

Have you pulled the bullet, measured the length, and compared to other 100gr pills? appropriate twist to stabilise depends on length of bullet primarily, not weight..Just so happens the heavier bullets are longer, so generalisations make it easier to compare off the cuff..
