An eight twist rate is marginal for the 115gn Sierra / Tubb DTAC match bullet and the two 115gn Berger VLDs. It's high enough to give you round holes, but the grouping may not be that great, and you lose BC, Berger's calculator reckoning an 8% loss of value.

On the above, you need a minimum rate not much above one in seven, but the American heavy 6mm bullet competiton shooting gurus say 7.5" is the optimal twist for these bullets.
