Ramshot TAC or Accurate 2460

[Zale]

Just wondering if anyone is using either of these powders in the 6BR for 70gr bullets? I am going to be loading some 70gr Speer TNT's for shooting prairie dogs. I am looking for a powder that meters well and burns clean. Just wondering your experiences with these two ball type powders? Also any other recommendations you might have to offer. VV-135, while not a ball powder, my also be a viable option... Thoughts?

I have had no experience with the powders you describe and have had no luck with 70 gr. bullets in my 6mmBR but, I have had great luck with 68 gr. Berger HPFB and 35 gr. AA 2520. This load was given to me by a guy at Ramshot,they now own Accurate Arms powders)who was testing it. It shoots very well in my rifle.
I mainly shoot VV N135 in my 6mmBR but I am continually looking for other loadings because Vihta Vuori powders regularly are hard to come by.

I use faster powder in the 6BR for the lighter bullets, best loads with the 70gr SBK Moly were with XMR 2015 and an Accurate Arms powder called Data 73 which is faster than 2230, H-322 works great as well. Ball powders can give pressure spikes if heated in the summer sun. Rl-15 seems to work in everything from the 6BR to the 22-250 as does Varget. If I were going to load for the 6BR for Varmints with no weighing of every round I'd use XMR 2015 as it meters as well as a ball powder because the granules are so small. Interestingly, the most accurate loads were mild loads.
