I've got several bigger/badder rifles than the 30-06 (which is the first rifle I ever bought) and I noticed that I wasn't taking it out much so I thought I'd load it down to the 150 grainers for something different - but I still wanted to take on elk if the need arose so I went with the 150 TTSX. I also had a keg of RL-17 sitting around and gave that a try. Turns out this combo really works.
The recipe:
58.0 grains RL-17, 150 grain Barnes TTSX, Fed 210 primer, COAL is 3.328" which is 0.063" off. This gives 3,030 fps out of a semi custom Sako Finnbear with a 26 inch, 1 in 10 twist #4 Kreiger (heavy sporter), glass/pilar bedded in the original stock but with Limbsaver recoil pad, the barrel floats.
Anyway at 200 yards it grouped 0.812" and 0.656" the last two times to the range. The thing that really got my attention though was the ES which was 5 fps for the first group and 2 fps for the second! If only my long range rigs could do that. I have no other rifle even close to this ES.
