Sounds like a nice build, you will like the bolt action versatility for supers or subs. I had a hard core 7.62x39 guy stomp pretty hard on my mention of 300 BLK. Once he was informed about shooting bullets from 90 -245 gr at whatever velocity I wanted, he backed up a bit in attitude. I explained I could do it all in my RARR and in any order. I have no ill feelings about his choice in platform, mine however seems seems a better fit for me and the grand kids
With this project I thought long and hard about which chambering to go with, the 7.62x39 was definitely a contender, as were 6x45, 6.5 Grendel, 338 Whisper and a few others. As always it came down to form following function. Proper bullet selection and super loads should support hunting medium game out to reasonable ranges, varmint work and target shooting. I also wanted the ability to run subs accurately and hopefully this barrel allows that.
For optics I went with a Vortex PST 2.5-10 with their EBR-1 mil/mil reticle. 10x will be more than enough for my ranges, I like the graduated reticle for ranging and use with different loads and it is illuminated which with the lower powers can be handy dispatching pests.
The stock was a tough choice. I've used Manners, B&C, Stockade and a few others, even went with a chassis system on 308 for a while. The big difference with this rifle is that it is intended to be used 99% offhand or with an improvised rest at best. That being the case the factory stock kind of fits as a light, quick handling option. I'll at least give it a whirl, with some pillar bedding and maybe a little stiffening up we'll see. I also have used Hogue's overmolded with the full al frame and it may be an option- open to suggestions.
At this point have everything but the barrel, which *should* arrive any day.
