I don't think you need a Nesika action with a larger bedding surface for a barrel like that, or to bed ahead of the recoil lug even on the 700, you definitely don't need a bbl block.
I'd personally go 34-36" with that taper on a 700, no pad, which I don't care for or think helps accuracy. I'd go shorter if it was heavier bbl, or use a bbl block.
My Brother's 338/378 Rem 700 has a 32" barrel, his 500 Jeffery Ruger #1 has a 36", both have muzzle brakes in addition to that too. Mine at 30.5" 1.35 diameter straight tube shot fine without the block, even better now that it has the block and a recoil lug though.
Jay sold me a chunk of aluminum with a 1.350 hole already in it, I just machined it with Jay's as a model, which I liked best, just slightly different. I used 5/16-18 cap screws to clamp the bbl, and into the stock, I forget what Jay used now.
I was gone all afternoon yesterday or we could have hooked up at Jim Creek to shoot for a bit last night. We'll hook up some time. I'd like to go to the 600 yard match on Summer Solstice on Fort Richardson, this load I've been using should work fine, just working on wind skills lately while getting the drops nailed down in various conditions.
With a BC of .665 for the 210 JLK and pushing MV at 3175 fps, I'm pleased with the accuracy, wind drift and retained energy. I'd like to put some milk jugs up in front of my backstop and catch some bullets at various ranges to see how they compare, maybe I'll get the water tank in use I planned to build last year.
It's a pleasant rifle to shoot. Not quite what I'd use free recoil style, but pretty close the more I shoot it.
Here's some 3 shot groups I fired late last night at 500-600-700-800 yards to verify drops some more.
Ones I shot the other day in a little better conditions were pretty fair also, Wayne and Blaine have seen pix of them and the others I've shot with it in the new stock so far. Just three shot groups but they're pretty fair as far as the vertical spread goes.
This link might work for a larger view if you can't read the wrighting on it.
