I looked at both the h-bar and the standard barrel, and weight came down to being the only difference I could find. I think if you are going to get a competion barrel, go with an h-bar. I like the fact that I can use the same forend with all my standard rifle calibers. I would give the edge on knockdown to the 7-08. I too hunt from a ground blind, and you don't always get a good broadside shot. I just took 2 deer last week at 238 yds with the 7-08. Neither went more that 5 feet. the landowner whose property I hunt on won a tikka in 25-06 from the local game and fish assc., And he told me he prefers to take only broadside shots with it. I guess if loaded with a accubond or similar bullet, you would be ok. as for accuracy, I lazered off 300yds down a fenceline, set up a target, and from a good rest on a calm day, kept 3 rds under an inch, just at the bottom of the bull. I just love the 7-08!
