proof barrel or hca ?

[Karl B]

I've shot a dozen or so HCA barrels and all have hammered.

As was already stated, they are Benchmark blanks.

+1 for BSF.
I know it wasn't one of the one in the poll, but I am on my, *scratches head* third, eh, fourth BSF barrel currently and I have nothing but positive things to say about their products and customer service. That is just on my personal rifles. I have put a couple on other rifle builds as well.
My 6.5 PRC is shooting 5 round groups in the mid .4's to low .6" area at ~75 rounds down the barrel. 147 ELD-M over H4831SC at 2780 FPS in 18" barrel

My 300 PRC barrel is shooting in the .3's for 5 shots. 225 ELD-M's over H4831SC at a forgotten velocity.

My 6.5-284 Norma is shooting ridiculous groups that I won't even admit to on a public forum to avoid the scorn. For comparison the first 5 shots out of it for break in went 0.22". 147 ELD-M's over either H4831SC or H4350. My dumb a$$ self traded this rifle off to a good buddy who is going to use it to beat me at a competition on my own range...

I am also very happy with the couple of Proof barrels I have dealt with but my sample size is too small to be a valid data point in comparison. I don't think that you have a bad option on your list.

Will be going with BSF for my build after this. Also helps they’re only hour away from home
