Ringman,
Reread my initial post. If you are a real gunbuff? you may know velocity is not always the Holy Grail. If pure velocity is what you are looking for, you are looking at the wrong cartridge. The 30-06 cartridge is one of the best cartridges known. It is not the fastest or most accurate. If you look at both of my post, I said the advantage is the larger bullets, not the 150s. Don't take part of it and decide what you think I wrote. Tell me what you gain with 187fps. What if the most accurate load was 2750, would you go faster because it could or would you shoot the most accurate load?
Ringman, I have made a lot of wildcats and sell custom case forming dies. I have shot my 22-284 at 3800 with 89grn. JLK bullets. What a waste of a barrel. Somebody mentioned a Swift above. I had one and it was a great shooter, but I sold it after 25 rounds. I had a 17x22-250AI. Another big mistake. I guess it all depends on what you want a rifle for. I shoot BR and hunt.
I have been around the block.
