Great report, Steve. Those CEBs are really "cutting edge", too bad they're so fugly! I took particular note of the Interlocks and it looks like the 270's "interlock" sits a lot higher, hence the greater retention. I used A Frames (300s) in my 375 and H&H on buffalo, but I'm a TTSX user now and that's what I use exclusively in almost every caliber.
A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
