EH,

For double rifles, especially the big bores, you want them to fit like shotguns with almost no need to sight when you are out of time with dangerous game.

I have one bolt in .375 H&H and the length of pull is only 14-1/4" rather than the usual 14-3/4" or so. Key again is being able to use the iron sights quickly and comfortably in a hurried situation. I find that with the scope on I can always adjust to the extra height as there's more time generally.

Regards, Tim
