Red Leg:
I could not disagree with you more, respectfully, of course.
A .500 bpe or .577 bpe make excellent DG rifles, with the exception of elephant and hippo and rhino. Buffalo, both cape and water, leopard, lion, grizzly, along with moose, elk, bison, etc., are all game for the larger bpe doubles. Myself and friends have taken ours to Africa and there is no problem with them. I agree some old rifles have been messed with but it is easy to spot: calibers and proof marks, barrel ring/chime, etc., are easy and simple methods to check for quality. Most sellers will honestly answer questions but some will wait to be asked rather than offer information. Dealers will price high--that's why they are dealers. A book like my Primer will answer all questions for those new to double rifles.
While there is no doubt doubles are limited to range, I don't think they should be counted out of the picture. I've hunted exclusively with doubles for the past 10+ years. Leopard, lion, croc, and numerous buffalo, bison, and a few hippo and lots of plains game. I used my .600 fro a PG rifle my last trip to SA and Zim. No, I can't make 400 yard shots but my goals are to hunt not to assassinate an long ranges. Moose, grizzly and caribou have been taken in Alaska. An experience shot will use his doubles, bpe or nitro, to 200 yards with lithe problem.
Any who ask, I will evaluate doubles for them if they see a used one that catches their fancy. If a quality rifle is off face a bit, it can be repaired at little cost. The only thing that can't be repaired is a worn or pitted bore. Most lower priced new production rifles are POS, in my opinion. Sabatti's problems were not just with muzzle grinding to try to regulate, the wood to metal fit was poor, the engraving was down by laser or acid etching, the steel was low carbon and in damp weather the action would begin to rust, balance was poor, sights were bulky, regulation and accuracy was ok in some and poor in many others, and the quality of construction was also poor--ribs and sights that come loose, etc. Yet many bought them at 5$K as they wanted a double at a cheap price.
Of course, I'm a bit biased toward vintage doubles from the UK. I'e never regretted selling my Winchester express rifles to make the move toward the old doubles. I've encountered very few problems with the older firearms. Even the high priced doubles from the finest English makers still don't have the quality of older guns--engraving is more bold and not as fine, much of the work is machine done and not hand filed and worked. And, no matter the quality, the history of old rifles is something to behold. I will be posting some of my historical doubles a bi tlater on for all to enjoy. All are welcome to shoot them at our shoots here in AK. If you ever come to Alaska, Red Leg, please make a plan to stop by.
Cheers,
