First..new here and I have the deepest regards and respect for any of you who have accomplished and polished this SKILL. I truly admire what you can do and with the highest sense of responsibility. My question is simple what is the biggest advantage to using 30mm over 1" tube. I know the 30 will probably gather a bit more light and may be stronger..but beyond that, then what? I have read other posts on other sites (negative comments) and frankly it does not surprise me. I have been a taxidermist for over 30 years and it still amazes me that a lot of hunters stil cannot cape their trophies and not able to recognize good work or tell the difference (think the same thing applies to LRH vs those that can't or won't). I don't consider myself a dyed in the wool LRH, yet, but have taken a couple of deer in Montana that were farther than the average hunter I think. I had a good ole .264 and practiced with it constantly at 600 yards (was as long as I could find), with lupy 3.5X10. I didn't hunt LR specifically, but if the opportunity arose and the animal was one that I wanted and I could not get closer, then I was CONFIDENT to do it. The longest was a good mulie that now hangs on my wall. And I'm danged proud of it. Tasted good too! Took that buck 18 years ago. Sorry to camo the question in all my rehetoric but I just had to say something about it.
