Please take this in the spirit with which it is intended.
You need to find some DR shooters in your region and spend some time shooting with them. The questions in your last post suggest you are going to buy a heavy DG DR, without any experience. Take the time to learn about them. How to shoot them effectively on moving game. Stance, technique, follow through, aiming, reloading after the shot. All of that.
If all hell breaks loose, I want you to put 2 in the brain on reflex.
Take the time to do this right. Find a club. Join DRSS.
Nothing personal.
Thank you, truly. I appreciate it. But that's easier said than done. We simply don't have the pool of DR shooters up here that you do down there. Certainly no "clubs" of them. Just look at how many people post on here who are from Canada and how many are from the U.S. To give you an example, in all my years of going to various shooting ranges, I don't think I can ever recall seeing someone shooting a big bore double. I have fired a Heym .470 before, but it was a few years back, before I was looking at possibly purchasing something. And I'm an experienced hunter and shooter. I own 2 .375s, a .416 Rigby, and a .458 Lott, so "big guns" aren't new to me. And I've hunted Africa. So I'm not green, I just don't necessarily know what to look for in a big bore DR, and I was just curious as to whether what I'd taken note of with regard to these 2 rifles was typical.
Sometimes posting on a forum such as this can give someone trying to learn and do some research (which is what I'm doing at this stage) a great cross-section of information and opinions to consider. For instance, while examining these two rifles, I was able to implement some of what I'd read on here or a different similar forum as it pertains to checking a DR's "tightness."
Thanks again.
