Bonjour Caldix!!
Thanks for your kind words
Yes, I already have fully documented the history, after having asked H&H for its history.
Yes, the gun has 3 sights, 50-100 and 150 yard (veeeery optimistic?) I was not aware that magnum guns had 3 sights, and non magnum had 2. I dont have the gun with me to check the action, but I can post the records I have.
Although I fully understand your thoughts about the classic Brenneke slugs with fins, I still have to consider the sabot/jacket ones, because in that case, the slug will never get in touch with the barrel or rifling, getting the plastic jacket all the deformation at the barrel and rifling. In that case, that the slug has or not fins, should not be an issue. Brenneke is just a company, and they have many models
Precisely, people with modern Paradox style guns, with interchangeable rifling chokes, refer sabot/jacket ones. Some reading I found on a company that manufactures modern chokes with rifling :
https://store.geminichokes.com/en/blog/paradox-or-spreader-n9 They clearly recommend slug with plastic jacket/sabot
I have found 2 other alternative with plastic sabot or jacket
You might think, why don’t he just reloads (as you suggested)??. I have never reloaded (no experience what so ever), and MOST important, in Spain, reloading is very restricted, you need license that is very difficult to obtain to reload and to buy/store the elements, etc... So for me, reloading is not an option.
I send you some quick images I have at hand
Brenneke slugs, however tempting, are probably not a good idea, the bullet having its own 'rifling', and most certainly not recommended by H&H as in my case.
As written earlier I suggest you should carefully measure / having measured the bore, and order a bullet mould from CastBulletEngineering or other on these specs or 0,xxxx mm (see previous contribution) under.
