That sounds like an amazing hog rifle! Did you have to significantly modify the bolt face to extract the pistol cartridge?
It was not easy, because the breach has to have an extractor slot so so the extractor can engage the case rim and it had/needed to be converted to a single shot, and that is why I would recommend a flat face bolt or a break open action like the T C Encore.
Where I hunt the chances of a follow up shots are rare and not needed because of the brush. If we want to thin the sounder we have a method that we use to line them up and hit then with a 300 RUM and 162 grain black tip penetrators at 600ft/sec more than in the 30/06'(Armor piercing) and normally 4 or 5 or possible with one shot.
