I've been using a 9.3x62 for driven boar, but it's a little heavy on recoil shooting boar from a high seat, so decided to get something a little different, and chose the 7x64, which shoots a good range of bullet weights.
First off, I would check the availability of ammunition in your area. I always intended to reload for it, but needed some ammunition for a trip to Hungary, and hadn't had the time to reload. Because I intended to reload, it never dawned on me to check what factory ammunition was available local to me. Not a lot. Don't forget that the trade have major issues with shipping firearms, & ammunition at the moment, and at best, it's very expensive. I was quoted £60.00 for carriage, and the local dealer wanted £25.00 to accept it.
I'd picked up a box of Winchester 162g to test, when I collected the rifle, but the rifle didn't like it, not even good enough for boar ! Then fortunately, a local dealer found a few boxes of RWS 173g soft point, he'd had in stock for a number of years, and that worked very well, and will cover me until I sort a load.
So just check first.
That aside, I love it. Mine is on a Merkel Helix, and it came with a relatively short barrel. The RWS was quite slow across the crono, 2480fps, and I was a little concerned how it would perform on a boar. Turns out, no issue, certainly out to circa 150yds, where it passed through, doing what it needed to.
I'm very pleased, but I will still stick with 9.3 for driven.
