Swift makes a great bullet but the problem with the 300 gr 9.3 is that it is the .375 bullet bumped down in size and so the ogive is so that if you crimp on the canalure a lot of rifles will not handle it. I have three 9.3x62's and none will chamber them.
I have had great luck with the 286 Partitions and you can't go wrong with either bullet
You're right. But Swift finally came out with a 286gr. .366 cal A-Frame specifically for the 9.3.
No more swagged down .375 bullets!
A link to a discussion earlier this summer that may be of interest. Discussion concerning both bullets in question.
