To be fair, and provide clarification that both DakotaDeer and JB may (or may not) be alluding to since this topic is specifically about the .366 cal A-Frame bullets....

It has been said/rumored numerous times over the years on various boards that the 250gr. and 300gr. A-Frame bullets are swagged down from the .375 cal Swift bullets.

There has been reports in the past of these bullets in the 9.3x (and a couple wildcats based off .366) not performing as typically expected. Thus, some folks are hesitant about utilizing said bullets in THIS particular caliber.

The 286gr. bullet is suppose to alleviate and address those previous concerns that some may have had. Initial reports I've heard and read have said that the 286gr. A-Frame is excellent.... and thus the reason for my initial post as since they were not listed on Swifts sight I was concerned that perhaps they had been discontinued...??

Glad to hear they are in production, and I look forward to trying them out for myself.
