I'm thinking about tryingthe Speer 300gr.GDHPin my Kodiak. Barne's Bullets work good in my muzzy but they are too much to spend on compare speers bullets. What I like to know is, they saythat these bullets are for 45cal handgun but are .451 diameter like the barnes bullets that I've been using. Can I used them in my muzzy with the harvester sabots. The Speer's bullets are .451 like the harvester sabots too. Has anybody use this combination or bullet? Any other sabots that will work with the Speer's bullet? Any advice for me before buying these bullets would be appreciated.... Thanks in advance.
