Shootall: if you get that 44 magnum M92, get onover to Veral Smith's website and read his recent posts or rsponses to AtLaws questions regarding what slugs to use in the 357 he has.
In my post to you I mentioned I prefer the 200 gn slug. In running this issue past Veral Smith, Veral told AtLaw that his preference for the 357 was a 180 gn slug of his LBT design and that the 200 gn slug was too heavy for the bore. When I found favor with the 200 gn slugs it was during the metallic silhouette days with pistols and revolers shooting to 200 yds and unless you cast and loaded Elmer Keiths 173 gn swc, there was nothing between the 158 gn cast and the 200 except his 168-173 gn cast swc.
Now, with geniuses like Veral Smith, LBT slugs like his 180 gn fn are the real performers in the 357 mag, more so than the 200 gn slugs and based on Veral's response to AtLaw I think I'm going shopping for some of Verals 180 gn fn slugs.
With that in mind, knowing that you are seriously looking at that 44 magnum M92, I would heartily suggest you contact Veral for his recommendation as to which of his bullets would best serve you from that carbine. Who knows, it may not be a 240-250, or even a 300 gn, it might be something in the 270-280 gn range. I would run it past Veral for his input, and I hope this helps.
