Jamison 358 Brass

Great quality and appearance. Very heavy brass. These weighed 30 grains more than Win 358 Winchester brass. Could not run the same loads as capacity very reduced. Will have to conduct completely new load work up for this brass as pressure signs showed immediately with just moderate loads. So good quality, but not standard brass

No complaints about the brass.
But I do have a complaint about the cost of shipping. I live in Alaska, ordered 2 bags (40 count) of 358 Win, and 7-08 Rem bag (40 count), and S&H cost me $18.00!! Would be nice to at least get a break in cost for Alaskan residents! Thanks!

358 win

Bought some 358 Winchester brass made by Jamison for my Savage 99.
20 count bags brass was nice, no dents, bent case mouths ect, tad greasy, easily cleaned/ wiped off with rag
Cleaned up inside of flash hole with debur tool, very minimum brass shavings, less than other brands.
Primers set with usual amount of force, set nice and snug
Brass chambered, fired, extracted no problem
Would give 5 stars, but need to see how it behaves after resizing/reloading ie, stretching, No cracking, primer pockets ect
So far I would recommend it!
Thanks Jamison/Grafs
