Springfield XD 357 with standard 4"
barrel
Starline brass
Winchester primers
West Coast plated 147 grain hollow point
bullets
Note: The Rainier 147 grain bullet has a similar cone nose profile as a
Hornady Jacketed hollow point, although the Rainier bullet has a slightly wider hollow point. It also has a slightly
shorter bullet length than many of the other 147 grain bullets I’ve looked at.
I like the Rainier 147 bullet since you can buy it in bulk for aprox. $48 per 1000 at gun shows or from
Midway for $52. Not bad at all for a decent plated hollow point bullet.
If anyone has any good 147 grain bullets that work well in the 357 Sig format, please email me (see my address below).

fluctuates significantly, which affects the overall cartridge length
(OAL).
