I run the 143 and the 177 in my 7 STW. They both shoot tiny little groups. I purposely put a 1:8 twist 26" Carbon Six barrel on so I could shoot the 177. I've got a mild load just under 3100 fps with the 177 and a titch over 3500 for the 143. I'm limited to a max COAL of 3.700 for my Mag, so the 177 (which is very long) is seated deep in the case, otherwise I'm sure I could get a whole lot more out of it. I'm using RL26 for both bullets. I've only killed a south Texas cull buck on a friends ranch with it. Performance was spectacular, as always with Hammers. Buck dropped and vitals were destroyed. I know from a post awhile back, a member on here shot a cow elk around 800 yards with the 143 and his 7 RUM. She dropped and total vital devastation.
I'm now using the 143's in my 280 AI.
