[QUOTE="J E Custom, post: 161612, member: 2736"] [b]7 Rum[/b] Dito on what kirby said. I had a custom 7 STW bilt when thier was no brass except 8mm rem mag looking for a really flat shooter. The rifle was bilt on a browning hi wall and had a 31'' barrel. After extensive testing this was the results. The highest velocity reached was 3817 with a 120gr bullet but accuracy fell off at around 3700ft/sec. With the 140 3538ft/sec was the best I could do but brass life was 2 to 3 rounds at best. Later I bough a Rem sendero in 7 STW an was only able to get 3468 ft/sec with a 140gr bullet. I now have a 7 RUM with a 26'' barrel and factory loads produce 3543 ft/sec with a 140gr bullet. These are real velocities using a ohler 35p chronograph at 75 o NOTE: All these loads were to hot in the summer (Texas avg 95 to 100 o ) So be happy with a usable 3500 ft/sec load with a fac 26'' barrel. you might be able get a little more with reloads and still be safe. I have no data on longer barrel 7RUMs. I hope this helps J E CUSTOM [/QUOTE]
