Re: 7mm RUM w/ factory tube and the 175 SMK?
A range report for you guys;
I loaded the 175 SMK with 3 different powders- Retumbo, RL25 and Thought I would try some RL22 as well. Trying to find load data for the 7 RUM was a little difficult, but managed to get a few starting loads with the above Powders. As a side-note I talked to Dave Brown @ Sierra and he said that Sierra was not planning to publish any data for the 7RUM, but he did give me some starting data. First working up with RL 25 I got mediocre accuracy with my starting load (the best accuracy with this ladder) but the velocity did not get over 2800 fps. With the Retumbo I got pressure signs right out of the hop @ 2850 fps. and with the RL22 I got about the same in the accuracy department as the RL25 and was getting pressure signs once I hit 2950 fps. I originally bought this gun for the action (I am a lefty and hard to find leftys in canada) But decided to see if this gun would shoot. Long story short I burn 25 grains more powder for what a 7mm Rem MAg will do. All of the negative I have heard and read about this caliber I experienced. Oh well I have a new barrel on order in .284 and probably going with the 7 mag.
