    Updating the loading bench, part 1: powder measures

    I have the RCBS electronic dispenser... she works great, not real fast but very accurate. When I was snooping around for a powder measure a year ago, I called the fellas at Sinclair International and they recommended the Redding BR3 or the Harrell custom 90. I trust those guys as they have never...

    7 mag load data

    OK, thanks fellas for the information. I will try some RL-22, I did try RL-17, there was no velocity at all with it, I think I need a longer barrel with some of these slower powders.

    7 mag load data

    I tried .040 - .005 off the lands in 5 thousandths increments. Also worked the powder charge up and down in 2 gr intervals. The 65.0 gr powder charge was the better of the lot, right at .020 off the lands. There is no pressure signs with this load, but the accuracy was not there. That is why I...

    7 mag load data

    Thanks, The rifle is a Remington 700 action with a 22" Douglas barrel. Twist rate was determined by a tight patch, a cleaning rod, sharpie, and tape-measure. After taking the rifle out and shooting some heavier bullets I decided to check as the groups were poor with the 175's and a lot better...

    7 mag load data

    I am needing load data for a slow twist 7 mm Remington Mag. with 1-11.5 twist and a 22" barrel. I did OK with 65.0 gr. of IMR 4350 behind a 140 Gr BT. Does anyone have some magic software that could tell me a good starting point with Varget or a powder with a similar bur rate? Thanks
