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...
Hey, what kind of recipes have been cooked up for the new 250 GR AB in an 338 RUM?
I have a dandy 700 Remington with a 4.5-14 CDS Leupold. I have several loads worked up for it in 225 but am looking to shoot the new 250, anyone out there futzing with this???
Would like to get it dialed in and...
Thanks for all posts
I have tried several powders and the best load for this barrel I have found is 60.5 gr.s of RL-17 behind a 160 gr. Nosler AB
MV average is 3022 FPS
extreme spread is 8
Standard deviation is 4
0.488" groups @ 100yards
These are seated .02 off the lands.
I shot 2 three shot...
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.
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...
I am getting 3216 avg. with 140 BT behind 65.0 gr. IMR 4350, but accuracy isn't there. This is my Dad,s gun he just sent down to me to "tune up" for elk.
Any ideas?
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...
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
