I've had two Win 70's now that had to be shimmed under the rear base to sight in at just 100 yds. I had a Featherweight that needed 0.041" to hit at 100 yds and be optically centered. I just tried a Model 70 Classic in 375 H&H on Sunday that was a little over 2 foot low at 100 yds with a new...
NICE!!
Have you sighted it in yet? If so, did you have to move the reticle up much to hit your aiming point? I've had two Win 70's now that had to be shimmed under the rear base to sight in at just 100 yds. I had a Featherweight that needed 0.041" to hit at 100 yds and be optically centered. I...
That was the first load. I used Nosler data for their 150gr to start with this 140gr Barnes. I had a box of the old style "X" bullets I thought I'd use up first to see what worked best before using up the new TTSX 140gr I had stashed. Not sure I need to look too far for the right combo now. I...
Thanks!!
I'm very pleased with it. I tried some 168gr Berger VLD and could only get those just over 0.750"..It's wearing a Leupold 4.5-14 VX-3L 30mm, Bell and Carlson medalist stock that I glass bedded
I just finished this 280 AI on a Rem 700 +0.010" blue-printed action, Shilen 24" tube. 1st load I tried with some very old Barnes 140gr X boat tails went 3 into 0.379" at 100 yds. I used 60.5gr H4831SC, Winchester LR primer and Nosler brass. I didn't have my chrono with me today.
Here's a link that should help. I wouldn't expect blistering speeds with that short of a bbl though.

Try one case with die backed off 1/8 turn and see if it chambers w/o any difficulty. If its in a bolt rifle, it should go right in. Then shoot a couple with the same load and see what happens with your primer problem. How far off of the lands are you with the bullets you're shooting?
When I do a partial resize with a full length size die, I raise the ram and screw the die down to just touch the shell holder then back it off roughly 1/8 of a turn. That will give you plenty of neck tension and you know you aren't into your shoulder.
That line could just be where the die is actually sizing to. Take a micrometer or calipers and measure there and compare with a factory load. Its just not that shiney look you get with brass stretching.
I went back and looked at those pics again and agree that they look like they have stretched some down at the web. Toss those like mentioned and go forward with the other brass.
Negative on the decap. You can keep the brass etc. Continued firing with your current settings will shorten brass life. You could pull the bullets and reduce the powder charge, load the bullets long enough to just touch the lands so the case can't jump. The case will then just expand to fill the...
I agree 100%, probably sized down too much creating excessive head space. If you were truely over pressuring those loads, your bolt wouldn't want to open so easily and extraction would be hard as well.
I do need to make a disclaimer on the group size. I had forgotten to bring my rest out to the range with me so I was only able to put a borrowed bag under the forearm. I couldn't get a good cheek weld with the rifle so close to the bench top and pretty much just tried to put the dot in the same...
Thanks. I was thinking about trying those and Accubonds. I have avoided using Scirocco basically because Swift was very (let me be nice here) nasty when I asked for some loading data a few years ago. I haven't bought any Swift bullets since. They told me to "buy the book" and wouldn't give me...
Ok, took it out for the 1st time today. 120gr Barnes TSX with 58.0gr RL232 went 0.446" at 100 yards(I can cover with a nickel). These were loaded 0.050" off the lands. I tried three with 66.0grs of Ramshot Magnum which had the same basic group size and POI as the RL22 rounds. I didn't have my...
