7/300 loads

[rogue savage]

I'm putting some load notes together and figured others might like to see the info collected in one easy to get to spot. These are not my loads and I haven't tried them just copy and pasted the info, so use your noggin when loading. If I have misquoted your info let me know. Feel free to add to this list.

Thanks to all the helpful contributions to the Anyone own a 7mm 300 win mag thread.

My loads are for a 7-300 win mag AI. My case holds a few more grains.
The 83gr reutmbo and 3500fps with the 162 amax was a fire form round with an older lot of retumbo,
With a new lot of retumbo and fire formed brass 82 gr was max....primer pockets getting loose after 3 more loads. With 81.8 it was only taking 7mpa to get to 600yds with a 100yd zero. Still very fast.
But on some rounds getting a little sticky bolt lift.

I'm going to get back on the chrono and try less. I will to start at 80 gr. since this lot seems hotter than the last. I'd like to get 3400fps.
That was a very stable node when I first tested.

I shoot 73grs of H-1000 in RWS brass in both of my guns. In the 27"Schneider it runs 3190fps and the 28" barrel runs 3230fps. Both shoot 3/8" or less. The other load you have listed is a load for a 28" Bartlein barreled gun I built for a guy named Jorey who posts on here. I believe his handle is remington 25-06.

I shoot 73 hrs of h-1000 in rws brass topped with a 180vld hunting bullet with f215 primer and get right at 3100 fps. Not the fastest but shoots 3/8 at 200 yards. 28 in lilja barrel. Love this load!
