300wm 215 berger recipes?

[Mumzergadol]

Anyone loading 300wm with 215 berger care to share OAL and jumps that they gave had luck with?

I'm going to roll my own based on the fgmm brass, 215s and h1000. My lands are a long jump for the load from federal, and it hammers, but curious what you are seeing

I did a seating depth test first on mine. But my magazine limited COAL so I started at max Mag length and went from there. I ended up with 0.050" jump. I use H1000 too. I'm not comfortable stating the amount of powder but can suggest starting at 73 gr and carefully go up.

Thx

.035 thru .045 jump seem to be the area to focus on with the 10 twists I worked up loads on.
Most liked the 76-77 grain area of H1000, but DONT START THERE, as mentioned above, work up to that area.

I've been toying around with this combo for a little over two months now. I can tell you that in my rifle, I worked up to 78 gr of H1000 seated to 3.60" OAL before I saw pressure signs. I hit 2 nodes on the work ups and my speeds are pretty good! I ended up at 74.5gr averaging 2925 fps. I felt that the lower velocity would be better on the rifle and the brass. I also started to seat deeper and my SD improved as well as groups. My rifle is a custom 700 built by GA Precision and has a 28" barrel. I'll be shooting this particular load out to 1 mile this coming October.

Thanks boys. Not looking to max out velocity. It's already so much hate on target, I'd like SD and accuracy

76.5 of H1000 is my best load, I shoot at .057 off lands because thats all I can get in my mag. I tested longer to see and my rifle likes them better with less jump, but single feeding them isn't something I want to do. I tested out to .11 off, but everything longer than .057 opened up more and more.

I’m running 78.5 gr of H1000 at 2910 from my
24” R700. .035 jump. Can’t remember the OAl off the top of my head but it’s long due to the factory chamber. I’ve not gone to a dbm for that reason. Mainly a hunting rifle.

I’m running 76.0gr H1000 and right about 0.85” jump because it’s as long as I can get in my Mag (my throat is getting kinda worn which is why it’s so long). I’m getting 2932fps Avg and about 13fps SD. I about need to start messing with it again to get the SD and group size down but it’s certainly throwing some hate downrange. Went second round hit from coldbore at 1-mile too. I will note I am right at having pressure depending on temperature. So watch where you start
