I shot a short range ladder at 100 yards with the 210 ALR, i think my accuracy window will be between 78.5-79.5 grains, based on the very little difference in vertical dispersion. I dont know what happened with the 78 grain charge. Next time out i will load 78.7, 79, and 79.3 grains and see where i am for accuracy with the ALR. I started getting some ejector marks on the 80.5 grain load and only had one more round left so i shot the 81 grain load and a good size ejector mark showed itself but i didnt loosen the primer pocket.

I would probably give the 230 targets a try before the 215s. With Broz's results from last season, they seem to be just a bit too soft for my liking. The results Broz and his son have had with the 230 OTM, and them exiting all the time but still expanding great, is a little closer to what i consider ideal for the purpose of this rifle, a 0-1000 yard elk hammer.

Biggest fail of 2014 so far... http://www.longrangehunting.com/foru...ea-ftf-128972/

My guess on W3P .308 230 Grain Bullet: G1 .740-.755

The 230's didn't group quite as well in mine, although they weren't bad. I have over a half box left that I could ship to you to try if you want......Rich
p.s. did the 230's expand at 1000 yards for Jeff?

I will see how these 210 ALR turn out first, if they dont work out, i will let you know on the 230s. I dont know if Jeff's son has shot anything with the 230s at 1k but he shot a mule deer buck at 893 yards with his 300 win mag at 2775 fps MV.

Oh, and i do have a chrono, but it hasnt been working lately, i will be getting a magneto speed soon.

Hey guys i did some reloding for the 30/375 S.I. today and thought i would snap this picture. The case on the bottom is seated .025" off the lands and the one on the top is .040" off. You can see the 210 ALR is a good fit to this cartridge.

Re: My Dad's 30/375 S.I. by Straight Shot Gunsmithing

I shot last saturday, with two groups with 78 grains of H1000, two groups with 79 grains, and one group with 78.5 grains. Groups werent very good, but i think i need to get the seating depth dialed in.


The first pic is 78 grains. I dont know why they are turning on me, sorry.
