30 SM with the 245 EOL

started load development with my 30 SM and have fireformed all my adg brass. these 245 eol are going to be crazy easy to load develop for. picture shows my .3 grain increments. 100 yd target with each of the 10 loads attached. using n570.
ended with 82.7 grains @ 2973 and still no pressure signs including ejector marks. gonna go up a couple more but 2950 is looking really good. we will see

rockwallraider, Your notes say N575 is this a misprint or another new Vihtavuori powder that hasn't been announced yet? I now they have came out with N555 and N565. by the way looks like you have a winner

N570. Just in a hurry to get out door.

ran a couple more with no pressure, not even an ejector mark. crazy
83.3 2991
83.6 3002
83.9 3003

used same target and just kept printing bug holes. will try and load up
84.2
84.5
84.8
and 85.1 tomorrow

Keep the data rolling!
He has a 26" barrel folks

Id be very interested to see how primer pockets hold up at those loads. Even though youre not seeing pressure they may not last.

Very impressive though!

Hi Shawn. I have 7 firings on similar loads with various powders and bullet weights and still holding strong so I too am interested in how this comes out.
He has to be very close to X marks.
I was testing for max loads and he is now just passing where I stopped.

Wow. 3000fps with the 245gr. High dosage of medicine for some critters

I know 3000 is doable with the PRC.

300 prc
originally, It was the 30/375 S. I. when I designed it off of the 375 Ruger about 10 years ago.

Thanks. Sound like a real winner.
