[QUOTE="Doublezranch, post: 940128, member: 32664"] Went back to the range to finalize my 300 rum load. Brought the chronograph with to see how fast we can get the 230 Berger going. Results where staggering to me. My ladder was 103.3 to 104.5 grains. I was suspecting that my most accurate load would be at 103.6 with my top being somewhere around the 104 mark. My results showed my most accurate load was 103.3. Hole in a hole with my first 2 shots and then the pressure got to me and I pulled a bit on the third. I did run the ladder up to 104.3 where I had a major crater on the primer and hard bolt lift. The thing that spun me in a circle was that this load was very, very accurate. The three holes were touching. I found power nodes with 33 are not the drastic open groups in the middle of the nodes. There is only around .5 to .7 grains difference in nodes. Now, the fun part. I chronographed every load and again, super surprised. Results as follows: 103.3 - 3200 103.6 - 3210 103.9 - 3230 104.2 - 3250 104.5 - didn't shoot My conclusion is that this powder is going to be a game changer for so many large bore and fence caliber rifles (wsm and saum). It will also be a headache for Alliant because everyone that has tested it has a different starting and ending point. Load data will be generic at best. The fact that you can fill the case with powder and not blow yourself up is amazing to me. I have been shooting 7828 ssc forever in my ultra mags with wonderful results. But never once could I fill the cases and get uncharted velocities without some sort of pressure sign big or small. I sure hope that whitetail I saw at 1350 last year pokes his head out of the trees again this year. I want him to say hello to my little friend!! :D [/QUOTE]
