[QUOTE="highdrum, post: 2126507, member: 13732"] [USER=21446]@CA48[/USER] your data and revaluation is very thorough, I greatly appreciate all this information. I had hoped to run a node over 3200 in the 26" sst as my 25creed shoots very well @ 3040 from a 26" carbon rock creek barrel. As far as your 3220 - 3170 speed shift, I have never observed that much drop with H1000 from temps, from 30 to 100° was maybe 20 fps, that appears odd to me, that's why everyone loves H1000 is the extreme temp stability, at least that's why I use it. Barrel is getting spun this week will have it in hand next week and I'll get things popping and see where it falls in it. Where have you found the 131 to like being jumped from in the sst chamber? 5k, 18k, and 32k are where I usually try first. The creed shoots very small 18k off. Interesting in your findings of getting crunch with 63.5gr N570. I recently loaded some 156s - 30k in my adg prc brass, chamber has 240k freebore. I used a 16" drop tube and was getting crunch and compression over 61gr until I started using vibration to settle powder prior to seating. Was still getting the slightest crunch after that. This shows that the sst case is actually directly between the prc and saum capacity was. I also shoot a 6.5 max, I know I can get over 68gr N570 72gr Rl33 in that thing. [/QUOTE]
