Speculating that this should, maybe fix the pressure spike problem, that happens with Retumbo and 180 ELDM & 195 Bergers?! I can run my bullets long, so where the bearing/boattail meet neck/shoulder junction, but my case fill is, nowhere near 100% with Retumbo.
Got out on the range today for a while, to give it go, so far so good! Testing some new components, that aren't from the unicorn fairy, while gathering data for a new 27" 1/8tw barrel.
110 Savage [receiver lengthened .250 for max length 7STW, way back when] 26" 1/9tw barrel
*Hornady 28 Nosler case (they required an additional anneal before use, bullets were very difficult to seat, hard brass!) Waiting for the Peterson 28 Nosler, that was ordered.
Starting light: 18 shot string .5 grain increments. Looking for pressure/velocity, not flat spots.
Magneto Speed Sporter on Wiser Precision mount. Shot from bench. Atmospherics: 74F, 25.08inHG, 42%RH, 7104DAlt. Humid for eastern Colorado plains today, bringing down the DAlt, which is usually in the 8000ft range.
Easy bolt lift and zero pressure signs, with this powder/load. Didn't find max today, but it's a very good start.
I've been working with Ramshot LRT and I'm liking it a lot. Compacts nicely in the case and meters like a dream! I've pushed a 300gr Scenar to 2933fps with 101.5gr. At that point I'm getting some sticky bolt lift so that was a one time deal. The sweet spot seems to be 96.5gr with about a 1gr wide node. Need to do some jump testing but it seems promising and moderately temp stable. I shot this ladder at 94 degrees and aside from some mild primer flow (I need to have my firing pin hole bushed) saw nothing scary...
