My results with Lever and Barnes 112 MB. At 29.4 brass was showing ejector marks but good accuracy.
I cut the powder charge down to 29.0 and had good accuracy and ejector marks were mostly gone so I loaded 10 with cci 450 primer and 10 with Remington 7 1/2 primers, at 2.363 o.a.l. (-20 thou from lands)
The cci 450's did well but the 7 1/2s first round showed near primer pierce and the second one did primer pierce.
After adding the 112 MB stats to GRT it shows danger level starts at 27.6 grains and I think that will be close to MAX for me, possibly 28.0
My tests were with Hornady 6.5 Grendel converted brass and Starline 6 arc brass. This was using a factory Savage Ridge line bolt action.
