Care to share any of your load data on the PP2000MR? It is one on my list and I have a decent supply of it.
The brass... PPU 300Winmag reformed compares within 15-20fps with otherwise same/same loads on same day to my lots of Norma factory brass from both loaded ammo & bulk brass. My fired Norma brass holds 92.4gr H20 full to the top. Haven't measured the PPU.
All speeds instrumental. Oehler 35 center screen @ 10ft., so add what... 15-20fps for MV? Temps were between 50-70*F
With PPU 300WinMag reformed, Fed 215s. I got some 200FTX in a deal so used them to burn up for initial 2 shot groups for speed/pressure testing. OAL was 3.250". I forget the exact rationalization used for the start charge, but it turned out to be way low with my rifle & components. Speeds were very erratic with lower charges. Some ES were as low as 2fps while some were as high as 129fps. Dont remember if I did the muzzle up thing to move powder closer to primer. This settled down above c.72gr. The 1/2 gr. increments were omitted for brevity.
66gr.=2682fps

80=momentary lapse of something?
81=3098
82=3136
83=3154
84=3151
85=3174
85.5=3184- limit of powder compression. Still no pressure warnings.
Reshot the upper charges for speed & groups with Hornady 200 Sp.Pt. @3.300"
79=2966
79.5=3019
80=3036
80.5=3038
81=3070
to 85 not chronographed for some reason. Around 84 seems to be the happy spot for group size.
Same PPU brass & Fed 215s with Sierra 225s@ 3.410"
82=3036
83=3071
84=3103-good groups again at 84gr.
84.5=3109
85=3135- slight ejector mark on 1 case, called it quits here.
Started a series with 225 Accubonds @3.512"
82=3106-good speed poor group.
83=3147-poor group-ejector mark & clickers (2ndary extraction)
Pulled the rest apart
Same PPU brass, Fed 215s, & Speer 250 Sptz. @ 3.485".
79=2870-4 shot groups c.3/4 to 1" @100yds.
80=2888- ditto
81=2914- ditto
82=2947-groups opened above this with slightly more "feel" in bolt lift- no ejector mark
83=2976-still no marks, but definite bolt lift
