I found it kind of funny. I sighted in my PH after mounting anew scope. Iused the 240 gr mag express bulletsand the supplied sabot pushed by 90gr BH209. Very tight fitting but very accurate at 50 yds. (1 ragged hole).Moved to 100 and tried 250 gr Shockwavesbehing 100 and 110gr BH. I also used the supplied sabots but these loaded a bit easier. Again, very accurate but I only took 3 shots using the 110gr load (about 1.5" group). Then I loaded the Parker 275gr BE using 110gr BH again. Same target. These 2 bullets got lost in the Shockwave group. Also, ease of loading was about equal to the Shockwaves.

So....listen to Lee.Those loads should do you good. But I haven't shot any inaccurate loads in my PH. I haven't used any powder other than BH 209 in it either.
