Here are my 35 Whelen plinking loads. All loads use a 158 gr jacketed pistol bullet and CCI-200 primers.
13.0 gr W-231 v= 1,527 fps 0.60" 5-shot grp @ 75 yds (Hornady XTP used) [best load I found]
14.0 gr Blue Dot v = 1,441 fps 1.05" 5-shot grp @ 50 yds (Speer JFP used)
15.0 gr Trail Boss v = 1,515 fps 1.35" 5-sht @ 50 yds (Speer JFP used
16.0 gr Trail Boss v = 1,560 fps no group data
From a 1:12 twist, 22" barrel. COAL = 2.825 - 2.835"
They will have different POI than full house loads. Can't remember if it's higher or lower. You should be on paper at 50 yds though.
One more thing - I used a .357 Mag seating stem screwed into the Whelen seating die (luckily both were RCBS and interchangable)
