My .501 / 250 Thors came so I headed back to the range. They shot exceptionally well (3 shots/1" at 100 yards) but not until I upped the charge to 120 grains of BH209. The groups definitely open up with a hot barrel. The first group is with a hot barrel, the second group started with a hot barrel & then I let it cool for 10 minutes between each of the next 3 shots. So shot one is high & the next three are very tight Average velocity was 2084fps.
The only issue that I had was 2 shots that went off "soft" & only registered around 1100fps. Unfortunately, I found no acceptable reason for this & I can't take a chance on it happening during a hunt so the remainder of my 50 pack will go on the shelf for now. I did switch out the box of CCI Mag primers for another from the same lot & never had another issue.
The HOT barrel group.
The COLD barrel group (shots 2,3, & 4)
Then I decided to try the Bloodline .458/220's again....with 120gr BH209, 2 next to each other & a "pull" on the third one. The fourth was just an adjustment for 100 yard height. These do shoot the tightest groups & since I don't personally know anyone with first hand terminal performance experience, it may just be another reason to give them a try. Last week I shot a 7/8" group, this week was 1 1/8"
Average velocity 2197fps.
