Beautiful morning to shoot. Temp. at 57*F, very light winds. All shots at 100yds, using a duplex load of 10 grains N110 with 57 grains H4198, Federal 209A primers, Full Formed sized. All shots out of my Rem 700ML Smokeless conversion with a heavy contour barrel, this load combo has some recoil. This load is safe in my rifle, it may not be in yours.
Jeff Shiery at Bear Creek Ballistics is great to deal with. He said he could turn my bullets to any size I wanted, I went with .452 and .453. The listed spec on BCB's website shows .4513, 280 grains, with a B.C. of .325.
The .452 on the left weigh 286 grains and the .453 on the right weigh 287.5 grains.
First up, .452 with veggie wads, left target, 1st shot on a swabbed, cold bore is the highest shot. Group measures 1.82", loading pressure was a bit loose.
The target on the right (or next target depending on your device) is the first time I shot the new machined bullet, that was back in March, it was with the same load combo, except for knurling, and gave the same results.
.452 with wool wads, group measures 1.39", better.
Next up, .453 with veggie wads, these loaded with more force. group measures .91", better yet
.453 with wool wads, group measures 1.01". On my next range test, I will use the same load for the .453 and see If I can duplicate the results. With the .452, I will size them tighter and also try a knurled group. The old style BCB's routinely gave me 3/4" groups, the new style are starting to show some promise.
