Shot my first batch of rounds today with the 110gr AccuBonds and some H4350. Started at 42.0gr and went up to 43.5gr in 0.5gr increments. Loaded six rounds at each charge weight so I could shoot two 3-shot groups with each just in case I screwed the pooch on one of the shots in one of the groups. All were loaded with the ogive 0.030" off the lands.

First up was to get the rifle sighted in at 100 yards, so I used some factory Remington 100gr Core-Lokt loads for that.

42.0gr Group 1
AVG = 2813 fps
S.D. = 10.0
E.S. = 20.0
Group Size = 1-5/8" (pulled one wide right)

42.0gr Group 2
AVG = 2813.3 fps
S.D. = 11.1
E.S. = 25.0
Group Size = 7/8"

42.5gr Group 1
AVG = 2843.0 fps
S.D. = 19.8
E.S. = 47.0
Group Size = N/A (lost one)

42.5gr Group 2
AVG = 2843.7 fps
S.D. = 7.4
E.S. = 17.0
Group Size = 3" (pulled one high)

43.0gr Group 1
AVG = 2886.3 fps
S.D. = 11.7
E.S. = 28.0
Group Size = 11/16"

43.0gr Group 2
AVG = 2886.0 fps
S.D. = 2.9
E.S. = 7.0
Group Size = 2-7/8" (dropped one low)

43.5gr Group 1
AVG = 2922.7 fps
S.D. = 12.7
E.S. = 30.0
Group Size = 5/8"

43.5gr Group 2
AVG = 2939.7 fps
S.D. = 5.2
E.S. = 12.0
Group Size = 1-1/4" (pulled one right)

These cases had only been fire-formed with Bullseye/COW at this point so that may explain some of the wide variation between the ES and SD for the two groups with a given powder charge. No book data for the 110gr bullets that I could find (Sierra has 100gr and 115/117gr data), so I basically just split the difference for what they had listed for those two to come up with a probable charge range for the powder. No pressure signs at this point so I have loaded some at 44.0, 44.2 and 44.4gr to try out later today if the weather holds. Would really like to get 3050fps out of these, but with a 20" barrel that may be asking a bit much. Not getting a fireball out of the muzzle, so I might try a slightly slower powder to see where that gets me.
