Sav 99, Speer #2053, & BL-C(2) or H100V?

I shot the incremental/evaluation loads a couple of days ago and thought I would post the target.
The first shot of the first load hit high, so I adjusted the Weaver K4 down and fired the second and third shots. The 43.5-grain load has promise, and the 45.0-grain load has no promise at 200 yards. The sweet spot would be somewhere between the two. I do think that this 180-grain bullet has little potential because of the exposed base in the case which is dictated by magazine restrictions with the 99.
Also, the 45.0-grain load did produce tough extraction. With QuickLoad corrected to the ambient range temperature, The actual vs. forecast velocity is together so will be the pressure. This load produced 54.0K PSI. If the group were interesting, I would investigate whether the chamber needed proper polishing, but I did hit it with JB Bore Paste, and it feels great to me. I think this load is just stretching the ability of the lever.
All this ended up being somewhat of a mute point as the mail brought me my Graf's order with the Speer #2035 165-grain HCSP bullets and MidwayUSA's order with the Weaver Classic V 2-7X32. The bullet will be able to be contained in the case neck now. Heck, I can reduce the COAL to 2.800 to give me further clearance in the magazine.
In that I was changing out the scope, I wanted to get real busy with the Weaver bases. With the Weaver product, the 99 uses the #19 up front and the #14 in the back. These fit many firearms so they are not perfect perhaps and that first high shot from a bore-sighted rifle suggested a slight mismatch which would flex the scope tube, throwing the shot. Sure enough not matched.
I'm not interested in a one-piece base in that I'm keeping the scope very low because of the carbine stock, and it's low comb Plus, the one-piece base always further restricts the receiver port. I got busy lapping with some 320 grit compound but soon realized this was going to be a big job so switched to 120 for some serious cutting. Worked my way back higher with the grit numbers as I finished the job. I'm not sure I've had to lap any rings this much and could have shimmed the front base higher but the scope will be 1.5" above the bore with the low rings, and I don't want it any higher. Anyway, that's done.
Going out to load this up and will shoot it this afternoon.
