Well, I finally got the .300 out to the range again. For those of you who weren't in the old forum, here is a recap:
I have a 1947 vintage model 81 in .300 that was hitting about a foot to the right at 25 yards. I had spent months trying to find a tool that could get inside the shroud to loosen the set screw for the front sight that was listed in two different schematic drawings, so I could finally drift the sight and fix the problem. I finally found the old forum, and somebody told me that if there had been a set screw, it would have been visable from the outside. After a few minutes of banging my head on the desk, I went and ordered a front sight adjustment tool from Midway. It took a LOT of pressure and cranking on the screw. It finally went POP! and moved over, and I have been waiting for a chance to get to the range to test it out.
So, the range report. I was using my regular load of (iirc) 40 grains of IMR 4895 under a 150 gr flat-based spitzer. It gets between 2550-2630 fps depending on which gun I use. The windage was right on (after a bit of minor tinkering), and it was hitting about 3" high at 25 yards. (I didn't have time to drive out to the 100 yard range, and wanted to make sure that it was at least close to the POA before driving 45 minutes to get there). Standing and shooting without a sling, 4 of the 5 five shot groups were under an inch and a half. The flier on the third group was my fault, and only was about a half an inch higher. I probably could have done a bit better from the bench, but alas, somebody else was using the only sandbags, and I didn't remember mine. Such is life. I'll post more on this one and on the .35 when I head out to the real range in a couple of weeks.
