Finished the testing and BH209 load search.
Wow. 1st i got the 700ML 45 with bolt nose and savage plug out and tried. Easy peasy to get moa. Started with 50 by volume just got on paper. All loads were under HSB with light knurled 200X40 SST. With 75 and 85 by volume got just over moa. At 100 volume, 70 by weight, got consistent 1 moa or less depending on me. Slick loading for 2 shots then bore swab, then a 209, then load and shoot apply cool rod and wait 5 minutes and 2nd shot. The 75, 85 and 100 volume shots at 100 yd. Scope was 4X40 fixed power Silver Antler. Winchester 209 primers. That Remington upgraded is the ticket and will be on way to WY soon. I'm thinking a better scope and it'll shoot even better. Cleaning regimen between groups was Ed's red patch in out and turn over and repeat and then in out with 2 dry patch.
Then more work with the 50 bore Omega. Have not been doing well with heavier 45 bullets. The 40X50 sabots with 200X40 SSt was pretty good. So searched the cabinet and found some stuff that gave 1.5 moa consistently. Tried some .429 X 240 deep curls and they gave better than 2 moa. Then some .429 XTP and they were close to 1 moa. Best loading was the 85 grain for 240 grain deep curl and 100 grain for the 200 XTP. All were shot in smooth green sabots. Had to trim the sabots for the 200 XTP as they were so short.
As with the 45 the testing for 50 was at 100 YD. Ambient temp was 48 F. Cool rod used for 45 and 50. 5 min or more between shots. 5-8 mph wind direct from 6 down range. Black horn 209 powder. Winchester 209 primers for the Remington 45 and Federal 209 for the Omega 50.
Well, clean everything up tomorrow and pack the 45 up to go to WY.
Everyone have a safe turkey season this spring. W
