Other than making my wife think I lost my mind is it worth it?
So the back story is I have aquired a lot of .22 WMR ammunition and have a fairly accurate Savage 93 FV rifle. So I was sighting in my new scope for the rifle the other day and I had some 5 shot groups go under 1" and others over 2" at 100 with the same ammunition. I've always thought of this as a max 150 yard rifle on prairie dogs, if lucky I could stretch it to 200 yards. I felt I was shooting pretty consistent so I was wondering how I could make it more accurate.
So I pulled out two bricks of Federal Premium 30 grain TNT HP and my RCBS 1500 gr pocket scale and took over the kitchen table last night. I was surprised at the wide range of variation in cartridge weights with a low of 54.6 to a high of 56.1 grains. The largest average was between 55.4-55.6 grains. Here is how it broke down.
54.6-54.9 gr = 10
55-55.2 gr = 197
55.3 gr = 86
55.4 gr = 171
55.5 gr = 166
55.6 gr = 239
55.7 gr = 60
55.8-56.1 = 71
I know the proof might be in the targets to tell me if it's worth it or not. Anyway I have several more thousands of rounds to sort, that I'm not looking forward to if this shrinks my groups. I guess if it'll give me more consistent hits beyond 150 yards on pasture poodles I'll be happy.
