Started out the morning sighting in an older Burris Short Mag 4.5 x 14 scope so I could take it to Kentucky as a spare (mounts and all). While messing with it and the 225 FTX I managed send my short little bore guide down range somewhere?? It is not a problem since the bullet can pass thru it……..just that the pressure that follows launches it. I have done this several times in the past 8 years playing with these ML’ers Found a couple out in the grass but not this one. I need to make them wider so they are more visible. I was only aware of it when a shot went about 6” high and to the right. Thought it was the scope…………took it off and put on the Leupold MK 4. Went to load and…………………….No bore guide………….since that was the cause of the flyer, I re-installed it and put two shots touching. That scope and rings will go to Kentucky!
So, again, re-installed the 16X MK IV and fired the first shot. Then three more. The last three touched for a .543” group. I discounted the first shot as getting the scope settled in.
Make a windage adjustment and moved the same load out to 300 yards.
Using the first mil dot which would give me 6 ½” of elevation at 100 yards it printed4” low at 300. Why shot #4 moved out to the right…………???Could not see any wind showing in the Indian grass? In any event, shots 1, 2 and 3 went .992” with shot 4 opening it up to 4.2” and shot #5 coming back into the group for a 2.1” Best 4 out of 5 group. ½” of vertical for those four shots ….all five still only 2” of vertical.
Mind you, not one my powder charges are weighted on a scale. These are all thrown with powder measures. The Clays with an old Lyman #55 and the main charge with a Harrell’s measure. I am not trying to preach NOT using a scale, just saying that a tenth or two either way has never made a difference for me in my muzzle loader. I scale to the kernel for my long range CF loads…………ONLY!
OK, the 275 Parker BE??? Maybe the load? Who knows? I got a good ES but a terrible group.
So now to the 290 Barnes TEZ . This time I put the first mil dot at 12:00 on the bull. Shots 2, 3 and 4 = 1.0”,,,,,,,,,,,,,,shots 1, 2 , 3 & 4 = 2.4” . So what happened to #5 to make it 5.7”? A very light left to right breeze had come up as I could see the dust from Herman’s shots drifting towards my target. Did not think it was strong enough to move it that far but it is what it is.
Lastly at 300 I shot the generic 250 Hornady FTX with the same load and hold. Note here an extremely low ES ( 11 fps for five shots). This time shot #1 spoiled the otherwise nice five shot group.
The last group of the day was back at 100 yards with the 200 gr. FTX. Not great by not all that bad.
Note: All bullets were knurled up to around .455 and full formed. Other than the 10 shots with the old scope, the rest of the groups were shot using the 8/58 Clays/H-4198 load.
