It was raining all morning but I really had a need to do some shooting so I headed to the farm.
Tom had cleaned out one of the out buildings, the only things left under the canopy was a PU camper and boat... I was able to back under the canopy in the camper section - open the tailgate and the my canopy cover and work off my tailgate work bench and everything stayed dry.
I set the bench up in the next stall in front of the boat and walked the target out 35 paces - which I thought would be somewhare near 25 yards.... I do not pace for a living and it is a good thing - cause a was a bit farther than 25 yards. When I ranged it at the end of shooting with the range finder it was 37/38 yards.
The goal was to sight in a new Nikon Omega on a Knight DISC 50 and I also wanted to test a new Chrono that has not worked right the last two trips out.... I was reading a 3 digit number and that was really bothering me... I sent a email to Competition Electronics and the service tech very politely said - "you dummy... you have it set on meters/second" he didn't say "you dummy' but after him telling me what was wrong I know he was thinking that.... i didn't even know it could measure 'meters/second' Well anyway, he told me the key strokes to get it back to feet/second and now everything is good.
Anyway got the target out and the chrono setup and commenced to shooting. I was shooting the last of a box of 300 grain XTP's and I was going to shoot both BH and T7 - I decided to shoot 110 grain of both powders just for drill. Thought it would be a good place to start sighting the scope in.
The other experiment was I was going to use 7 different primers just to see if there were any big differences in velocities.
I did save the hotter primers to shoot the BH with but just for grins I decided to try a couple of Winchester T7 primers - just to see how they would do... no problems at all - instant ignition.
Nothing out of this world, but I was really surprised at the differences on velocities... I was sure that the BH loads would be a bit hooter than the T7 loads. I was using a HPH-24 sabot for all shots and this is a very snug sabot in this DISC Elite. I made a point of compressing the loads, both T7 and BH.
But, when you look at the velocities - I begin to wonder.... 110 grains must be the point just at turn over where 120 grains of BH will create a greater velocity with this 300 grain bullet than does 120 grains of T7. Looking back on one of my earlier spread sheets 120 BH does move the velocity faster than 120 T7.
Anyway it was a great rainy day activity... i advise it for everyone.
