Well, Tuesday is our normal shooting day but the weather did not look all that great with a serious threat of rain. But, Wednesday was also not looking good weather wise and Thursday had other things going so we “bit the bullet” and took our chances. We knew it was “breezy” when we got there but it was not raining yet. Well, that breeze turned out to be more like wind in the 10 to 20 mps range with some gusts probably a bit more. We were hoping it was going to “lay down!” It did not! I was disappointed since Kyle had sent me a few 300 gr. AerroMax bullets to test and I did not want to waste those precious little pearls shooting 300 yards in the wind. So I decided to just play around with various weight SST’s and a up graded duplex consisting of 8 gr. of Clays under 66 gr. of H-4198. All the bullets I shot today used that load along with NO wads. The wind was coming from the range house to the targets quartering from 7:00 to 2:00. With no wind flags, it was a crap shoot.
Note: during the course of my shooting I used various aiming points and made several scope adjustments in between groups.
The first group was with the 250 gr. SST at an average of 2924 fps with a 15 fps ES and a .783” three shot group.
#2 was a repeat of the load after a scope adjustment and it was pretty much the same @ 2929 fps with 18 fps ES and a .845” group.
#3 was again the same load but shot at 300 yards. Av. = 2943 fps with another 18 fps ES. I had added 4 ¼ MOA to the approximate 100 yard zero. Here is where it got confusing? The first two shot measured ½” while sot #3 went off into the wild blue yonder some 14” to the left? Everything felt good as far as he shot breaking. The speed was right there with the others? Yes it was blowing but would have figured it would go to the right? I guess it was a mystery bullet (this is were custom bullets rule!)
#4 I went to the 300 gr. FTX and clicked to 5 MOA (needed another ½ MOA). Here the velocity was at 2801 with a 27 fps ES. The three shot group went 2.270” with the first of four shots opening it up to 5.720”. This can be explained by the wind.
#5 The same load only shot at 100 yards. Here the average was 2783 fps with a large ES of 62 fps? The group being .887”. This confirmed my 100 yard zero. (except for the windage)
#6 I used the 225 gr. FTX at 100 yards and got an average of 2959 with a 18 fps ES and a .650” group.
I shot this with the 300 gr. zero and it printed some 5 ½” high.
#7 was the 200 gr. FTX again at 100 yards. The four shot average = 3039 fps with a 59 fps ES. Had shot #2 been removed the ES would have been only 12 fps. Three shot here measured .950” with all four in 1.5”
Due to the rain, you can see how badly the targets looked. The 300 yard Pittman target actually got blown off.
At the bottom of my sheet it gives you an idea of the velocities obtained with the same load and four different weight bullets.
Hopefully next week if the weather is good, I will be able to give he AerroMax’s a decent test. They sure look badass!
