Thanks for posting your test results!!! Very generous with your time!!!

Thanks Again and God Bless!!!

It is my pleasure. Lately it has been more difficult to make the time and find a good spot to test. I think I should be good now for the next few months.

I also have a set of loads ready for testing with Accurate No5 powder. Sunset is around 8:40 now, so I will definitely be able to get out within this or next week to do some more testing. Will keep you posted.

Yesterday I tested the AA5 loads fir this bullet. The aim was the same. Try to get to 1150fps, and an accurate load.

I have to decide if I want to go higher with the powder charges, but based on the velocity results, it did not reach the 1150fps goal. There was some good accuracy, but with the lower charges. The grouping started opening up at the higher charges, so I'm not sure if I want to go any higher. More research will be required, but for now I will probably try different powders.

Interesting testing day. As I was getting ready to fire the first shot, I couldn't find the dot for my Romeo red dot. After trying a few things I decided to change the battery. Luckily I had a spare battery with me. That solved the problem. Now I had to find the correct glasses for the day. I settled on my TV glasses since I see the dot a bit bigger, but the target is more in focus. Seemed to felt the most comfortable on the day.

Now the testing. Since the focus is always a compromise, I think I am happy with the results. They are all basically within a 2" circle at 15 yards, except for the last two loads, and the POI is good. Here are the results:
