This is truly insane!

After all the topics latley about accuracy being better at long range than short range.

Today, I went out to test the BC for the 155 AMAX out of my gun. Not carring about precise accuracy, I wanted to see how good the BC was or not. So I zeroed my load at 300 yards. 1st group was 2.5" the follow up after making an adjustment was 4.675" After being zeroed I went to 600 yards, where the group was where it was suppose to be with the BC I had guessed at. This group was a whopping 5.875"!! Pretty bad huh? I decided to see if the BC would hold to 1k. I fired 1 3 shot group. I drove to the target and after looking at it, I couldnt belive it. It was 3.5"!! I thought no way. That was a mistake. I went back to 1k and fired another 3 shot group. I couldnt get an accurate size becuase 1 of the bullets just grazed the side of the box, so I can only get a close measument. It was about 4.5" Crazy I tell you.

If you look at the pictures closley, you can see the bullets starting to key hole. Yes it is crazy. As you can see in the picture, I turned the box 90 degrees to the first side I shot, so as to not corrupt the 3.5" group. I also made an adjusment to the right. I put an arrow by the one group to show that thats where the bullet had gone by within .125-.25" of! Also you can see the steep downward angle of the bullet!

Also the BC I have come up with is between .474 and .484 out of my gun. Still need to fine tune it, but its no worse than .474 out of my stick.

Re: This is truly insane!

I thought the box specs. said theat they were.475 BC, or maybe that was Midway. What did you think the BC was? [img]images/icons/confused.gif[/img]

Re: This is truly insane!

The factory states that the BC for the 155 AMAX is .460 It of course can change with indavidual circumstances. It appears for my circumstances that it is around .474-.484 I am going to do more shooting tomarrow to iron out the details.

Re: This is truly insane!

Michael,
Nice shootin!
I saw the green arrow there, but no hole??, then you said "the steep downward angle", then a saw the arrow was pointing to the spot the bullet passed as it made a gash across the cardbard there!!

I emailed you. I'm heading out in the morning, fog suppose to lift tonight. Should be perfect chrono weather tomarrow. Maybe we can set the 35P down at the target and get some BC's from it and the M43...
