Default Thick & Thin Sabot

On the other forum, there has been an ongoing discussion of whether the black sabot are more accurate than the green sabot. Having been away fishing, i felt an urge to shoot, so i did.

This morning 3 different bullet, and 2 different sabot were shot. The rifle was the Mountaineer. The load was 110g BH. Primer was W209. Range was 200 yard. The rest wasn't concrete bench solid, but it was decent with just a tiny bit of cross hair movement. The first shot was taken when there was so so very little breeze on a cold clean barrel; it is marked 1. The temperature when the first shot was 60*. The temperature when the last shot was 65*. A breeze started after the first 10 shots. The aim for the first 10 shots was the lower bull.










The first shot was a 270g Deep Curl in a green crush rib sabot. The second was a 300g Deep Curl in a black crush rib sabot. The third was a green sabot, the fourth was a black sabot, etc. This went on for the first 10 shot. The holes dyed green were punched using a green sabot. The black holes near the bottom bull were punched using a black sabot. The barrel grew warm during these shots, but could always be grabbed and held. Reloading was done casually with no hurry.


After taking the 10 shots at the lower bull, the bullet was switched to a 44 caliber 300g XTP, and the aim was changed to the top bull. The breeze kinda picked up, but was intermittent. Six shots were taken. I think the shot wild right was the third. That shot ruined the group, so i took a sixth. This made for a prettier group measuring less than 3 3/8", if one mentally tosses the wild right shot. At the time, there was a gusting breeze, and the barrel was quite warm.

The first shot on the cold clean barrel was quite much out of the group. If one mentally tosses this shot, one sees a nice tidy group of green measuring 2 3/4".

The green sabot sure did better this morning than the black ones. I wonder why? Yes i do.
