225gr Accubond and the Ruger M77 358Win

bullet · Sep 8, 2009

In going to the range today and increasing my OAL from 2.882" to 2.885" two things changed. 1. The point of impact and 2. The velocity.

Now the point of impact was a little to the right and just a little lower than the previous load. The velocities came up 20fps faster.

Now two things stayed the same. 1. The pressures stayed the same because the base of the brass expanded the same as yesterday and did not increase. 2. The size of the group ( although I was not pleased with my second shot as I felt I did not do a good job) was the same.

Here is the Target:

Here is the average velocity:

Yep, stopping right here and will load some more to sight-in correctly so as to be ready to hunt with it. I have the same ballistics a a 30-06 with a 180gr bullet but with a 225gr bullet that makes a bigger hole, has more energy and that says it all. :grin:

Wow, you can't beat your first groups of right at an inch and over 2550. That is a sure killer for a long ways. Man, that is excellent. That would be deadly medicine at whatever you pointed it at. Might have to try some TAC. Kind of looks like a really good powder for the 358 Winchester. Scotty

Make sure you start at about 46grs and work up. All rifles and their chambers are different but you are right about it being a good powder.
