Csparks1106 asked me to post his picture of his group he recently shot in his .300 Savage. Also he sent me this PM.
Here's the info from my chronograph. I can't seem to get a picture copied of the target but it was a cloverleaf at 100 yards.

If it was me I would clean your bore with Automotive chrome polish before shooting another group. Also 2" groups with cast bullets is an acceptable accuracy level for a hunting rifle. I've also found that holding the forearm when bench testing cast loads sometimes helps to tighten groups. Those bullets are moving slower but generally recoiling well because they are heavier. Just something to try.
Another thing to try is .5 gr of kapok fiber over the powder charge.

The bullets were all cast at the same time. They are sorted by actual weight. These are in the 181.6-181.9 grains grouping.
The Winchester cases were the ones that I had the stellar results with. I have those ready to load. Before I try anything else I'll try the Winchester cases but I'm wondering if my scope may not have taken a crap on me. It is an older Burris 3-9x40. Ever had that happen before?

Not wonderful like your first group but as good as a lot of very reliable hunting rifles. I'd try some Remington cases. Also,was it the same batch of cast bullets?

I didn't bother measuring the group. The group that was in the first picture I sent you was bottom right of the target. Today I was aiming for center bullseye of an identical target. I was hitting top row and 2 inches right. The group was over 2". The Winchester cases are ready to be reloaded, but today has me wondering.

So what have been your successive group sizes?

Ok, theoretically speaking how much of a difference would different cases make? I had loaded my original rounds with Winchester cases but that was all I had. I loaded another batch with Remington cases and my results were dismal at best. Nowhere near on target. I was wondering if it could be the cases. Here's the chrono results.

Thanks for that comment Zero. I do love that rifle. I wish I knew how old it was.

Very nice rifle and outstanding handloading results.
I would love to have a model 99 but the one's I've come across were too beat up or too expensive.

Shasta, thank you. I like to think you're right. Who knows, it may have been his calm that helped pull the trigger. But I agree, he would be proud.
Ethmoid, I appreciate that. This is my first experience with cast bullets in a rifle. I've been casting handgun bullets for awhile now but no rifle until now. I'm really excited about this.

Yep, I was doing it from my Ipad at home. I don't have a PC or laptop at home. I had to come to work to do it.
