I went to the range today to do some work with the 257 STW and the 270 WSM I have been working with for other people. I have had some serious difficulties with the 270 WSM, but I did have one load today that shows promise, and I'll focus on it for the coming week. The 257 STW is a Browning High Wall. My first series of loads, using Accurate 8700 and 115 grain TSX, yielded groups between 0.70 to 0.75 inches. It was consistent across the charges tested, which was most gratifying.
I took my 257 Roberts with me. I'm still in break-in for this rifle, so I really wasn't expecting much with it. However, the first load fired gave me a start. This is three shots at 100 yards. Velocity is not what it could be, but the accuracy is pretty good.
I'll definitely be working with this rifle some more.
Here is a closer look at the group.

Whilst shooting, I was asked to take two delightful rifles just to prove they go "bang." The first was a Mossburg 30-30. It was delivered to the smiths with the complaint that it was shooting a foot and a half high. I printed three shots at 70 yards with rag-tag ammunition into a group of about 2.5 inches, pretty well where I aimed. I think the owner needs to get comfortable with the rifle. The other rifle was a Model 92 that had a barrel reline. Chambered in 44-40, this was just serious fun to shoot. At 50 yards, it put all the shots on paper. I'd love to have this rifle just to work with. However, it did go bang, and it was fun to shoot.
