I have this Winchester Model 53 takedown in 25-20 that I have never been totally happy with, in concern to accuracy. It's a tack driver with the Speer 75 grainer or even with Hornady 75 grain spitzers with the nose ground down. I won the Regional Silhouette Championship in AAA class with this rifle a few years ago but.....I used the Speer 70 gr. With cast.....well.......I tried about everything and the best I could get was about 1 and 1/2 at 50 or about 3-4" at 100 most always with flyers with the 70 gr. Lyman gas check. Not bad but I knew it could do better.
Special mention should be given to velocity as groups up to 1400 were easy to get good. I wanted to go higher up to the 1600-1800 level for reasons that don't mean nothing here.
The other day I cast up a mess of these same Lyman's using a Linotype alloy and put on a no drill scope mount along with a long eye relief Leupold scope. In the past three days I fired 35 eight shot groups, sometimes 5-7 shots for a total of close to 300 rounds.......all at 50 yards.....all taking my time.
Results? The same as I had with the tang sight.....pretty much the same size group and again, with one or two flyers every 8 shots. Velocities with 6 different powders.....Unique, Herco, 4227, RL7, WSF, and A.A. #7 using different seating depths and varying charges. The slower powders were eliminated fast as extreme spreads were 75-150 fps. I decided to stay with WSF, and AA#7 as these powders had the closest extreme spreads. Winchester small rifle primers were used throughout and yes, in the past I tried pistol primers, CCI S.R. and Federal S.R.
There are other variables I left out and I just don't feel like repeating them here in detail as I'm not getting paid to do this post and there's some stuff on Fox News I want to see later.
So.......I'm scratching my head and then I remember something that brought me true happiness 15 years ago. While working with an original Winchester Hi-Wall 40-82 I found that after I ran out of 41 caliber gas checks, I decided to use .416 gas checks.....a little sloppy going on but the lubricator straightened them up real nice.......viola! Groups went from 5" at 200 meters to 3".
Once again...so.......as I have about every imaginable component down in the gunroom, I decided to try some 6.5 gas checks and double viola.........groups shrank and flyers were in the past! Shot 6 eight shot groups and no flyers.......velocities are a bit over 1600 fps. I decided to stay with A.A.#7 with 6.5 grains.
My backyard set up with the "silencer" in front of the barn. No sound at all if speed kept under 1100 or so. The blast is greatly diminished if going super sonic. This "silencer" is nothing more than 4' of fencing wrapped around egg crate foam with an old water heater insulator wrapped around it with my special camo paint job. It's funneled from 18" to about 9".

Close up.....yea, this cat follows me everywhere just like a dog.

This is very typical of the groups I have been shooting. The one on the left...notice the flyers......then the one on the right......with the larger gas checks.

The dang cat wants in on the action and Twinkles told me not to put any "guns and stupid stuff" in with her.
