Default 1903/A4 Shot Stringing

My 1903/A4 build has been stinging shots vertically. At 100 yds, a six shot group was about 8 inches. Windage was pretty good. Lyman Alaskan scope. Bedded under the front band about a year ago, and should be well settled there. My question is how much tension on the rear tang screw would you recommend? Thanks in advance as I won't be around again for a day or two.

Get the front action screw tight. Snug the rear but don't kill it. Does your stock have the little steel tube in the rear through which the rear action screw is inserted? Sincerely. bruce.

stringing is usually stock fitment issue.. pushing or binding in the stock.

Hi 2908,

Have you checked for free-floating of the entire barrel?
Both in the stock barrel channel & the hand-guard, wood can & do move.
How tight are the barrel bands? I had that problem early on!

I know you mentioned installing a pad under the band. From what I know about the 03-A3 some barrels like to be totally free floating or some rifles need a small pressure pad about a 1/2 inch wide -light up pressure- on the TIP of the stock!
I have one 03-A3 rifle barrel set-up of each type mentioned above.They do shoot better then I can shoot them. My pal & I used them at the CMP SPRINGFIELD vintage match this year.

Good Luck,
broom

Have you tried shooting it without the handguard?

It's a Keystone stock, and the spacer is present. Will make those changes and post the results in a few days. Many Thanks

Hi Chuck,

You know what your talking about your a proven pro! I'll write that tip down.
I never thought to used grease, I'm sure it works, but I'm messy to start with.
I usually ask for last years out of style lipstick. My pal (80 +) still uses carbon black from a candle flame or carbon sight blacking tool.
We can reach the correct answer by various proven methods.

Hope all the methods & thoughts work out for the OP,
broom

I have inletted and fitted a few stocks on 1903 and 03A3 actions. I like to use the dollar bill method to see that there is no binding whatsoever during the inletting phase. Of course, you have to tighten the guard screws down to do this.

Take a dollar bill and slide it under the barrel at the end of the stock and then work it side to side as you pull it toward the receiver. Where it stops or binds is where you might need to remove some wood. I use a round rasp for inletting which came in a stockmaker's set. Go slowly and check often.

When you have a completely free floating barrel, do some test firing and see how things group. Then, if you still want to try it, shim the barrel at the forward end of the stock with cardboard inserts and see if there is any improvement. If shimming helps with accuracy, you might then do some glass bedding in that area.

Check any issue stock to be sure that the metal screw channel is present. If not, they can be had very inexpensively. I don't know how much they affect accuracy (each rifle is different), but I can tell you that absence of such a piece is a leading cause for cracks and splits in the stock's wrist.
