Default How to find your rate of twist:

Measure it yourself...

Place a patch (oiled) on a cleaning rod and run it down the muzzle. Make sure the patch is a tight fit to the bore so that the cleaning rod turns as it moves down the barrel. After the patch reaches the chamber, reverse directions and begin pulling the cleaning rod back out again - slowly. STOP when the rod starts to turn again, and place a dot on the cleaning rod at the end of the muzzle. Put your mark at 12 o'clock on the rod. (Aligned with the front sight.)

Slowly and carefully pull the cleaning rod out of the muzzle, letting it turn on it's own while watching your mark. When the dot makes one complete turn and lines up with the front sight again - STOP pulling. Put another dot on the cleaning rod at the muzzle, again at 12 o'clock. Go ahead and remove the cleaning rod from the barrel.

Measure the distance between the two dots on the cleaning rod with a tape measure. That will be your twist rate. For example, if you measured 12 inches, your twist rate is 1:12 (one turn in 12 inches.)
If you measure 8 inches between the dots, your twist rate is 1:8 and so on......

Do like Highpower said to be SURE but I believe it's 1-12 or 1-14.

I figured that's what it would be. That means it'll "like" 40-50gr bullet loads.

I assume you reload? If you reload it's not a big deal to buy a box of bullets to try. I'd say 1-14 is at the very ragged edge of stabilizing a 55 gr bullet. You'll have to find that out for yourself. Personally I'd stick with 40-50 gr bullets with that twist.

I think Bear is right about being right on the edge with 55's. With the Swift you might be able to drive the bullet fast enough to stabilize.

I was able to get 55's to group so-so in a 1-14" Swift barrel, but simply dropping back to 50's not only tightened the group, but gives me more lattitude in the powder charge weight to dial in for best accuracy rather than just get it to stabilize. I realize the Swift was made for speed, but I'd rather lose 200 fps. and be able to hit what I want to hit. Just a thought.

I have been reloading for some time and I agree but I was reading a reloading book at a gun shop I wish I could recall witch one it was . It was in there that the 220 could shoot the 70 gr if it had the 1-14 twist thats what made me think it should shoot the 55 . I will try the starter load of 4064. I want to get bugs out anyhow.
