I also have a Win 94AE Trails End carbine in .357.
I used an Osprey laser bore sighter on my 7x57R, along with a 20-gauge bore sighter, in my combo gun. Bought them on Amazon for about $12.00 each.
The 20-gauge sleevel uses a .223 boresighter, which is good, because I can use it in a .223, 556, or in a other sleeve for a .308 or .30-06.
I also have an inexpensive boresighter which fits into the end of the muzzle, which I have used to regulate a set of rear open sights I filed and installed on my 8x60S. It put me right on the money at 25 yards.
