.357 Mag sight and accuracy problems
I bought a used T/C 10 inch bull .357 mag barrel for my G2. It appears to be in excellent condition. I tried a few different loads through it and have the following problems: First, with low velocity ammo (4.7 grains of 231 under a 158 grain SWC) the gun groups high, even with the rear sight all the way down. Only one load really grouped well - 5.7 grains of Unique. 140 grain JHP's over blue dot grouped poorly, and this has been one of my favorites in other guns due to its great accuracy. I guess that I need a taller front sight to get the slower rounds centered on the paper - any other way around this? Also, what other loads have provided the best accuracy for others? I'd prefer to stick with Blue Dot, maybe change projectiles - anything between 110 and 158 grains. It's for target use only at this point. Thanks in advance.

Yep, taller front sight. Its set up for .357 Mag loads NOT .38 Special equivalent.

BTW, some one may have swapped rear sights. I think TC made 3, maybe 4 different ones.
