The 6x38 works very well on a short action Rem 700. To use it on a Win M70 FWT short action, I had to use a reverse front Leupold base. It's all because of the long taper of the front tube and the short eye relief. Optically, they are just a shade below the Leupold FXII 6x36, but I like the Weaver duplex better than the Leupold wide duplex.

I no longer have any 6x38s but do have several 4x38s. They have a little more eye relief plus they work really well on a .22 rifle. Parallax is set at 100 vs 150 for the Leupold.

Here's the rub: try selling a Weaver vs a Leupold. I like the Leupold best. It is a slim, and trim rig. Much smaller than the Weaver. Resale is better too.
