Hammerli 280 Conversion Kit

I am considering a Hammerli 280 with a .32 conversion kit. My question has to do with zeroing my Ultradot. Can I put an ultradot on each barrel and then switch barrels without having to re-zero? If I have to re-zero each time, then I wouldn't be able to use it for rimfire and centerfire in the same bullseye match.

Also, does anyone know how well the 280 will work at the 50 yard line - especially with the .32?

Thanks for the help,

Jacob

It's not easy to mount a red dot on a 280. The problem is that most of the available scope mounts - and there are very few available - depend on using the iron sight screws, and those screws are not up to the task, especially on the .32. The carbon-fiber slide cannot be drilled and tapped, and the screws are a non-standard size, hard to obtain if they break. BME used to make a mount that attached using the more robust muzzle weight screws, but he hasn't made it in several years. In addition, 50 yd. accuracy may be iffy with the .32.

Fred, thatwas incredibly helpful. Thank you very much.

I have a mount from Larrys Guns on a .32 Hammerli 280 and I like it

I have a 280 with both .22 and .32 uppers, red-dot sights mounted on each. As long as the upper is properly installed in the lower, the zero doesn't change (mine has a bolt in the frame in the magazine well and a bolt on the end of the recoil spring guide rod at the muzzle; I believe there were four variants of the 280 with slightly different upper-to-lower mounts, and I think mine is the 2nd variation). I've shot the .22 at 50 yards; I've never shot the .32 at 50 yards -- maybe I'll try it someday.

My .22 cal. unit is a tack driver.  The .32 is a different story.  Depending on the barrel twist, it may be a good 25M gun, but not necessarily a good 50yd. gun.  You will have to test and find out.
