Has anyone used one of these? I have a regular bore sighter that goes in the muzzle but it's never worked well, doesnt lock up well. I just picked up a new ZF41 rig and looking at these to try and take some of the pain out of sighting it in.

I have a hard time believing that the inexpensive cartridge style could be very precise, but if you’re just trying to hit paper before further adjustment, probably OK ( i have not tried one other than 9mm)

I bought a laser boresighter with an expanding collet style insert for the barrel, so you can snug it into the bore concentrically, & the beam is OK for indoor use. the single spring traditional style arbor tends to follow the rifling, hard to maintain proper over center for leveling crosshairs. I put the barreled action into my tipton best vise and using a magnetic level on the bottom flat of the receiver, then clamp the wheeler engineering kit for leveling the crosshairs to the barrel, rechecking level every time I touch any thing. then turn on previously installed laser boresighter & proceed from there. (both devices aren’t where I am right now, or I’d post their info)
 
I use them regularly. As you say, it will get you on paper, maybe a little better. Much better than the ones that ram down the bore.
 
I probably shy away because the 9mm 1 I bought at a gun show doesn’t chamber in one of my pistols, tho I don’t recall which one. (AND I don’t buy anything thru amazon!)
 
I have the Osprey ones in basically every caliber I own. I've used them for 98k snipers, PU mosins, SVDs, and any other scoped rifle. Just chamber it, adjust your scope to where its right under the red dot on a wall about 25 yards away, and shoot a target at 100 yards. You'll at least be on paper. It will never be perfect but nothing ever is. You'll have to fine tune the zero for sure but it will certainly save time and ammo. I hear those Zf41 scope are about the biggest pain to zero as you can imagine.
 
Hi all. I tried this method to adjust a zf41 too. The problem is that to make zero, you would have to be at least 50m away. But the red dot is too small, it is difficult to see it. I found another tool that works just as well, I adjusted my zf41 with it and it's perfect. As Dragnov says, it will never be perfect,but it saves a lot of time. I will post the link in a following message.
