Boresighting Thompson 50 cal
 

Hey Guys,

I put a Nikon BDC on my Thompson 50 cal Omega today. What's the best way to boresight it? I was looking into a boresighter and I see Cabelas has a numerous calibre but I didn't see a 50 cal. Can I use a different caliber? I need some help and I know the great people on this sight can help me with their wisdom...Please help me...

Personally , I don’t think you kneed to buy anything. All you have to do is, place the rifle on a cradle or stabilize it on sandbags so it doesn’t move. Remove the breach plug and keep the action open so that you could see thru the barrel. Place a target at 25 yards. Hold the rifle steady o/c of the target and then dial the scope to the same location on the target. This should be close enough to hit paper when you make your first shoot. Then it’s just a mater of finishing the job... Good luck.

Agreed, I have a laser boresighter, but for larger caliber looking through the barrel at 25 yards is good enough to put you on paper.

Make that X3. Spend your powder (money) on more powder amd sabots and such.
