Looking to get some repair target centers for my informal practice with old rifles and open sights and was wondering who sells them at a good price.

The MR-52C 200 yard slow fire is about the right size bullseye and Midway sells them for $14.99/100 but their shipping is $8.39 for a stack of paper. Yeah, I know , but please don't start ranting about Midway's shipping. Some other places I checked charge even more.

Anyway, figured you guys could steer me in the right direction to finding the best price for these or other targets.

I have used this place in the past:

I'd go straight to the manufacturers. The two old time companies are American Target (Co) and National Target (MD).
I've always ordered from American Target in Colorado. They were always great to deal with;

The newer company back then (20 years ago) was Speedwell out of NJ. But I never had dealings with them, so can't tell you much.

I've always bought targets and centers for my club's CMP program through Speedwell. They seem to be just a little bit cheaper that National Target.

If you drop me a note to remind me, I'll check tomorrow, as there's a huge target company here in Md near Frederick. Makes all the targets for the NRA around here. They might also know of a printer nearer to you.

See someone else already directed you to National, but I can ask them about the shipping etc. Looks like no amounts under 250.

Target Barn. But don't order their pasters.
