I've been kinda into them for quite awhile, not for competition, just general plinking.
I bought this 40-X back in the 80's, manufactured in 1973.
I also bought a ultra rare Remington 40-XR repeater back in that same time frame. They only made around 700 of them. I ended up selling it, as values were going sky high, & I was afraid to take it out of the safe. I've got pics somewhere of it.
Also had a Remington 541-S once upon a time, but sold it too.
Sold my 1973 40-X barreled action, that was in the McMillan orange stock, & picked up a Vudoo barreled action to stick it in.
Didn't keep that one very long, as it had a match chamber, & I didn't want to feed it the good stuff, so down the road it went.
I replaced it with a Bergara BMR, great gun.
Liked the Bergara so well, I bought a Bergara B14R barreled action, & stuck it in a Manners EH1. Love this one.
