It was pretty popular. I have a #1B from 1976, and I think the 1A was also in there. Maybe one of the stainless models, too.
I have a bicentennial 'B' specimen as well. I need to play with it more this summer.
After "playing with it more this summer", I have come to realize that this 243 really seems to like IMR 4350 and ordinary 80 grain (Remington PSP) bullets. Sub MOA groups with a 4X scope ..... now I really need to play with it some more.
Sometimes, the air you 'let in'matters less than the air you 'let out'.
