I posted previously about a like-new 1975 Remington 40XBR 222 I just acquired, yesterday I shot 5 shot groups with 1970’s vintage Sierra 52g hpbt and Sierra 53g flat base bullets, both were marked “ benchrest “. I also shot a group with 52g Berger Target bullets. All the loads were 21.0g N133 with 7 1/2 primers. Preliminary results but the Bergers will certainly get more load development. This was the first time I ever shot a Remington factory 2oz trigger- can’t imagine a better trigger on a bench gun.
