This is for the designers of the sights on the H001 model specifically. I have had this rifle for a couple of years and recently began preparing it for use in the local Rimfire Silhouette matches. These are shot with iron sights at about 55 yards against various sized spinner type steel targets. The smallest is the chicken, which is about 2" in the longest dimension.
I gingerly filed the front sight so the rifle would zero at 50 yards with high velocity (1250 fps) 22 ammo. I sorta made a mistake and used Remington Thunderbolts to do this, so 3 out of 4 shots are right on, while the 4th may end up nearly anywhere on the target. Still, the Henry runs these very reliably, and they are accurate except for the individual shots that aren't . I found Federal Auto Match and Norma Target also shoot well, with less variability in accuracy.
The rear sight adjusts for elevation via a notched ramp with 3 different elevation positions. I zeroed the HV ammo for the lowest notch and figured I'd just take what I could with standard velocity ammo. Well wouldn't you know it, the designers at Henry figured it out for me. The notches move the point of impact about 4 inches at 50 yards. Here's the magic. That just happens to be the very difference between HV and SV ammo at that range. Notch 1 and I'm grouping HV ammo right above the front sight. Notch 2, and lo and behold the SV ammo hits just above the front sight at the same distance. I have not tried this I bet the third notch will put hits just above the front sight at 100 yards with HV ammo. I have a set of peep sights to try if that becomes necessary, but I plan to shoot the next couple of matches with the factory sights and see how it goes. The Norma standard velocity ammo is slightly more accurate than the Auto Match, so that is the preferred fodder for the time being. For whatever reason, this rifle does not like CCI Mini-mags or CCI SV ammo. It's ok, but the Auto Match and Norma are ahead. It also likes Aguila Red box Super Extra HV pretty well too.
Good on Henry for working this out ahead of time so I didn't have to replace the sights right off the bat.
