Well I pulled out the No.1 Lott from the safe last week. It had sadly been a while. Here are some targets shot from the bench with express sights.

The first session was quite the learning experience. Suspecting that I had previously sighted the rifle lacking decent precision I decided to revisit this. You can see two different points of aim correcting for the high first impact. Starting from essentially zero it was a journey to rebuild a bit of recoil tolerance.

The second session confirmed the high POI and the need for adjustment I corrected the windage at this point as well.

The third session reaffirmed the necessity for a properly contrasting target and also focus. Yes, that's a flinch flyer off left that reminded me not to shoot this gun until I'm physically ready. I took the aggregate impact data and made calculations for sight height adjustment based upon the three sessions. A 17½" sight radius with 4-5" high at 100 yards meant an adjustment of 0.020" to sight height. I ended up changing the rear sight for this.

The last session at 10 yards off the bench. This POA was chosen due to the shoulder profile giving a repeatable aiming point. This is three 400 grain loads and three 500 grain loads fired one after the other pausing only to spot the impacts. The 500's came in slightly lower and tighter with a double impact shared between the two different projectiles.
The allure is renewed.
