Sight changes

[dale2242]

I shoot 2 loads in my M1.
I have it sighted in for my ball duplication load.
I have developed a very accurate cast bullet but it shoots quite low from my jacketed setting.
I want to know how far my POI will change at 100 yds with 1 click of elevation.
I would like to be able to move back and forth between sight settings with out resighting each time.
Are M1 sights capable of moving back and forth with any repeatability?

POI will change approx. 1" per click at 100 yards IF velocity is the same. Your cast bullets are likely slower so that may not apply. My experience with the previous 3 Garands has been the sight changes are consistant as long as the ammo is consistant. YMMV.
