Switching from Prvi .223 match 69gr to M193. POI shifts?
Anyone happen to go from shooting .223 Prvi match 69gr to LC m193 and notice the difference in point of impact? Coming from a 16" chrome lined brl with a 1/7 twist.
Going to be using the Prvi Match ("Poor Mans TAP") as my HD round but only plan on getting 220 (7 mags and 10rds to zero) rounds of it so Id like to know what kinda changes Id run into if I had to make the shift to M193.
It shoots closer to 62 grain than 55 grain in all my rifles.
I have my Colt LE6920, AUGA3, and FS2K all zeroed with 62 grain IMI
The Colt shoots the 69 Privi real close to POI, the AUG puts them a tad left, the FS2K puts them right I think so the proper answer is they are gonna probably be off a couple inches at 100, at 50 maybe not enough to worry about.
I have some pics. At 200 yards with the same zero. Slight variable wind. 18in barrel, 4x urban ninja tactical scope.
The 50gr bullets shoot about 1 inch left in my rifle with it zeroed to 62 gr. The 77gr shoot about an inch to the right. The 69gr about a half inch to right.
If you start at 25 yards with 3 shots to zero you should be able to easily zero at 100 with the remaining 7 rounds,
Every rifle is different. You can obviously expect the bullets to hit lower, but where exactly? Only way to tell is to try it yourself...
