Switching between practice and hunting ammo

[jeedo]

I'm wondering if you have two lots of ammo, lets say a practice lot and a hunting lot, with a lot of zero data-

Does anyone switch between the two lots only with dialing and maybe a few shots for confirmation instead of doing the normal zeroing process between each lot?

I'm going to confirm this anyways with my own equipment; however, just asking to see if I'm missing something or if anyone has experience with this.

In case my question is not clear, has anyone noticed, for example, their hunting ammo is always the same offset from their practice ammo (assuming same lots for both), and returning to the practice ammo it is always the same offset to return to zero from the hunting ammo? So much so that a quick dial and 3 round group suffices for confirmation instead of a 15-shot cone, 3 shot adjustment confirmation, 3 shot velocity confirmation at distance, etc? I don't have enough data to confirm my own findings yet, hoping someone does. thanks.

As far as I have ever observed, yes, it is always the same adjustment switching between lots or different ammo. Thats the whole point—if its not repeatable, its unreliable. if your equipment setup is at all suspect you’d want to verify, but assuming the ammo is the only change, it is predictable.

I do that a lot with my 223 and 6 creed. For 223 I have practice ammo that has cheap 75gr BTHPs and I use 77tmks for hunting most of the time. I also do that for my 6 creed with match and hunting ammo, Just keep notes or write the zero changes on the scope.

I load all of mine so I don't have to worry about the lot to lot issues. In theory it works very well.

Yes, with nearly every rifle.

With my 6.5mm Grendel and 6.5mm CM, I use a lot of the AAC FMJ for 100-yard Carl Ross drills and 200-yard 8” steel. I practice at longer ranges and hunt with ELDMs.

For reloading, for most of my rifles, I have a pile of Gamekings (or similar cup-and-core general purpose bullets) for practice and a couple hundred partitions or ballistic tips for hunting. I’ve also got plans to use cheap bullets for practice and try some monolithic bullets for hunting.

If saving a few cents a round makes me shoot more, I am entirely in favor of it.
