Multiple loads and zero

[mroels]

How do you guys deal with zeroing your scope when you have multiple loads? Do you guys go hit the range and zero and then get going? Currently I zeroed my scope for my pet loads in each rifle. If I develop a new load due to scarcity of product, trying something new, different shooting environment etc etc. When I settle on a load, in my logbook I'll write what mil adjustments I have to make from the scopes zero to hit the bull. Is that pretty much the common way?

ive never had a problem with it being so far off u need to re zero it, how far out do u usually shoot?

I have some loads that shoot to the same point of aim(or very close) using different bullets/powders. So those I can change without doing anything to the scope.
Others if I change loads I go to the range and rezero the scope for the hunt.
These are all hunting loads with K.I.S.S. hunting scopes.
I keep a list of what loads interchange and also what loads each rifle/pistol is zeroed in with.

The question is more geared towards medium to long range, going anywhere from 600yds with .223 to 1k with .308. I don't shoot for groups at distance, just hitting steel.


For plinking ammo, or any ammo that stays within 200yds I wouldn't worry about this.

I do have loads that have same poa/poi. I don't hunt but I would definitely rezero for whatever load I'd take in that instance.

Once you have your loads developed, it should take 1 cold bore shot then 1 more to zero it. Just write down what adjustments need to be made for each load.

I always write down how many mils to dial from powder to powder, bullet type to bullet type etc etc


also known as going back to your DOPE

Yes I have a good amount of hard dope on all me loads including cold bore, clean bore, adjustments at 50yd increments under different weather conditions. But every time I gather data I will always zero my scope for that load and then walk off all the distances to confirm soft dope.

@Exodus - do you zero for one load and then write adjustments from powder to powder etc? That's what I do. Right now my scope is zeroed for my favorite 168gr load, and all other zeros are adjustment written from that zero

I only zero with the most common load I shoot through a particular rifle.
If I develop a different load, I shoot it at 100uds to determine the zero offset.
Then, I build a profile for that load in my ballistics program and I include the offste.
Then, I just let the ballistics program correct my soft dope for the different load...

Pretty much
But I'm still doing my nodes to see which powder I'm sticking with

Post your 300yd groups.
100yd groups are useless.

I usually zero with the bottom charge weight or the middle of my charges (shooting 43.0 to 45.5gr I zero with 44.0gr charge)


You could just use the zero from another bullet or load but don't be surprised if your POI is off by a bit. It sucks.. Ask me how I know haha


Did a OCW test and zero was way off. Pretty much a waste of 35 loads. Had to completely reshoot the test.
