I'm getting ready for my first ever race weekend in three weeks where I'll be trail running a loop x five and with four shooting stages. Around 6 k total distance.

I have been training with CCI SV rounds (the "cheapest" that my biathlon friend said to use in training) and have shoot close to 700 rounds in my new rifle over the past two months and I get decent groupings.

I have a brick of RWS Target ammo, which is supposedly a step up from the CCI, and he said to use it for competetions.

I sighted my rifle in with the CCI and can group with rounds grouping within an inch when shooting on a block.

I am curious as to how much you often have to re-zero with a different type of ammo.

Is it usually just a few clicks up/down and right/left or is it really large changes, all things being equal on an indoor range with climate control (I know that wind, humidity, heat/cold can make changes in between days even with the same ammo).

Thanks in advance for any helpful information from your experience.

I'm thinking of going to the Gatineau Loppet in 2027 and I'm just starting to pursue my Gold Masters passport and I see that the Gatineau race has a 50K Classic and a 50K Freestyle as well as a 100k combined version. I'd like to do the 50K freestyle race but would I have to do the 100K version to qualify for the stamp for the Gold Masters from that event?

Thanks for any helpful information and Ski On!
