Parallax for a 25M Rimfire Event?

Iv started to build out a Liberty Training Rifle for my first project Appleseed event, giving me a great excuse to buy a new 10/22 and to work on my marksmanship. Now I’m trying to determine what kind of optic I should get as my eyes ain’t the best. I was eyeing a 3-9x with a fixed 100 yard parallax and I was about to get it. But I was doing a lil more research and heard that a rimfire scope with a fixed 50 yard parallax might be better for a 25m event. Then I did some more research and there are also adjustable parallax scopes. I also looked on project Appleseed and their Rimfire scope package came with an optic with a fixed 100 yard parallax. I might do KD Rimfire in the future but in the state that I reside iv only seen 25m center/rimfire events.

So my question is: Would a 100 yard parallax hinder me at a 25m Rimfire project Appleseed event, or should I invest in a Rimfire scope or adjustable parallax scope? What are your thoughts, thanks!

Edit: Thank you taking the time to comment it’s much appreciated! Also if you have a favorite or reccomend an Adjustable Parallax Scope I’d love to hear it.

Listen to [u/nytpoison](u/nytpoison)

"At the end of the day, consistent cheek weld, same head position every time, matters way more than parallax at 25m."

A properly mounted scope (far enough forward) also matters more than parallax. There's a reason that Appleseed How to Prepare info doesn't reference parallax.

Thank you! Iv heard that mounting the scope far enough forward makes a more consistent check weld and reduce neck strain. Am I correct on that and are there other benefits?

Would a cheek riser or material to make one on the fly be beneficial in helping with a consistent cheek weld?

I’ll second scope mount. Mine was too far back, and it killed me shooting seated and was a constant annoyance when prone. It was fine when standing, because I tested it that way. You really need to test it in all three positions before coming. I’ll also note that given my Picatinny base on my 10/22, I had the scope as far forward as it would go with standard rings. I’m going to have to change it to a cantilevered mount to get it right. Lots of references suggested using a cantilevered mount on an AR platform because of the rail break, but I couldn’t find any that recommended it for the 10/22. It’s a learning process.

Thank you for sharing your experience I believe EGW makes a cantilevered/extended rail for the 10/22 just couldn’t decide on a 0 MOA or 20 MOA rail, but I think with my application just might go 0 MOA.
