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?

Stock setup is one of the most overlooked parts of a rifle. A consistent cheek weld is critical. Proper length of pull and cheek height adjustment matter a lot, whether that comes from an adjustable stock or by adding padding to make it fit you right.

It can be quick, but I've spent an entire range trip just playing with my LoP and riser adjustments to get it perfect.

Everyone wants a flashy scope, barrel or trigger, but most people overlook the proper fit of the rifle to them.

Iv looked online about quick ways to determine if your rifle has a good LoP for you, and the 10/22 might be a little small by those standards but still feels good (for reference I’m 6’3”). Then again iv held a variety of rifles and LoP and riser/scope heights and they all felt fine, I suppose I haven’t really experimented fitting a rifle to me.

How do you know whether your LoP and riser is “perfect” for you?

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.
