Costs for me is not the primary benifit to reloading ..
If you would like to see a genuine shrinking of your groups..across the board improvements in your marksmenship.
Learn to reload..
Learn to do it properly.. Don't max stuff out thats how things break and people get hurt. Keep detailed and accurate records of what you are doing powder. primer. bullet weight, number of times cases have been fired (If you know) on the boxes as you make them and in your Shooters Notebook.
How do your learn? Start with some book knowledge on the basics plenty of books on reloading ..

Under Supervision, I was casting lead bullets when I was 12 and loading on my own before I was 15 , So how do you find someone to teach you at an older age..
Best guess... I would join a reputable gun club (there are a lot of good reasons to do so) and just hang out for while.. Eyes and ears open.. There are a lot of types there and you will have to ferret out the clear eyed sober fellas of a serious mind if you really want to learn properly.. Then find one that is willing to take the time to teach..The basics are simple.. straight forward but there are lots of subtleties to the craft..part of the fun is discovering some of your own secrets once you have the basics down pat. (I just cannot get that crimp right). Cream of Wheat? No I am not hungry...What? Where? (Smile.. Big Bore).
You have a Shooters Notebook right?. If not start one now.. Write in it the weather, wind, cloudy, temp .. how you feel.. what you last ate.. Coffee? did you sleep well? All that affects your shooting as well. How your day went at the end of shooting. This is a part of the process..
Consistancy, replicability these are among the "Shooter's Secrets" They are among the benifis of reloading when done properly.
Start shooting precision loaded ammo... see what happens.. If you are consistantly doing your part in the weapons handling department. You will shake your head and say...."Holy Cow!!!" Wish I knew this long ago.
When you reload.. No distractions.. No TV, No Talk Shows.. No Chit Chat...No "Beer" and or Nachos..
Be fed a while back, wll rested in a good physical and mental state and stop loading long before you get tired or distracted. 45min is probably good .. Set up time , Loading , Clean up... This is a serious discipline and you need to treat it as such.
When and where ever it comes up say this to others up front...
" I do not shoot other people's reloads I am not offended that they do not shoot mine" I do not provide my reloads to others for the sake of liability"
Just get it out there up front before it comes up...... Saying you are not offended that they do not shoot yours is really just to soften the statement make it non confrontational it helps..
Shoot only the stuff you personally reload.. Weapons are costly..Injuries terrible or worse... You cannot control the safety and condition of other people's weapons (Some could be ready to dissasemble with the next factory round fired) So do not provide others with any of your own reloads under any circumstances..
Exceptions make the rule and if in 4-5 years you find yourself with a buddy or two and a row of Dillion Progressives loading a couple thousand rounds for the weekend festivities for the 100th time.. With the fellows you have known and shoot with for the same amount of time or longer.. When you get there make your own call.. even then think long and hard about it. Still do your part to keep your reloads within the circle of those makeing them.
For now and the next few years... Stick to the rule..it's a good one. Learn the craft yourself.. and don't provide people with "a few of your reloads" . There is no upside and the downsides are real..
