Since I've been collecting and shooting Milsurps for over 40 years, I load for close to 70 different calibers from 5.45 to .577 to feed arms from Sniders and Spencers to AR-15s and AKs. Were it not for reloading, there are far too many rifles and calibers that I'd never have been able to shoot.
There have been times when the supply of even common calibers has been short to just not available and for the less common and odd-ball calibers, that is the case most often ... or always. Remember some years back when we couldn't find surplus 8 X 57? Remember the day you found out that CMP had burned through nearly all their totally clean .30-06 and annual purchase limits were imposed? How about the days of HXP .303? When have you seen .236 Lee Navy for sale? How about .276 Enfield or 8 X 58R Krag? We have Privi today and while it's not cheap ... it's available! If not for them, where would you find 6.5 and 7.7 Jap or 6.5 and 7.35 Carcano?
Reloading is a godsend and while now may not be the best time to plunge into it because of component, powder and primer shortages ... my thought is that if circumstances permit, you should take a second look at it. It's not rocket science and it's safe! There are reloaders near you, when you're at the range, just ask around. They can help get you started with hands on experience. There are dozens of good books (The ABCs of Reloading and the Lee Reloading book are great sources of basic information) and good, safe reloading data is everywhere.
As an aside, reloading expands your shooting hobby into the off-season (for those of us north of the Mason-Dixon line) and there is nothing quite like taking your first batch of ammo to the range, loading your Milsup rifle and pulling the trigger. The BANG that follows is something you will NEVER forget!
Gotta' go now, I have quite a few boxes of fired brass that need reloading before next Spring!
