There is no simple yes-or-no answer to the "should I start reloading" question. In addition to the cost of a reloading setup and components, you need to factor in the time required to reload rifle ammo (far more than pistol ammo due to brass preparation) and how many years you have left to amortize the cost of your equipment.
Regarding time required: for precision rifle ammo, these are the steps required. Each step involves one or more pieces of equipment you'll need to buy.
- Clean brass - requires a tumbler and some kind of cleaning media. Bigger tumblers clean more brass per unit time. I use corncob media in a 1970s-vintage tumbler; takes about two hours to get nicely clean. Note that gas guns are going to spew out dirtier brass and that some people feel that a lot of cleaning is unnecessary.
- Deprime/Resize/Reprime - Requires lubricating the fired brass, then run the brass through the resize die which deprimes/resizes on the downstroke and allows repriming on the upstroke (some people reprime as a separate step; I never have).
- The upstroke can also pull a neck-size button back through the neck; some people prefer to use a neck-size mandrel as a separate step.
- Clean the lube off the brass. Some people use their tumbler to do this, or a separate tumbler. I have my own manual method but it's lengthy; I'm retired so I accept the time hit.
- Trim. Bottleneck brass grows in length with each firing. I trim every firing. Others don't.
- Drop powder charge in each case. Scales range in price (for decent ones) form maybe $75 for a good beam scale (slow) to several hundred or more for laboratory-grade scales.
- Seat bullet.
Left out: annealing brass. Each firing work-hardens the brass. Annealing releases that work stress and makes brass last longer.
Dillon Precision has
cost calculators that can help you find accurate per-round costs and break-even costs. You can get component costs from any of a zillion different places and plug into the calculators.
Regarding brass: You don't say what your goal is beyond "match ammo." I bought 1000 Starline cases two or three years ago and I'm on my 8th loading or so for 700 pieces (300 pieces unopened). These are for my bolt guns. I have little interest in gas guns beyond occasional playtime; I don't waste my decent brass for this - I have cheap once-fired range brass I pick up after a mag-dumper leaves. I also don't compete with my .223s; for my match rifles I use better brass like Alpha, Lapua, etc.
Yes, reloading is a very deep rabbit hole. I've been doing it for over 50 years, so my gear has long paid for itself (my newest press, a Dillon RL-550, was purchased in the mid-90s). The longer you do it, the more you learn and save.
Some people love it. I do it because I get best performance from my rifles, but I see it as a chore, not a hobby.
