Premium grade bullets whether they be partitions, bonded core or monolithics are somewhere between £1 and £1.50 each depending on brand, who you buy them from and size.
Then a Kg of N140/N160 powder is £130. 1 kg is a bit over 15,000 grains and at 50 gr per load that’s 300 cartridges or 35p per cartridge. Add 10p primer and say 30p brass cost (£1.50 for norma case, 5 loads). You are looking at under £2 to £2.50 a cartridge.
Yes cost of dies and press, but those are capex costs and will be recovered if and when you sell up.
I bought a complete reloading set up off a retiring shooter 15 years ago for £100. I could sell it now for more. Ditto with dies.
Alternatively spread the cost over reloading kit over 500 or 1,000 cartridges - add 50p to £1p per cartridge.
On the flip side you can remove the cost and time of a round trip to the gunshop every time you need a box or two of cartridges. I can load up 50 cartridges in a couple of hours - similar sort of time in going to and from local gunshop.
I don’t add the cost of my time. I am doing it as a hobby.
However, and its a big however, you can very quickly go down a rabbit hole of chasing group sizes. It’s not difficult to get a perfectly acceptable hunting reload - ie something that will allow you to hit an iphone sized target easily at 200m - ie a Minute of Angle, and to do so within 10 to 20 shots (or fewer if you mimic or use factory ammo load data).
But if you want little tiny clover leaf type groups - you might get lucky, but you can burn through lots of primers, powder and bullets trying to reach perfection.
