New to reloading and want to buy some digital scales, don’t want to spend a fortune if I can help it ideally around the £40 mark.
Is that realistic? If so what would be peoples recommendations for that sort of price range please?
Unfortunately I doubt you will get the accuracy from digital scales at that price point. I have a set of Hornady iirc branded digital scales at that sort of money (I don't recall when I got them) they are not consistently reliable enough when checked against my beam scales. they tend to get used to weigh bullets or cases not powder.
I Have Lee and Hornady beam scales, I use the later with a home built electric trickler (similar to the Target Master) that is quick (approx 20 seconds for 23gn load) and within a kernel or two weight wise.
The digital scales that give that level of accuracy will cost towards ten times your £40 depending of model. You might pick up a decent set of secondhand beam scales for £40 but some will be more than that.
You can use various methods to measure your powder, be it scoops, hopper type measures, automatic tricklers that vary in price usually in that order. Beam scales when properly set up (as per their instructions) are in my opinion hard to beat, certainly for the price.
If you haven't got any kit yet consider what your use is, hunting ammo, target, is it to load a particular bullet not available in factory? Then you can decide on what kit you need, Lee do the Anniversary Kit that produced ammo with consistently 1/2 MOA or less in more than one cartridge. However if your after the last tiny improvement in bench rest then you buy different kit with tools to create more consistent brass, powder weight etc.
Many start like I did with secondhand stuff (most of mine is) it is a good way to get quality gear at a fraction of the price.
