I reload now for both my .222’s but when I started I bought 200 rounds of sako 50g sp’s, both rifles ( Tikka m590 and Cz527)loved them so when I’d shot the factory rounds I used the brass to reload 40g v-max which is my vermin round, now I always have 5 or 6 boxes of factory in the safe just in case, I must over the years have shot many hundreds of them without a single problem, as an aside I was in Devon last week and popped into lads guns at Crediton, they had 11 boxes on the shelf, as a bulk buy price I was offered them at £18 a box so I bought the lot, it’s a win win for me as I will end up with another 220 fire formed brass, PM your number for a chat, if you are close enough and you decide you’re not happy with them I’ll have the remaining rounds off of you ?
