I thought the definition of ELR started at 1,500 yards or a mile and certainly at 2,000 yards.
I'm planning to try 2,000+ yards with my 338 RUM. I know that's not in the same league as one of your wildcats but to say it isn't ELR is kind of petty.
I only mentioned the costs of 6.5 Creedmoor to illustrate the range of costs going from a good and affordable long range round to an entry level ELR round (338 RUM).
I have an idea of what .50 BMG costs to shoot and it's more than 338 RUM even if you use surplus brass, bullets and even pull-down powder. If you step up to match grade stuff it gets pretty expensive but probably still cheap compared to an ELR wildcat with no parent case.
The point I was making is that these no parent wildcats are expensive and reusing brass more than 10 times is great but doesn't make them cheap.
I wasn't comparing anything to .38 Special reloads made from recycled wheel weights, dont make it seem like I was doing anything beside commenting on cost
