Fair enough. For load dev. would it be a good idea to buy in small increments first? (100 bullets, 1lb powder, etc)

That seems like the most logical route. Are different lots of components different enough to the point of being accurate for one and inaccurate for the next in the same rifle? Might be an irrational thought but it’d suck to work up something good and have it backfire when I tried to purchase the same stuff in bulk.

Thanks,
