As with any of our loads, we offer test packs. Our test packs are a mix of different load options, combined to make a box. Typical test packs have 5 rounds with 4 loads or 10 rounds with 2 loads to make a full box. We can also do seating depth or charge weight variations to dial in a load to your rifle. The Test Pack is a great way to see if your barrel likes a particular load without having to buy full boxes. Pricing is based on which loads you choose.
