As with anything else, you have to start somewhere. Regardless of what you choose, there will be a learning curve. Many people are happy with the MS. I opted for the LR because I did not want anything mounted on the barrel or rifle. What is best can be subjective.I’ve had my eye on a magneto speed but honestly I know nothing about chronos. If you were say just starting out and wanted to pick up one for load work that was accurate and did the job but didn’t break the wallet which one would you buy? I guess I’m asking which one do you think is the best deal. . Thanks again. I value your input.
