I have tried them in three different rifles and they have all been exceptionally easy to get shooting tight groups in a very short amount of time and spent cartridges. With the current availability of bullets and other reloading components this is a big plus. To date I have only taken antelope with them but they worked flawlessly. The owner of the company will pick up the phone when you call or get back to you on an email and help you all he can with load development and recommendations. Its hard to find that in any industry anymore. My suggestion is to give them a try, I do not think you will be disappointed.
