Three of us tried the T7 and got the delay. I was at the gun shop where we bought the 700ml and we were not alone with T7 hang fire in a Remington 700ML. None of us us T7 now, we all went back to Pyro 50gr pellets. This years ML season we shot 7 deer and one yote, we missed at least 6-8 shots with no hang fire. My Pyro pellets are 4-5 years old and I have never had a problem with Pyro. One of our group sold his Remington because of cleaning time, four of us bought them and now only three of us use them. One of the three sold his also and bought an Encore but found that it did not group as well as the 700 so he sold the Encore and bought his 700 back from his friend? They are a bit harder to clean and not made anymore but for 6 days a year it shoots as good if not better than the top of the line ML's. Our grouping got better using the CCI 209Mag primers. I have also used loose pyro with no hang fire on the range but not enough in the field to test it under all hunting conditions.
