[QUOTE="VinceMule, post: 3044849, member: 122164"] Yes, that is it. N500 series have 20% DNT. Again, the shot strings are not the big deal, the Heat generated upon ignition is the big deal. The barrel is going to be very hot on any five-shot group. I could measure .012-.020 leade growth on every 50 shots fired with my Swift. 1500 will be a stretch, to say the least. I got 800-900 using IMR 4831 in my two 6/284's. A one inch group is HUGE to me. I changed to AA2700 in the New Swift re barrel with 50-60g bullets with amazing accuracy and speed, one of the coolest buring powders made. Take a look at the Heat Index chart, look how cool the N165 burns, I would start there. [/QUOTE]
