IMR4451
I loaded 200 cartridges in 6.5 Creedmoor using Lapua brass with small primers and 135 grain A-tip bullets. I used these at a 1000 yard training class and the powder performed excellently. The first morning was below freezing and the second day was 45 degrees. No change in trajectory from one day to the next, and I was getting 2775 fps with a 42.8 grain load which was mildly compressed in my once fired brass. I noticed excellent consistency with this powder and consider it as good as H4350.

Powder
This powder works great, vary reliable and consistent. This powder performs like a higher end powder. This will be my new go to powder for 6.5 creedmoor.

Most Accurate Powder with 123 -grain bullets in .260 Rem
Tried several powders while developing loads for a Remington 700 5R Milspec in .260 Remington. IMR-4451 gave the best accuracy, even over the vaunted H-4350, using 123-grain bullets. Happy with results!
