I wanted to use an extreme powder for the temp sensitive but i just am not getting the velocity with them as i am with the hybrid 100v. Am i doing something wrong here? any tips or suggestions would be good. I know i could use a magnum primer but i have 3k benchrest primers so i really dont want to buy any more.
Having two 280AI's in the family - both have 25" Kreiger barrels and both use 168 VLD's, I would be very surprised if you can get up to 3000 fps with any Hogdon powders unless you really push the envelope at max. My son has reached 3000 but only with RL22 and we have pretty much tried everything.
Couple of questions for you:
- Are you 100% confident on your chrony readings?
- At what distance in front of the muzzle are you setting your chrony, and are you backing that distance out on a ballistic calculator to get closer to your true muzzle velocity?
- What elevation are you?
I've settled in on H4831sc at 2840 fps with the 168 VLD and after 20 some deer, elk, antelope, bear, and a sheep I just don't feel another 160 fps would have killed anything any better.
My whole key on this velocity thing has changed after many years of chasing more velocity all the time - which load shoots the best? And I don't mean at 100 yds off a bench. After you've went through way too many barrels it'll finally hit you.
