280AI powders

[newmexkid]

Still working out a load with my new 280 AI. Of the following powders, using a 140gr. Accubond, H4831SC-IMR4831-RL22-23-26 which would generate the most velocity in a 26" barrel?

I've used both H4831SC and RL26. RL26 is consistently 100fps faster. I'm getting 3177 shooting a 143 gr Hammer bullet and 3061 with a 160 gr Accubond. These velocities are in a 24" barrel.

I get 3200 FPS using h4831sc using a 140 accubond and 3060 using reloder 26 shooting a 160 accubond

I'm using H100V with 143 Hammers getting 3100. Never tried pushing it any faster as I was more then happy how it was performing and short on time.

Shooting a Barnes 145 LRX, over RE23 and getting 3100 easily. 26 inch Proof. That's where my accuracy node is. No pressure signs.

RL26 will be fastest

 

[L.Sherm]

I had the exact same velocity between 23 and 26 but 23 was more accurate.

168 accu-bond long range with RE 19 2960 into one ragged hole with 24 in barrel

H100V with 140gr TTSX.

L. Sherm reminded me of RE-23 to replace my load for RE-26. I got two pounds and first load was .5 MOA, cool! Then I saw 26 back in stock and have 6# on the way. LOL Now I have choices to play with...

With a 26" barrel that may play a role with so much burn time compared to my 22"? Enjoy!

Haven't had a chance to finish the load development, but at 200 yards, it's looking promising. 145 Barnes LRX.

Admittedly I have no experience with the Alliant powders, but both 4831 powders have given me excellent accuracy in 28 calibers of that general case capacity and mid weight bullets. May not be as fast, but stable, and accurate.

With a 24 inch barrel, I got better results in accuracy with the H4831sc at 3070. I did get better velocity with the r26 by about 80 feet per sec. but the accuracy wasn't as good.
