IMR 4955

[Brian in Montana]

Ever use this stuff? .270? .280AI?

I've used it just for a few rounds in a 6.5-06, but no remembrance of results. Supposed to be the cat's meow for a .25-06. Does have a copper fouling reducer added. Somewhat faster than IMR7977.
Quickload shows 55.7 grains for a Sierra 130 grain TGK in a 6.5-06. I'd start at 53 if twas me. 54.4 grains in a .25-06 and a Hornady 117 InterLock #2552

The Endurons don't seem to be near the top of the list as far as velocity producing powders go. Unfortunately I don't have access to my QuickLoad source right now.

Just ordered some 4955 to do some tests with my 7mm Rem Mag and and 300 WBY. I’ll be shooting light-for-caliber bullets—130 grain in the 7Mag and 151 grain in the 300 (Absolute Hammers) and am thinking 4955’s burn rate should be good for both. Burn rate is pretty similar to RL22.

I’ll post results when I get them, but it’ll likely be a while. Focused on other loads right now.

Works well in 30-06 and 270. Slightly slower than H4350 in my experience.

I've got 2 great 30-06 loads worked up with it. Accurate, fast, low ES.

It's slower than H4350 for sure. It's even a couple notches slower than H4831. Should be a good option for 280AI and 270Win with heavier projectiles.

I just bought some to try in my 25-06 and maybe the 280 Rem if I don’t rebarrel it to a 280 AI before the summer. We shall see.

Might be a good choice with the hammer bullets. Checked my notes and with a 6.5-06 and Barnes 127 LRX 53.0 grains of 4955 was giving pressure signs where 59+ grains of 7977 wasn't.

Just got 15 pack of 131 Hammers in the mail this week. I'm interested to see where you get with this. I'm shooting a 26" M70. QL is still pointing me to RL17 or H414/w760

It’ll likely be on the slower end for the 131s in the 7 Mag. I bought it more with the 300 WBY in mind. Probably won’t be until this summer before I start messing with it, but I’ll be sure and post about it in the Absolute Hammer load data thread @JLS started.
