280 ai

[Jokostel]

Hey all...
Been trying to get some late work done on a project I have coming up...
I ordered a Nosler M48 Patriot in 280 AI.

I've been running the 280 Rem for years... it's old hat.... I simply wanted a bit of change with the AI...
However, it seems that the mindset on propellant is a bit different.
Currently with my 280 Rem (Model 700 Fluted 24in ) Im running 60 Re22 WLR , max length 3.340.... getting an honest 3050fps with a 140 CT... and about .3moa.

Most folks seem to be running ABLR 150s or the 160 AB or the 168 Bergers....
and sticking with I7828 or Re22...
I want to "try" and stick with 150 grain, as 1: I ordered a few boxes of the ABLRs,
and 2: I have a &@!%#&% ton of 150s in 7mm in general...

Was just wondering everyone's thoughts on the propellants... & if Re23 or Re26 is worth entertaining... supposedly they are the "temp-stable" variants of 22 & 25 respectively.

I have had good luck with H4831SC with the 150 ABLR, and Ramshot Magnum with the 168 ABLR..

I keep seeing this statement made and repeated. According to Alliant, this is an incorrect assessment:

H4831 In the past with other cartridges, I haven't had much luck in the accuracy department... IMR was always the winner..gun)
Never fired up 4831SC though...may indeed have to give it a go.
My only fear is that Patriot is a 24in pipe... a lot of these magic " numbers " are all from 26 in pipes...

As long as I can get close to 3k with good pressures and good accuracy, Im happy...
Would almost prefer Hodgdon as you mentioned... as they are a temp stable powder.

Dunno how much I trust Alliants new propellants.... sometimes the best approach is to go with what you used to know...

Like I said "supposedly" I have 0 idea on them, short of what rumors are out there. Rumors are dangerous.... I have emailed Alliant, but I doubt I'll get much out of them...
Then again, I may actually get an intelligent answer from them... *snicker*

Good info on the url btw... Will read it when I have more time... at work right now... Sigh.

We'll have to crack out that # of rl26 I have in the 7rum's and 7stw on Saturday Jokostel... rl23 may well be the better choice in your 280ai though.

My 280AI shoots the 150's very well. Most accurate so far has been with H-4831

I shoot H4831SC in my Cooper 280AI with 168 Bergers. Never tried any other powders as this was very accurate.
