280 AI Load Data Please

Having a 280 AI built by score high. Blueprinted 700, Bartlein 26" M24 5r 1:9, Manner MCS T4A. Berger doesn't have 280 AI data yet and I was hoping I could get some people's favorite loads. I plan on using: CCI #200 primers, H4831SC, and 168gr Berger VLD's, so if you have a favorite 280 AI load or have some recommendations to make, please share!

Re: 280 AI Load Data Please

Those gun specs will be pretty close to mine, when it's all said & done.

I have been researching Bartlein barrels, and Brux, and about the only blanks I can find are Douglas Air-Gauged #7 contour, and a Bartlein M24 5R blank.

Since the Bartlein is a 5R rifling and a 1:9, I will most likely go with that blank.

I am interested to see the load data as well.

Except for mine I will be using IMR 7828 SSC, and Fed 210 primers, behind the Berger 168 VLDs.

I am running 57.0 grains of H4831SC behind Berger 168's. This is a near-max load from data I have seen, so work up with care. I have no pressure signs and could likely go higher but accuracy is great so I'm not messing with it.

I could never get the speed I wanted with the accuracty with H4831sc. I ended up getting a good load with H 1000. I shoot the 162 A-max with 63.5 of H 1000 in my 280 ACK..I have Douglas barrel with 1-9 twist. Remember start low and work up.

Here are some groups with 160 NABs. The Bergers shoot just as good...

Re: 280 AI Load Data Please

That's good that H1000 seems to be working pretty well, I have a good bit of it sitting around for my magnums...

But still, I would love to find a load for IMR 7828 SSC, if anyone has a good one for the 160 NAB's and 168 Berger VLD's.
