I reckon the Barnes data is more generous.
The thing is that the data I've seen is for their non-tipped rounds, with are a good deal shorter than the tipped ones, so you may have a lot less room. Also, different cases have different capacities.
I'm running with 51.0 grains of AA2460 with the Barnes 130 TSX seated to 2.800" (max load), it's supposed to be less than 100% full, but that's not what I've found!
I've also been testing with AA2520 and the Barnes 150 Tipped TSX, with 47.0 grains and 48.0 grains, the powder is compressed, though the 150 is a lot longer. I won't be trying any more than 48.0 grains because that's as much powder compression as I'd like! Besides which it's easily a hot enough load. (I'm going to try Viht N140 next as the accuracy wasn't there, but it's unknown territory with Viht)
I would just say: be careful, work up slowly and if you can't stuff more powder in, stop ! A different brand of case may give more volume, or seat bullets out longer if you've got room in your chamber / magazine.

Try a six or eight inch drop tube mate, it'll help the powder pack down better and give you more room in the neck for the bullet.

I just had a look on Hodgdon's website and could not find an exact load for your particular bullet, what I found was 130 SPR HP using varget. For this the starting load was 47 grains which gave 2975 fps @ 42900 CUP, the maximum was 50C which gave 3130 fps @ 50400CUP.
Always use the powder manufacturers data not the bullet manufacturers. It is all on the web you can even download manuals in some cases.
