Re: Barnes Triple X--in the field perfomance

bigmax - try the TX .224's on paper. You may need to run them .030" or so off the lands. I started with .040" and found under 3/4" accuracy at .030" using the Blue coated ones as well as plain vanila X's. Closer might raise pressure unduly. The TX is supposed to allow closer seating, but even int he 7mm Mauser, .050" off the lands gave sub MOA acuracy. The big cased .22s can pump up pressure pretty quickly as I found with the .22 Swift IMP.
I'd go for the 53gr. bullet (or whatever the TS is) and work on a descent load. It will work if you do.
I have attended several seminars with Barnes while at SCI--the info they have always stated is to start at .050 off the lands and work from there..
for myself on my .280, I used 120 Tipped triple shocks--they are .040 off and shoot under 3/4"...wiht my .25 caliber it is actually .030 off...and shoots about the same size groups...
Plan to use some in my 220 Swift as well...
As BigMax stated, I too am a big fax of the A-Frame and will continue to use them..however one advantage I think Barnes may offer is that you can go to a bit lighter bullet for caliber --so a bit flatter trajetory which can be desirable here in the West where 200, 300 yard shots and beyond are not that uncommon..Which is what I did with the .280 this year..went from the 140 gr bullet at 3040 fps to a 120 at 3260fps...not that much difference ...probably more psychological...but it worked very well...and while I know that in some cases the heavier bullet may retain more velocity at longer ranges, it was not the case as I ran tests to 500 yards...
