Well I was able to get away for a quick range session. I loaded up 18 150gr ABLR's with 7828SSC. I shot over a Shooting Beta Master set up at 12 feet from the muzzle.
Scotty was kind enough to take my case capacity measurements and send me some Quickload data to start with. His numbers came out that 59.5 was the maximum.
I loaded 3 rounds each at 56.5, 57.5 and 58.5 with Fed 210 primers and a depth of 3.375. My lands are at 3.390 and the mag box is right at 3.380 in my Winchester M70 Classic Stainless. I also loaded identical loads with Fed 215 magnum primers.
56.5 is the sweet spot. 57.5 the groups opened up, and 58.5 the bolt was sticky and the primers were severly cratered.
Here are the results. I fired one "fouler" of 130 BT silvertips at the bottom of the target. Shots 2, 3, and 4 are the three shot string.
56.5 grains with Fed 210: 3007 FPS avg. Group size .493 :grin:
3014 FPS
2996 FPS
3013 FPS
56.5 grains with Fed 215 Mag: 3038 FPS avg. Group size 1.623
I called the third shot pulled and boy was I right.....

Using the magnum primers were very interesting. If I wouldn't have gacked the third shot at 56.5, I believe I would have bested the regular 210 primer group. Also the FPS were very consistant using the mag primers.
I am going to make up some more loads at 56.5 with both primers and go back tomorrow or Friday and reverify my numbers from today are correct.
Man was it fun and to see the Old Man break 3000 FPS with 150gr pills was pretty cool. I think these new ABLR's are gonna have quite a few people dusting off the "old .270" and taking her out again.
