Hey Rich...do you like the BOSS system on your Abolt?
I love it. And the rifle/BOSS is a very accurate system. One thing tho is never hunt with the recoil reducer BOSS on. Man that thing is loud. The .338 win mag isnt that bad recoil-wise anyways. On a trip to Africa I forgot the "weight" BOSS and had to use the recoil reducer BOSS. Man I had the entire camp hating me after 10 days of hearing that thing go bang.
I love the A-bolt. Like all my rifles I had it bedded and triggered to 3.5 lbs. Ive only shot three bullets thru it. I got lucky and got a bunch of a special run of Swift 217 grn A-frames, and also bought 250 grn A-frames. Ive also shot Sierra match SPBTs in 250 and 300 grns. Not a whole lot of variety but enough to say without question the concept of barrel harmonics is real. I'd also say the BOSS is mostly a device for hand loaders and die hards.
Honestly I dont even know if Browning still makes the BOSS. With that BOSS .338 mag I made the longest shot of my life on an Elk I'd already hit hard but was still up. A Lasered 475 yrds. I never would have taken the shot had I not already hit him. He rolled down a mountain side. My God I wish I had it on video.
Prefer? Hard to say. I have all 3 of my favorite rifles. An A-Bolt, a Rem M-700, and a Win M-70 wooden stock. Both the M-700 and A-Bolt are stainless and all weather. I have 3 M-700s all '06 and under and my A-Bolt is .338. I'd say for .300 mag or bigger I'd go with the A-bolt and for '06 and smaller I'd get a M-700. I just like the feel of the A-Bolt in all weather heavier calibers.
If you want a thumper and weather isnt a consideration nothing beats a Win M-70. I had to have one shipped up from Texas cause it was the closest I could find a lefty in .375 H&H. Boy I got a honey out of a special run of rifles too. I have a 1.5x5 Leo-lll on it along with Ghost rings. Now all I need is the Buffalo.
