[M.T. Pockets]

I owned a Browning A-Bolt with a Boss and they referred to the "Sweet Spot" in the owners manual.

They had suggested settings for the Boss for different calibers and bullet weight combinations, but they also said that you should experiment to see how your rifle responds.

I've see some aftermarket adjustible weight devices to try to do the same thing.

I'm sure that these settings are helpful if you're serious about getting the best possible performance from your rifle. Personally, I think a good handloader could reach the same results. I couldn't say that I took full advantage of the Boss to improve my accuracy that I could notice. I shoot factory ammo without a Boss now, and I'm happy with the results I get, although my rifle absolutely hates some loads and will shoot 1" groups with others.
