BOSS & Temperatures (Was Re:Best Varmint Rifle)

I’ve ofter wondered if the BOSS would serve a shooter well in temperature changes. For instance: You make up a good load for your gun. But you do it in 65 degree weather.Then you go hunting in 10 degree weather. Take a few shots and tune the BOSS in to make up for temperature change for the load. Has anyone had any experience with this? Anybody tried this with their BOSS?

It is an advantage, even if you reload. How often are your best reloads at the maximum? That is what I use for hunting. > I’ve ofter wondered if the BOSS would serve a shooter well in temperature > changes. For instance: You make up a good load for your gun.

BOSS? I spent a year tuning my Browning BAR with BOSS so I got the full range of temperatures from the mid-20’s to just about 100 degrees. I did not notice much of a change due to temperature. There was continuous improvement in my groups from the early spring last year through the summer into the fall and starting again this spring. This was due to BOSS adjustments and handloading, not the temperature. When I first got it, I was getting 3 to 4 inches at 200 yards with factory ammo. Not good enough. With practice, adjustment and handloads, it is now always well under 2 inches and occasionally under 1 inch at 200 yards. BTW, the last load I posted was the was the second one I worked up. The first one duplicated Remington factory loads, with a Remington 150gr PSP flat based soft point and Remington cases. I was averaging about 2-1/2" groups with an occasional 1-3/4". I thought it was good enough, but then I read a magazine article that tested a LOT of 30-06 loads. One bullet (the Hornady 150gr BTSP) had much smaller groups than the others. I decided to duplicate it (after dropping the powder 10% and working back up again) and found that it immediately dropped the group sizes by about an inch. I rechecked the BOSS setting and found that it did not even have to be changed. I have taken it to the range enough to know that it is consistent. From my experience with it, I do not think the BOSS is as sensitive as some people believe. The best groups stay at about the same setting with a given bullet weight. Change the weight, and the BOSS setting changes a lot. I don’t think that temperature can even be noticed. Also, the "sweet spot" is wider at 100 yards than at 200 yards. At 100 yards, 3 marks give about the same group sizes. At 200 yards, there is only one place that gives the smallest group. But that group size is spectacular.

In the testing of the Accumajic Accurizer i personally have noticed some changes but this is usually only just a simple click away, Of course the type of powder that you use could be more suceptable to temp changes Just ask the Benchrest Shooters Good Shooting Brian Nasset "I’f that hunting rifle doesn’t shoot under 1/2moa or the varmit rifle under 1/4 moa Then the Accumajic Accurizer may be for you For more info please see the web page http://www.inventorworld.com/ami/acculink.htm Visit the rec.hunting and rec.hunting.dogs FAQ Home Page at: http://sportsmansweb.com/hunting/ To leave the Hunting listserv list, send a message with SIGNOFF HUNTING
