Range day

[kevshell]

Today I went and spent a few hours at the range making sure our elk rifles are on. In addition to those I brought a few other toys as well. Plus today was the first day I really spent some time with the Garmin chronograph. Definitely like this way better than the old sky screen chronographs that I've used. At one point I did think something was wrong with it but it's because I assumed the velocity was a little lower for the 45-70 rifle. It just wasn't registering. Seems to me it would have given me a error message or something But it just appears though it wasn't registering anything. Once I got that figured out everything moved along smoothly.

This was the Marlin Ruger trapper 4570. It's quite accurate with the Hornady 350 grain jacketed flat points. But the 350 grain lead flat points were just a pleasure to shoot. The jacketed flat points are really intended to be more for back up in bear country.

I brought a Big Horn Armory 475 Linebaugh rifle along with two handguns. I had one load which was a 410 grain cast bullet over 14 grains of HS6. The rifle average 1,215 ft per second and the handguns averaged 1070 ft per second with the same load. This is a pleasure to shoot in the rifle but definitely smacks with authority once the bullet gets there.

This is my Cooper 300 Win Mag. When I first shot this rifle and got it dialed in I was in North Carolina. The skyscreen chronograph in North Carolina gave me an average speed of about 2950. This Garmin in Montana is telling me an average of 3,042 fps. I'm assuming this has more to do with the altitude being 4,000 ft higher as opposed to a difference in the chronograph. The group below was at 200 yd before I made a final adjustment.

This is my wife's Nosler 28 Nosler rifle. I was happy to finally get this one clocked with a chronograph. The speed this thing turns out is pretty amazing. Now I need to get the CDS dial ordered from Leupold. This is a flat shooting rifle that shoots very well. This group is the last 200 yd group I shot.

That 45-70 load is moving pretty good for a Trapper and 350gr. bullet. The velocity difference on the 300 could easily be environmental conditions, but it is more than I would think.

Trapr…….PS I finally purchased myself a Garmin as well.

It was spicier than what I wanted anyway. I'll probably throttle it back to 1500-1600.

INFORMATION BEATS THINK, ASSUME, GUESS, ESTIMATE, etc.

I learned a bunch when I finally got a chronograph. I wouldn't be without one developing loads now. Since velocity equals pressure, it's much easier when you get a fresh lot of powder to just load back to the same velocity than the old guessing game of loading back to the sights.
