.375 Ruger on the Chronograph
OK, I recently read something about the Hornady claims of velocities being "padded" and the acual measured velocities not matching that in the real world. That I wanted to see for myself and wanted another excuse to shoot my new rifle. So I borrowed my neighbors chronograph and went to the field. The rifle I have is a new Ruger Hawkeye African with a Nikon Buckmaster 3-9X40 scope and the ammunition I used for the test was Hornady 300gr. DGS. My buddy took his Winchester Model 70 chambered in 7mm Mag. and fired Monarch brass cased 150 gr. ammunition, it was on sale, which we also put through the chronograph as a "control" for the test. Now I know that ballistic information printed in ammunition catalogs are fired through a 24" test barrel, etc. but I wanted to see how the ammunition did through my rifle and how far off it really is. The chronograph was approximately 10ft from the muzzel and here is my results by shot.
Shot 1 = 2658
Shot 2 = 2611
shot 3 = 2570
shot 4 = 2572
Hornady advertises at the muzzle to be 2660.
The 7mm hung around 2820fps. with the Monarch ammo, which I don't have their data for, but Hornady says theirs does 3035fps. in the standard cartridge with a 154gr. bullet, so I believ that the chronograph was working accurately enough for my non-scientific test. The weather was in the 50's and windy. Both rifles were very accurate and fired well although the modle 70 had some feed issues with the Monarch ammo. So my conclusion is that Hornady didn't really "pad" anything and you should expect their ammunition to perform very close to advertised. This was just a fun test to perform, and gave me a target velocity for my handloads once I get the dies made. Anyway, hope you all find this as interesting as I did!:beer:
