Shooting heavy metal.
Posted: Mon May 28, 2012 3:33 pm
I went out to CRC for a few hours of practice today. I set up 10 of every target just as the sun was coming up. I wanted to get some trigger time in before the expected mass of club members showed up. Winds were light out of the west at sun up. I had 5 rifles and 250 rds with me. One of the things I wanted to try was hitting extra heavy rams with big bullets. We had talked of doing this at our next match on the 3rd but I got the drop on you guys and got my 7-08 out of the way today
. I c-clamped up to three chickens to two rams that fit the rail with no wobble at all. Short of a ballistic pendulum I figure this ought to tell what 7mm bullet has what it takes to push over a regular weight ram. I was using the Hornady 162 SST and the Hornady 175 Interlock bullets for the test. I used a M700 that shoots these bullets well for the test. All shooting was done from the bench. The 162 was at approx 2550 fps. MV and the 175 at 2500 fps. MV.
Test one was a single chicken and clamp adding 13 lbs. to the ram. Test two was two chickens and clamps adding 26 lbs. to the ram. And finally test three adding three chickens and clamps for adding 39 lbs.to a ram. A 94 lb. super ram. Running this experiment was a real pain in the ass driving back and forth resetting. Always looking back to see if any one had showed up to shoot. I had two hours to my self and completed this crude experiment before a few club members showed up.
Both bullets knocked over the single chicken set up with mid body hits. The 162 SST would only topple the double set up with high back hits. The 175 had no problem tipping a double with center hits. Finally I smacked the triple set up with four different hits with the 162 SST. The super ram would not go over. Next try with a 175 Interlock to the center. It stood it's ground. Another hit to the high back at the horn knocked it over.
I drove down to reset it . Another hit at the top of the butt tipped it again. I had to quit messing with this project as too many members showed up to shoot. I spent the next couple of hours knocking down targets. Good day.
What does all this prove? Not much, but I had fun doing it....or does it?.
