30:06 bullet penetration and expansion testing

This will be the second in a series of bullet testing in one gallon water jugs as outlined last week with the .308 Winchester. The .308 was our benchmark test with both a 150 grain deer bullet (CXP2) light framed animals, normally 51 -300 pounds, and the 180 grain Remington round nose Corelokt. The 180 grain Corelokt would be rated as a CXP3 bullet. LINKS for YouTube video testing at bottom of article.

This morning we completed a test for my Savage model 111 bolt action 30:06. A little about the gun: It is a Savage model 111 bolt action with a push button flush mounted detachable magazine. It has a thumb safety, synthetic stock and a blued 22 inch barrel. The only work I have done on this gun was to have an after market trigger installed with a pull weight set at approximately 2 lbs. The gun wears a Mueller 3X9X40 illuminated red dot scope with the dot being 1/8 MOA. The scope has 3.25" of eye relief, has fully multi coated Japanese glass and a German #4 post reticle. The red dot feature has 11 rheostat settings with only about the last 3 having much usefulness, however in low light conditions it makes a shot against a dark target like a black bear, much easier. The field of view for this scope is 39-13 at 100 yards.

We chose to test two different loads in this rifle. First up was the Hornady 150 grain Interbond bullet, and secondly we tried the 180 grain Federal Premium Nosler Accubond load.

A little about the bullets: The Hornady Interbond features a premium polymer tip, a bonded core, with an expansion control ring and a thicker, tougher jacket. This load in both 150 and 165 grain persuasion is very accurate in my 30:06. The 150 grain Interbond would normally be rated a CXP2 bullet because of its weight.

The Federal premium load with the Nosler Accubond bullet also has a polymer tip, a copper alloy jacket bonded to a special lead alloy core and it is a boat tail design. My particular rifle does not normally shoot 180 grain anything well out past 100 yards, however in a baited bear stand with the bait set at 100 yards or less, this would make a great black bear load.

Results on the water jugs were as follows: The 150 grain Interbond blew apart three jugs, penetrated the 4th and was found in the bottom of the 5th jug, which is almost identical to the 150 grain Winchester PP in the previous test with the .308 Win.

The 180 grain Nosler Accubond blew three jugs apart, penetrated the 4th and 5th jug and was found in the bottom of the 6th jug. This is slightly more penetration than the .308 had with the 180 grain Corelokt round nose. The Accubond is rated CXP3 for large frame, heavy animals with tough skin, heavy muscle tissue, and large bones such as elk, moose, zebra, kudu, and brown bear weighing 301 to 1000 pounds. (UPDATE) In our tests so far to date 8/18/09, the 180 grain 30:06 accubond is the winner in the penetration department.

Both bullets showed the classic mushroom and both had adequate penetration.

Next test will be with the Ruger Model 77 Hawkeye in .338 Federal with two bullets. We will be testing the 200 grain Federal Fusion and the Nosler 210 grain partition bullet in this rifle. Stay tuned, as we are discovering these tests together. These are NOT rehearsed and you are seeing them live as they happened. Links for the YouTube videos are at the bottom of this post.
