I recently recovered a 150gr partition from the neck of a moose that we were butchering.The bullet had barely penetrated the neck vertebrae which was surprising for a partition. .


It is common not to get full penetration on the neck of moose deer elk even with larger calibers. The heavy interlocking bone is tough on bullets. I think you could shoot the neck/spine bone 10 times and get 10 different results because of the odd angles that the bone has.
 
My moose was shot at 170ish yards with ancient Imperial 160gr RN ammo. went right through the spine and was found under the hide on the off side. bullet weighed 99grs after recovery and cleaning.
 
the 270 will work but i would prefer a .308 cal 180 gr bullet or bigger they got alot of big bones on them and you need a cal that will punch trough the bone.
talk to ya all later

I think sectional density is over-rated. Far more important is momentum.
A 140gr. 6.5 mm bullet at 2700 fps has a momentum value of 54.0 lb-ft/sec
A 160gr. 7mm bullet at 2700 fps has a momentum value of 61.7 lb-ft/sec

These two bullets have almost identical sectional densities; .287 for the 6.5 and .283 for the 7mm.

OK, so then it must be the difference in the energy you say. Well, no. If you lower the velocity of the 7mm bullet so that the energy is the same, 2525fps, it still has a higher momentum value: 57.7 lb-ft/sec

The point is this: the 6.5x55 has really good killing power, especially with the 160gr bullet. Most people attribute that to high sectional density. If we say that the bullet is launched at 2500fps, then the momentum is 57.14. A .270 launching a 150gr bullet at 2800fps has a momentum of 60.0. This shows that, all thing being equal (which they never are) the .270 should penetrate as good or likely better than the 6.5 even though the sectional density is much lower.

In other words, it should kill the moose just as dead!

This is just my idea and I don't know too much about ballistics. But I started thinking about it after I talked to my friend about using heavy arrows for bow hunting. We started doing some calculations and the results are interesting. Based on these ideas I used heavy shafts and up to 160gr. broadheads with my crossbow. Penetration was very impressive. I once spined a ~150lb boar from about 40 yards. About 10" of the bolt was sticking out past the spine. May not sound like much, but that is a lot of resistance.
 
500 grains...must be making up for something else

if they made a Porsche for "husky gentleman" I'm sure they'd sell at least one up in Burns :mrgreen: :wink:
 
yes Remingtons are trash, must be all the plastic parts on them :)

are you going to kidnap me... :shock: :eek: :| :mrgreen:

Ive seen it done. I know someone who just got a grizzly with a .270

One of the largest grizzlies on record was killed by a native lady that used a .22 with shorts nonetheless.However that does not mean that the .22 is a suitable cartridge for grizzly hunting.
