Home Forums Hunting & Shooting Elk Hunting 284 VS 308

Mark, shouldn't bee too hard to run a 155 Scenar at around 3,280 +/- with RL17.

I also agree about "reaction to the hit" with the bigger rounds... have noticed the same. It does give a guy some comfort.

One of these years I'll get another 270 and kill a few elk with it and see if I can't recover a bullet!

I'm getting 3,330 with RL17 and the 155 Scenar. Best accuracy too and that's not difficult with that bullet.




I agree with that and that's why I like 30 mags for elk.

Just remembered one bullet we found (out of the .270), on a bull we shot down by Gardiner. 5 point and the 140 Horn was found looking nice and comfy about to exit.

3280 sounds stout for my gun but maybe, how much 17 you thinking to get it there? I've been shooting 67 and it seems to me it clocked a bit over 3100. I shot 69 the other day but didn't clock it, I don't think and me thinking is always a scarry thing but I don't think it'll go much over 3200. But, I've been wrong many many times b4...grin

I was posting while you had Bob, how much 17 are you running to get to 3300? And how long a tube, mine's 23".

Thx, and have an awesome day there my friend.

Mark,

Looking at my notes again.

24" barrel

Running 69.0 grains
Norma brass
Win primer

That 69.0 is a drop of .5 to get down
to 3,300 with a very low ES of 10 fps.

With the 4 30 shorts I've run all loved Norma brass for accuracy.
Nosler Pro Shop had a bunch for sale cheap and I snapped them up.

edited to add...
Norma brass may be a little thicker and run a little higher pressure.
Safe load in my rifle though.

I've recovered quite a few 270 bullets from animals-Ones I can think of right off are some 150 Interlocks, cow elk, 425 yards, 150 Ballistic Tip, small bear, 60 yards, quite a few 140 Ballistic tips from deer, one a very large buck, shoulder shot at 200 yards or so,
Had 3 Ballistic tips that stopped in a 6 point elk, before range finder days, but I was getting over 4 feet of drop on my shots. Usually, the ones I weighed weighed about 60% of original weight. I credited the Ballistic Tips for stopping a couple of animals that were hit too far back, never had a legitimate gripe with them. Certainly seemed to kill better than a 35 Whelen I had for a while.
Until I came here, I had no idea they were such a wretched failure as a big game bullet. But, then, I used to shoot gophers with that 270, and when I flopped down and put the tripod legs down, it wasn't too big a trick to slip that Ballistic Tip in tight behind the shoulder, with very predictable results. A friend has used one of my 270s for the last several years with 140 BTs with similar results, including a gorgeous mule deer in Wy that scored 180 or so.

SU35 and Dober the data with RL17 and 155's...May I conclude you are discussing the 300 WSM? Reading Dober's post I wondered if he was thinking of the 30/06 ?

Rin, both are talking 300 WSM... I think Mark's pretty conservative with his load and I have no doubt there's more room... OTOH, it shoots great and 3,100 is penty fast for anything!

I have sorta noticed this,too.....is this like,when you come down outta recoil....and they ain't there?

Beautiful day here, 28 and sunny gonna try to get some more shorty mags loaded and ramble out to run them over the clock. Will check in later if I get it done.

[/b]thats[b]. Been my experience with the 340 B

Two thoughts:

The discussion of 7mm's perhaps penetrating better than 30's, depends on bullet construction and impact velocity and impact material, more than caliber. A soft 160gr. 7mm hitting at the same speed as a harder/stiffer 180gr. .308, will penetrate less than the .308, if all else is equal, which it never is......

Second, a 160gr. .284 cal. hitting at 2900 fps cannot be as "powerful" (however you measure that)as a 180gr. .308 cal. hitting at 2900 fps. This simply has to be true. Can you see the difference "in the field" on elk? Maybe if you shot hundreds of elk with each caliber, you might be able to be definitive, in some way.

I have not shot all that many elk with various 7's, but I have with .308's and 338's and I am certain I see a definitive difference in how the 338's hammer elk versus the various 30's I've used...........but this is an OVER-ALL statement--so the same theory ought to apply to some degree, to the 7mm versus 308.

THAT spells big time trouble for me... One of those might make me give up the 7 WSM...

A sample of one
RL 17 with 155 Scenars in a factory 24" Rem 300 WSM
65 2912
65.5 2991
66 3088
66.5 3089
67 3152
67.5 3162
68 3184
68.5 3233
69 3286

This is pretty spot on for my Sako A7 300 wsm using win brass win primers and a coal of 2.880.

FYI--I just started a new thread on the 300 WSM/R17 combo in the reloading section so we didn't take away from this thread too much. Not that that ever happens..grin

Dober

In regard to the original quesion of 7mm bullets vs. 30 caliber,I have hammered a bunch of hogs with both.

I think the 30 caliber tends to make bigger wound channels.

I know that I used my 300 WSM this year to take deer,hogs,a mountain goat and an elk.

They were all pretty dramatic kills.

I did lose a really big hog this year that I had hit pretty hard with my 280. I don't think I've ever lost one with a 308,30-06,or 300 mag.

I know that a sample of one doesn't prove anything,but a 180 grain Acuubond or Partition is hard to beat and so far nothing has walked away from either.

Doc-u loading for your 300 shorty or burning factory?

Thx
Dober

I have dies for a bunch of stuff,but not for the WSMs yet.

I have used factory 180 failsafes,180 power points,180 Accubonds,and 150 Balistic Tips.

So far nothing has stopped any of these bullets,I think that includes five bull elk and dozens of deer and hogs.

After all, you are loading Partitions....

.284 or .308, shoot whichever you like and whichever you find most interesting. I've heard it said before that bullets matter most and the .284 cal 160gr Partition is rediculous (in a good way)...
