SMK vs. AccuBond

I just had a customer/friend of mine come in our shop and he showed me something interesting. A while back me and BJ were shooting at milk jugs at 940yds, BJ was using his 300 RUM with the 240gr SMK. We recovered one of his bullets from our back stop and found it to measure the following:

Length: .576
diameter at widest point: .715
weight of jacket: 52.8
weight of core: 66.3
weight total: 119.1
% weight retention: 49.58%
The core had seperated from the jacket and only a small piece of lead was recovered.

THe buddy of mine shot a 300WSM with the 180gr AccuBond into a similar backstop but at 300yds. His recovered bullet wieghed as follows:

Length: .604
Diameter at widest point: .752
Weight total: 133.00
% weight retention: 73%
The AccuBond did not lose its core and expanded to a decently larger diameter.

I know this is not the most acurate or precise test ever produced, but I still thought you all might get a kick out of the info

take it easy

Re: SMK vs. AccuBond

What was the MOA accuracy of both loads at those distances?
I keep threatining to try some AB's.

Sound like it would have been a dead animal either way.

Good Post!

Re: SMK vs. AccuBond

I can't speak for the 180 gr but the 240 will shoot well under MOA @ 940 yds. I would guess just over half MOA, but maybe less.

I know we'll get a rise out of POP on this one [img]/ubbthreads/images/graemlins/grin.gif[/img]!!

Re: SMK vs. AccuBond

i guess i'm struggling to see any importance in this comparison.i'm assuming you're shooting into a hard bank,which is not a good test medium, and one is impacted at 3x the distance.for long range,based on the info, it looks like the sierra wins hands down.

Re: SMK vs. AccuBond

I have killed exactly ONE biggame animal with the SMK bullet, so my personal results are (statstically) meaningless. However, based on what I have read on many boards where shooters regularely hunt biggame with the SMK, I have come to some conclusions.

The heavy SMK's, particularely in the 30cal + 33cal are very effective at taking large game at extended ranges when the shot placement is good. Using an accurate bullet like the SMK certainly helps with proper shot placement over the long haul.

In the smaller calibers, the SMK seems to frequently hold up better than other "match" bullets due to its thicker jacket. However, reports on terminal performance of the smaller SMK's seem to vary enough to question their application for hunting biggame. Using "hunting" bullets in these calibers may give shooters a little more comfort.

Now that the industry is producing "hunting bullets" with higher B/C's and improved quality control for better accuracy, I think that many shooters will not be as likely to look at match bullets for longrange hunting.

Just my 2 cents

Re: SMK vs. AccuBond

Not really trying to do a real comparison here, I just felt like reporting some interesting results I had found.

This is in no way a attempt to reopen the debate on SMK's killing ability.

I just thought it was interesting how the SMK hit a dirt bank and substantially less speed and the bullet opened up dramatically and lost its core. The accubond slammed into a dirt bank at 1/3 the distance and substantially faster and preformed perfectally.

Your remark that the SMK won, even though this isnt a contest, is pretty hard to understand. \

I know a dirt bank is not a good test medium, I guess I forgot my ballistic gelatin. Just thought I would remark on what I saw out of the 2 bullets

Re: SMK vs. AccuBond

Not trying to start a war here but I personaly gave up using the SMK's for big game hunting. I have had too many inconsitencies with them. The 168 performed perfect on caribou at 25 yards and 300 yards. Penciled through a dall ram at 763. 190's have penciled through 2 dall rams at both 300 and 600 yards.

Too bad Hornaday doesnt make a 190 AMAX [img]/ubbthreads/images/graemlins/frown.gif[/img]

Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
