Where did i complain? I said the bullet was too weak for the cartridge/animal. The S MBT in the 338/378 is a target bullet only. Unless you are ok with blowing up smaller animals. With the correct bullet it will be fine.Why do you complain about a 33/3378 blowing up a deer at close range. WOW!!!!
By all means gsteve I apologize and didn't want this to sound negative. I was making lite of your post where you said the SMK with your 338/378 almost blowing up a deer at close range. The power and velocity with that cartridge and then using a match round "SMK" probably is a "terrible" at a close range, but did the job. I know some shooters that use SMKs in a 308 for deer with very good results.. \. I should have used more and different wording.Where did i complain?

I'll play devil's advocate also on this question though. My research indicates the Army uses the 175gr SMK in their standard 7.62 sniper round, so one could easily argue that the bullet has proven to be lethal. The designation of the round is M118LR.
I have used the 142 on antelope. Shot mine at 860, and the bullet did not expand, as one would expect from a 142 smk at that distance. Most consistent bullet I have ever used, but not the greatest in regards to expansion, and clean kills. The antelope did die, but it did go 100+ yards before it did, "both lungs being pierced".Not a big deal in antelope country, but a different story in whitetail country. I would imagine annealing the first 1/8-3/16 of the tips would help in the expansion department.
@dogz have you used the 150 scenar L in your Mashburn yet or do you still use the 150 NBT? interested in results with the scenar.Long and the short, if you said I had to use SMK's the rest of my life I'd load them up and not sweat it one bit!
Between deer/lopes and elk I've seen first hand or used the following, I do not recall ever shooting more than once. Critters generally pretty much bounced at the shot. Lung shots for the most part. On one nice mature bull my buddy shot him @ 110 yards. Intentionally hit both fronts. The bullet went completely thru and the chest cavity was goo..........said volunteer bounced at the report!
One of the elk I took in Wyo was @ 550 yards. I used the 150 SMK out of my Mashburn. At the shot down it went! Also took another bull in Montana at just shy of 500. Again, pretty much boom whack and down it went.
The bullets we've used are as follows and like I said I've not seen anything to scare me off as of yet:
22/250 and Swift=52
6/06=105 or 107
Might of been some more, just can't recall off hand.
