Bought new rifle, Old Sako AV in 9.3 X 300 WM - 2967 FPS with 286 NPs

Congrats on a fine bear with an awesome rifle. I envy everything about your photos. Thanks for sharing. I can hardly wait to get out for Ontario bears with my son in August.
 
The smoked bear ribs we just put in the freezer, along with some smoked lake trout from the trip Phil and Rick and I made last Thursday, are about as fine as it gets.

Doug's 9.3 Yukon has done the deed. Now, he just needs to get some Matrix bonded core bullets for it. That will pretty much ice the cake!

Smoking is bad for you. :)

I know, I know.......I've been working on giving it up but have yet to succeed.

Hamhock.....Went out for a drive with the 9.3 Super just to do some terminal ballistics testing on a blackie. Turned one down about an hour out of town and then missed one a couple hours later (yes it does happen and I admit it when it does)steep uphill shot at a medium blackie and it seemed to duck as I pulled the trigger and I knew I was high already but shot over for a clean miss. We went up and found her tracks and followed then for about 50 mtrs with no blood. Heading back home when #1 son said he saw ears, stopped the truck and walked back, made a short stalk until we could see the ears again then waited at about 50 mtrs. He was laying behind a swell and eating grass, facing straight on and down hill from me. Finally he noticed us and lifted his head a little, I tucked the crosshair just under what I perceived to be his chin and touched her off. The bullet strike made a loud meaty smack and he disappeared behind the knoll, no worries I knew the hold was good and he was going no where. Told the kid to run down and see how big he was while I waited at the top, he was there dead and the rest is told by the photos.
Terminal performance....

270 gn Speer semi spitzer hot core
Muzzle velocity of 3030 fps (this was the load I had worked up to last fall when it stalled with RL 17)
Accuracy unknown but stopped in an old gravel pit just out of town on the way out and I hit an old oil filter 2 for 2 at about 100 mtrs so I decided it was definately shooting m.o.b. (minute of bear) and we carried on.
Bullet struck the bear dead centre of the lower lip, removing the meat and hide but not breaking or even furrowing the lower jaw bone. It broke into pieces at this point and entered the upper chest/lower neck in 6 separate pieces, some of the larger pieces carried through to destroy the spine ahead of the shoulders. Maximum total penetration of less than 12" largest piece of bullet recovered less than 2 grns and no pieces exited. No damage below neck at all or to the heart lung region.
Conclusion

Performance was as expected with a c+c bullet impacting near 3000 fps.


RESULTS

Dead bear, bigger than anticipated, will make nice rug and a very respectable skull.

BUM where are you? I went out and did this at your very specific request.

And for those of you who care, I made a couple of calls and was able to give the meat to Medvedqc (Phil) who will use it, which I don't with bear.

Now back to load development, considering the complete and utter failure of the 270 Speer I have decided to cease load development with it and have just spoken with Marshall @ Matrix bullets and ordered some of his 270 gn spitzer rebated boattail bullets which are a bonded/welded core. I like the 270 gn weight for the 9.3 and have never been much of a heavy for caliber advocate. I do have a rack of test loads for the 286 gn Part and RL 19 which I will try to get to the range and fire and chrono shortly. And of coarse I will share the results here.
Thanks to all who are following and posting, it keeps me motivated.

Smoking gun, smoking hunter, smoked bear ribs, I think I see a pattern here........................;)

Ted I hear your Atlin adventure was not without its hiccups.........

Interesting quote from that thread, by John Barsnes



One of the problems with the old "pressure sign" of sticky bolt lift is that it used to be much more common in older rifles, with locking-lug surfaces and bolt faces that were often (or even usually) not particualrly square. When the case expanded a little too much, it was noticeably to open the bolt, due to those out-of-square surfaces, not to mention a case head that might have been pushed out of square. This was even true of the vaunted pre-'64 Model 70, because the action was heat-treated AFTER machining, which slightly warped the action.

These days even most factory rifles are more precisely made, and today's custom rifles are very square and smooth. Often sticky bolt-lift doesn't occur until pressures are way over 65,000 psi, or even 70,000.

One of the examples I have used several times before is the 7mm STW. When Layne Simpson developed it as a wildcat, he depended strictly on traditional pressure signs, and reported muzzle velocities with 140-grain bullets of up to 3600 fps at "safe" pressures.

When Remington decided to make it a factory round, they pressure-tested a bunch of those handloads, and found all were AT LEAST in the 70,000 psi range, and some well over. Which is why no 7mm STW factory load gets more than 3400 fps with a 140-grain bullet.


I mentioned something similar earlier in this thread, although Barsnes obviously has much more access to ballistics labs than I do. :)
 
Be that as it may Gatehouse, I am not experiencing sticky bolt lift, nor loose primers, nor ejector marks. No one is asking you to load as I do, but I'm using the same protocols I've used for 40 years of working up loads and it has never caused me any problems yet. May I suggest you oppose this thread solely because this cartridge makes your pet look pretty docile.:p;)

Different Phil than on the above-mentioned lake trout fishing trip, but this Phil really knows how to cook bear meat! The best bourginon I have ever eaten.

Now back to load development, considering the complete and utter failure of the 270 Speer I have decided to cease load development with it and have just spoken with Marshall @ Matrix bullets and ordered some of his 270 gn spitzer rebated boattail bullets which are a bonded/welded core.

You will be very pleased with both the accuracy and the expansion.

I don't "oppose" this thread, just relaying some information from someone with lots of access to ballistics labs that have pressure testing equipment. Here is the most important part of his quote:

My approach to loading differs from yours in that you choose to push the envelope for no practical reason, whereas if I want higher velocity, I just use a bigger case.

I'm here, I'm here. It's been a busy few days since I got home. Who knew that being home without the wife and kids would actually make me busier?

Nice bear Douglas. Not surprised the HotCor behaved the way it did...it's a pretty wild ride for a soft bullet like that. That case might be the one to make the best use of teh 286 TSX which is, in my opinion, too long to be effectively used in the x62. And a 250 TSX would really howl out of that rifle.
 
I know, I know.......I've been working on giving it up but have yet to succeed.

A couple of friends have had good luck with those electric cigarettes. Then again you may be related to George Burns and you can smoke to your heart's content and not have to worry about it. ;)
