10mm Hunting / 10mm Kills Brown Bear in Homer, Alaska

For those who ask whether the 10mm is sufficient for bear defense. It was about a week ago...

Hiker injured in Kachemak Bay State Park bear attack

A Homer man shot and killed a charging sow brown bear at Humpy Creek last Friday. Kim Woodman, 57, shot the bear five times with a 10mm handgun before the bear fell about 6 feet from him. While backing away from the sow, Woodman fell and accidentally shot himself in the left foot.

Woodman was able to get to his skiff and return to Homer, where he checked into the South Peninsula Hospital emergency room. Woodman had no injuries from the bear, said Jack Blackwell, area superintendent of Alaska State Parks, Kenai-Prince William Sound region.

Blackwell said Woodman surprised a brown bear with two cubs while hiking about 4 p.m. July 29 off the trail along the southwest fork of Humpy Creek in Kachemak Bay State Park. The bears were probably feeding on pink salmon in the creek. Woodman filled out a defense of life and property report, and Park Ranger Jason Okuly and Alaska Department of Fish and Game biologist Jason Herreman went to the scene and found the dead sow bear. They reported the sow had two gunshot wounds, one below the right eye and one in the chest.

They recovered the skull and paws to prevent trophy looting. The carcass was about 6 feet from where Woodman tripped.

“It was fairly close,” Blackwell said.

Fish and Game Kenai Area biologist Jeff Selinger said the sow had been lactating, but it’s unknown if the sow had cubs of the year or older cubs. Older cubs would have a good chance of surviving, but younger cubs would not. Selinger said Fish and Game won’t make an effort to look for the cubs unless they hear reports of the cubs hanging out in the area. Biologists would have to be certain the cubs were orphaned and not another sow’s cubs.

“We care about the animals. The thing we want to avoid is making a bad situation worse,” Selinger said.

Selinger said this is the first defense of life bear shooting he knows of since 2002, when he began working for Fish and Game on the Kenai Peninsula. Black bears are more common in Kachemak Bay State Park.

People who shoot bears in self defense are normally required to salvage the hide and skull, but because Woodman was injured, he did not have to do so, Selinger said.

This is not Woodman’s first defense of life bear shooting. In September 1992 while moose hunting near Ohlson Mountain, he shot a brown bear Woodman said was stalking him. According to an Oct. 1, 1992, Homer News article, Woodman injured the bear with a rifle shot at close range and then killed it when the bullet failed to pierce the bear’s skull and it got up

Gunsmithing / STI Perfect 10 and Dan Wesson Bruin-Spring Weight Irony
« on: August 03, 2016, 08:40:13 PM »
I bought an STI  Perfect 10 several months ago and contacted STI to find out the spring weights and how often they should be replaced. An STI rep emailed me stating the Perfect 10 has an 18 lb recoil spring and a 22 lb mainspring. Last Saturday, I purchased a Dan Wesson Bruin online and emailed CZ/Dan Wesson to ask the same questions. The CZ/Dan Wesson rep communicated the Bruin uses a 22 lb recoil spring and an 18 lb mainspring. The complete opposite of the STI.

I'm new to the 1911 platform and I suppose there is a window of spring weights which would work just fine in these pistols depending on the ammo being used but it just surprised me to see such a difference in spring weights between them.

I bought several hundred 200 grain WFNGC Beartooth and DoubleTap bullets to handload for woods carry and hunting. I've only done a little bit of load development with those bullets thus far and will have to wait til spring for warmer weather to complete it.

In the meantime, I thought I would share some info I have gathered on these two bullets. Obviously, one will be more accurate than the other in your pistol but the consistency in the weight of these bullets is interesting.

I randomly selected 25 bullets from each 100 round package and weighed them on my RCBS digital scale. I have no idea how much bullet lube weighs but since no two bullets will have exactly the same amount of bullet lube I would expect this to play somewhat of a role in the overall weights.

Here's what I found:

Beartooth 200 grain WFNGC weights of the 25 bullets varied from 199.0-201.4 grains. That's a variation of 2.4 grains.

DoubleTap 200 grain WFNGC weights of the 25 bullets varied from 193.4-200.7 grains. That's a variation of 7.3 grains.

In my preliminary load testing with these bullets at 20-25 yards, I fired four six shot groups and here's how they fared:

Beartooth 8.2 grains Longshot 2 3/4 inch group

Beartooth 9.4 grains Blue Dot 2 1/4 inch group

DoubleTap 8.2 grains Longshot 4 inch group

DoubleTap 9.4 grains Blue Dot 3 1/4 inch group

So, based on the consistency of the weight between the two bullets and my preliminary testing, it looks like the Beartooth with Blue Dot is the most accurate load for my G40. This spring I will bump the Blue Dot load up to 10.0 and I'll also try Accurate #9 as well. It will be interesting to see what happens.

Hope this info helps someone in their load development.

Fltbd's post on powders for accuracy has got me to thinkin. I've read Blue Dot is temperature inverse, meaning it generates higher pressure the colder it gets. I emailed Alliant and asked them about it but didn't get a direct answer. I've also read, ball powders like Accurate #9 can be difficult to ignite in cold weather. So, I'm gonna do a test since I live in a cold weather climate just outside Fairbanks, Alaska.

I have two chronographs and the CED Millenium won't work well up here during the winter as we don't get much daylight here in interior Alaska. So, I'm gonna use my magnetospeed to overcome the light problem. Unfortunately, that means I can't use the 10mm as it is an autoloader and the Magnetospeed won't work with autoloaders. So, I'm gonna load up 20 rounds with Blue Dot and CCI 300 primers and 20 rounds with Accurate #9 with CCI 350 primers for one of my 44 magnums.

I'm gonna cold soak 10 of the Blue Dot loads and 10 of the Accurate #9 loads along with the revolver overnight and shoot em to see what kind of velocities I get. Then I'll take the revolver and the remaining 20 rounds of ammo to our local indoor range to see how they shoot at room temperature. A comparison of these shot strings should give me some idea as to whether Blue Dot is indeed temperature inverse and whether or not Accurate #9 is difficult to ignite in cold weather. The charge weights for these powders in the 44 are obviously higher than the 10mm, so my logic is if they ignite and don't get spikey in the 44 magnum, they'll be fine in the 10mm with the same primers. Conversely, if both powders act squirrely in the 44, then they just might do the same thing in the 10mm.   

I'm gonna wait til we get a cold spell well below zero Farenheit to simulate colder weather than I would normally hunt in to test these powders. I might just add Longshot and 800X to the test too as these can both be shot in the 44 magnum as well.

I'll post the results here for those who may be interested. I'll start loading up some rounds this weekend as it is just above zero Farenheit today...man I love global warming. Sure beats 40 below...   

My rationale for doing this test is if Blue Dot turns out to be the most accurate powder for my 10mm and it does get spikey as temperature drops, then I will deliberately load with a less than maximum charge to give myself some wiggle room for pressure, so I don't end up Blacktail deer hunting on Montague or Kodiak Island with a magazine full of proof loads! 
===============================================================================
I modified this post with the results on 12/25/15. The first five shot strings with each powder are ladder loads and the next five were at the maximum load of the tested ladder series. I hadn't loaded 44 magnum with these powders before so I wanted to give myself some wiggle room.

Average Velocity 1413 fps                Average velocity 1292 fps

These results aren't really statistically significant but I'm gonna jump to a couple conclusions based on these tests. First, Blue Dot appears to be a lot more temperature stable than I anticipated based on what I had read. It did lose some velocity going from 70 F to -15 F but it definitely didn't appear to universally increase in pressure. At least the velocity didn't seem to indicate an increase in pressure.

Lastly, Accurate #9 lost substantially more velocity than I anticipated. I don't think it is more difficult to ignite this powder as I didn't experience any hangfires or anything out of the ordinary. It just seems to have lost a lot of velocity.

I'll be doing more load development in the spring with the 10mm and at this point I'd be pretty comfortable using Blue Dot. Hope everyone has a Merry Christmas.

The safety of using the 6 inch G20 KKM and Lone Wolf barrels in the new G40 came up on another thread. I emailed both KKM and Lone Wolf and here are their responses. Note: I've been using my KKM G20 barrel in my G40 with no problems thus far.

KKM's response: "We think the barrels are compatible, so we heard.  Until testing these ourselves we do not recommend using them (just in case)."

Thank you,

Lone Wolf's response: "Well here's the thing, the barrels measure the same, we have had customers use them, but WE have not tested them. The customers who have done it have said they work great."

So, there you have it folks. Neither manufacturer has tried their G20 6 inch barrels in a G40. KKM currently recommends against it while Lone Wolf doesn't make a recommendation.

You be the judge. I'm gonna keep using mine until I see something which concerns me or KKM produces a G40 specific barrel and can articulate why it is better than their G20 barrel. What you choose to do with this information is your decision, I'm not advocating any position, just sharing information.

10mm Hunting / 10mm Handgun Hunting with a 1911-5 or 6 inch barrel?
« on: June 27, 2015, 09:39:08 AM »
I'm a relative newbie to the 10mm. I've owned a Glock 20 and have a Glock 40 on order. For those of you who shoot the 10mm in 1911 platforms for hunting, do you prefer a 5 or 6 inch barrel and why? I'm considering buying a 1911 in 10mm as well and am kinda torn between the 5 inch barrel for easy carry for hunting and the 6 inch barrel for better sight radius and velocity. I would assume the difference in velocity would be anywhere from 20-50 fps? 

This handgun will be used strictly for bear protection while hiking, fishing, camping and for hunting here in Alaska. I'll be handloading Double Tap and Beartooth 200 WFNGCs, (whichever shoots best) so function and reliability are critical. Both worked just fine in my Glock 20 so I'm hopin they'll do the same in the Glock 40 but I have no experience with the 1911s.

Any insight you can provide will be greatly appreciated.
