Come on! DETAILS! I see dead critters waaaaay out there!

Details, Detail's. dont leave us hanging here.
I'm drolling over here.

yes we want details lots of details that is a great looking
handgun talk Ernie

Its all photoshop, does not really exist.

That is without details?

The question I asked Ernie was ..."can I have it, please?" and Ernie's reply was..."Yes".....heheheee

Hhmm...I see that the "Battle AX" has arrived!! I'm sure it will bring you lots of...bad joke alert...AX-itement...and I bet it's AX-ilierating to shoot!

Oh...BTW...make sure it does not AX-identally hit you in the head!

Nice Ernie!!!

Looking at the buisness end of that cannon is so intimidating that I'm going to go out to the deck and settle my nerves with a Killians - or three.

Criiipes!

Renster

I like!

Is that from Earth?

Yes....but it's built to shoot PDs off the moon!!

Ha Ha Ha Ha

I think Mr. Ernie could do that off Saturn...

I was going to pick another planet, but I know the minds of people on this forum... LOL

Wild looking brake. Nice!

This type of coolness should not be allowed!! I thought my Rigby looked like a terror weapon, but WOW Ernie!! A single shot tank killing handgun!!

The pic I posted is from Kirby. I actually do not have it, because Kirby wanted to do some accuracy testing before he sent it, but the wind has been howling for the last weeks.
Kirby has done some chronoing with Retumbo (CCI-250 primer) with 225AB's, 250 AB's and 300 grain SMK's. After the chronoing and checking pressures and different MV's he came to the conclusion, that H-1000 would likely be a better powder than Retumbo for the 225 & 250 grain bullets. The AB's have a heavy solid base compared to some other more pressure friendly bullets like the Barnes TSX and Scenar's.

Here is some MV's for the three different bullets:

225AB - 3076 fps
Comparing this data to the Hodgdon's best load for the 338 Lapua with this bullet weight in a 24" barrel, they list 3040 fps as their top velocity so not to bad besting a 338 Lapua in a rifle length barrel.

250AB - 2890 fps
Hodgdon lists the Lapua at 2850 fps with this bullet in a 24" barrel length so again, we matched or exceeded the standard Lapua in a rifle length barrel.

300SMK - 2720 fps
Hodgdon lists the Lapua at 2670 fps in a 24" barrel length, again, we topped that by a decent amount.
Kirby said that H-1000 may even work good for the 300's, and may get you more velocity but with this bullet weight, but to be very careful and not push things to hard. With a 300 gr bullet, the pressure spike can get very aggressive with faster burn rate powders.

Recoil wise, Kirby said the 225's were warm and fuzzy.
No comment on the 250's, but he said shooting offhand with elbows bent (see through the scope 4.5-14 Leupy) he had to have a little force to make sure it didn't come back on him to much.

We have several SP's based on the Lapua, Lapua Improved or 338-300 Rum Improved (338 Edge).
Eric Wallace (Crow Mag) started things off several years ago with a 18" 338Lapua Imp, and now Doug has a standard 338 Lapua, and Neal has a 338 Edge.

I think Doug's is a 20" and Neal's is a 19" or 20" (Help me out guys, if I am wrong here.
This is giving us an idea of what can be done with some very large bores/capacities.
Steve (sscoyote) is the one who pushed me over the edge to do this, so I guess I can blame this project on him Big Grin
This will be the first time I have ever owned a SP that would hold from 97.0 - 107 grains of Retumbo with a loaded bullet.
Once I get it I will be putting a Huskemaw scope on it.


If I get an accurate load with the 300's at 2700 fps (4500 ft elevation, 59 degrees, 200 yard zero, 10 mph full value wind):
------------DROP------10mph DRIFT

500 yards - 7.50 MOA ---2 MOA
1000 yds - 24.50MOA ----4.25
1250 yds - 35 MOA -----5.50MOA
1500 yds - 47.25 ------7.25
2000 yds - 79.25 -------10.50 MOA

I really like the looks of it and can't wait to actually get it.

One more pic:

I guess i'm gonna need a bigger spotting scope now...ehhh?

I betchya' the 300 SMK overtakes all of the other bullets beyond 300.?

It has a .25 less wind drift @ 500 yards than the 225 AB BC .550 does. It has the same wind drift @ 300 yards

Wow--amazing--sounds like u have some choices with it.

That's badass.

My .460 just whimpered and hid in the corner.

That is an incredible piece of ballistics technology.

Thanks guys!
Bad thing, is that it is still windy where Kirby lives:(
Steve, How can you get a bigger spotting scope than those Kowa Big Eyes???
Just for giggles I checked Exbal for impact velocity and ft pounds of energy at 1,000 yards, and it will be traveling at 1804 fps and will have 2167 ft pds of energy.

I need to look up the BC for the 250 grain AB, and do some comparisons there.

where do the wheels go,I dont see no wheels

I don't, know, I haven't been that close to it yet, to see where they attach:)

Awesome numbers for sure. I guess if the PDs are not coming out for the day, you will be able to go in after them!!

Yup, with numbers like that the bullet can hit in front of the PD and blow enough debris to kill the critter.

I was thinking along the lines of morter shells...they may be able to collapse the hole and kill entire dens at a time!

What am I going to do with you two?????

Here is what Kirby posted today:

"Well my friends, today was the day. By good shooting conditions standards it was pretty bad but compared to what we have dealt with for the last several weeks, pretty darn calm, only 10-15 mph winds!!! Only problem was it was 18 degrees when I got up but I decided I had to suck it up and test some rifles and a big handgun before I had customers giving up on me.

For Ernie's XP used a load of 103.0 gr Retumbo under the 250 gr Accubond which proved to be a good comfortable load.

I set up at 670 yards on a lightly snow covered side hill to get the XP close to point of aim. The snow DRAMATICALLY helped me see where the XP hit at as the recoil was enough to jump it off target shooting off 12x but there was a very clear and well defined impact crater left in the fresh snow.

Took three shots to get it close and then I put a pair of shots literally on top of each other at this range. Figured it was time for some longer range. Because it was cold and I wanted to just test her at long range to see if it met standards and then let the real shooter deal with the details, I set up at 1375 yards. There was a 3/4 moa target rock that was laying in the middle of a bare snow covered bowl which was bare dirt under the snow. Impacts would be clearly seen even if I missed the actual impact. That did not turn out to be a problem though as I was able to recover from recoil at this range and see every shot land.

Took a couple shots to see where I needed to hold on the TMR reticle to get close to the target rock. Again, I was not overly concerned about hitting the rock, just wanted to get close and the actual impact in the snow would give me a much better idea of group size then actually hitting the rock.

First shot landed roughly a foot low of the target rock, dead center horizontal. I was dealing with some variable winds from right to left but at my location it was very hard to read them. Second shot was easily within 3" of the first. Third shot landed just above the first two but so close that it still left only a single crater in the snow. I put five rounds total through the XP and when all was said and done, the total impact crater was smaller then the target rock which again was roughly 3/4 moa measured off the TMR reticle. Now figuring that the actual center to center impacts were much smaller then the actual visible crater, I was very satisfied with the results. Especially considering this is a pre-break in barrel and the first load I put through it.

I also wanted to test the barrel when it was warm just to make sure that bolting directly to the barrel shank would not cause any accuracy issues when the barrel warmed up. I found another target rock just to the side of the first one and shot another three shot string while the barrel was still warm. First and third again were so close it looked like same crater impact. Second shot landed about 8" to the left but I totally believe that was blown by the wind as I my right cheek felt the wind pick up just as the trigger broke. Still height wise, it was perfect. All 8 shots had no more then 5" vertical spread on them.

Put her away and am fully confident that she will perform pretty darn well in much more capable hands. These load were with the freshly fireformed brass and it appears that muzzle velocity was very consistent, if it was not, it made no difference on grouping at nearly 1400 yards.

I did not test the 300 gr SMK simply because I was under the impression Ernie wanted to use the Accubond for hunting but after reading his post here it seems he may want to go with the SMK. I have no doubt that it will perform at least as well as the Accubond in accuracy, especially when dealing with crosswinds. I have never seen an example where the 300 gr SMK would not shoot extremely well in a sound firearm and this one certainly seems to be that.

All in all, I am very happy with the end results. The XP was quite controllable on the bench. First shot she hit the brim of my hat pretty solidly but once I turned my hat around, it never came close shooting with full field of view on 12x through the Leupold 4.5-14x50mm Mark 4 LRT scope. I am sure 14x would have been just as easy. There was no hand discomfort of any kind but I did start to get a bit twitchy simply because I have not maintained practice with the big handguns and its a simple issue of hand grip control more then anything. The muzzle did not jump much at all.

My opinion was that most of the movement in the XP was caused by torquing of the handgun, something we simply can not eliminate completely with this class of chambering in this weight of XP. In all honesty, its a pretty light handgun for this class of chambering.

Anyway, she is proven to me. Will be heading to her new home in Wyoming here in the next day or so and I am sure you will hear much more about her from Ernie. Seems the double recoil lug design has worked as planned."

Excellent!! You better buy antelope doe tags by the half dozen....get a couple lined up and zing a 300gr SMK right through.

Yup, sounds like a Howitzer!

That gun is the "BOOM"

That's just not right.
