My latest .243-06 30 Imp.

[Apex Custom Rifles]

Well I have built myself a few rifles but this is that latest one. It is a .243-06 with a blown out case and 30 degree improved shoulder.

Here's the specs:
-FN commercial action
-Rock Creek #5 countour 1-8" finished at 26"
-Sako trigger
-Richards Microfit dual grip thumbhole stock
-Devcon bedded, pillared, and floated.
-Currently wears a Nikon Buckmaster 4.5-14x40AO

The gun weights in at 11.5 lbs fully loaded.
Finally got a load that works.
First photo is of my 100 yard group, and the larger one is of my 550 yard group last weekend. I also went out today and shot 3 at 600 that went just over 2". I'm happy with it. I shot a doe about a month ago with it at 250 yards. This is my main coyote gun, and deer rifle when I decide to use it.

I'm shooting 105 A-max at 3,250 fps.

Maybe tomorrow, I'll get a current photo all finished up and wearing glass.

Nice rifle! Please do post a picture of it when you get the scope on.

I built a nice 257 Roberts on a Polish Mauser a few years ago. They are fun actions to work with, with all of the after-market stuff that is available for them.

Here's the photo of the rifle finally done minus the hot blue. Mausers are nice for their bolt on stuff, but with this one, there wasn't really any bolt on anything I guess other than the rings and bases. It is nice to have many options to make your rifle the way you want it. This was my first experience with Rock Creek barrels and I am extremely pleased with how well it machined and especially its accuracy.

The second photo shows some of my fully formed .243-06 brass next to a .243 win case both loaded with 105 A-max.

Very nice! Your rifle looks gret now tha it is all together. That's a nice looking cartridge too.

I put a Gentry Model 70 type three-position safety on my Mauser. It really makes a difference in the looks of the rifle. Purely cosmetic, but looks great.

I hope you enjoy your rifle!

Awesome looking cartridge and rifle. Only thing you did wrong was to not call it a 6mm-06! I bet that thing is a lazer!

Yeah, Tomato tamaato. I use to call it 6mm-06 till I met all the in-laws that go by .243-06.

Thanks for the compliments.

It would be a great varmint rifle at the longer ranges

NICE!
Alot like my 243SRC. Necked down and blown out 25-06.

Im pushing a 105gr to 3400fps and a 75gr HP to 3800fps. You did it right with a 1:8 twist. Mine has a 1:10 Hart barrel that is 30" long, I really wish it had a 1:8. If I ever build one (traded into this one) I would do a 28" with a 1:8. I love the round its a killer round for sure.

dk,

thanks,

I'm using .25-06 brass necking it down and fire forming it also.. What is the shoulder angle?

3,400 fps with those 105's is cooking. I suppose with that long barrel you can make those work in that slower twist barrel. Nice looking rifle too!

 

[dk17hmr]

Shoulder angle is a good question. I would guess 30-35 but Im not sure, I didnt design the round and I can seem to find specs on it.

Before I started with the 105's I was using Hornady 75gr HP's pushed by 56.5gr of H4831sc for about 3800fps, it just flattens critters. My brother took an antelope with it a couple years ago at 445 yards and it looked like someone pulled a rug out from under her.

The 105's I am using (I think data not infront of me) 53.0gr of H4831sc for just under 3400fps. This is probably going to be the first rifle and load I hit a 1 mile target with. I have a friend hitting 1 mile with a 6 Dasher and 105's and 115's so I think I can do it with the extra 600fps I am getting.

Do you have to trim your cases? If I recall correctly, he may have taken the 243 SRC chambering and lengthend the neck to allow for less trimming of the neck. I don't have to trim necks with mine. I think the 243 SRC is 30 degree give or take a few degrees.

I also could have done a 243 SRC because he has the reamer, but I can't recall exactly what the advantage of my chamber is. Ballistics wise, they must be identical.

 

[dk17hmr]

I do trim my cases just to true them up basically. I think my trim to lenght is 2.460", once its all to lenght I debur the flash hole. After I fireform I neck size than turn the necks, again just to true them up. I just formed up some brass on 30-06 LC 69 brass, orginally I used FC 270 brass but I was new to this wild of a wildcat and was over sizing and causing to much headspace. After I got that figured out I had pretty good luck with 270 brass except for the only getting 3 loadings out of it. I switched to Winchester 25-06 brass and got 5 loads out of the last batch before primer pockets got loose to loose. Hopefully I get several loadings out of the LC brass.

I think we are shooting ballistically identical rounds (in the same lenght barre), there might be slight differences in the case though. I love mine its a killer round.....55gr NBT at 4500fps send pdogs to low earth orbit.

Just wanted to post a little update. I haven't shot this rifle in quite some time, so I took it out the other day and shot at 600. The link below is a video clip of the adventure. Not my best day out, but OK for not shooting in several months, gotta brush some rust off!
