what would be one of the easiest to make, and most efficiant or best round that i could go with forming 243 brass
.308 is the parent case for .243.
ok i want to shoot something made from 243 brass something easy to form or make wanting to shoot long range coyotes, paper, whatever. have thought of the 243 ai, but have also heard about soo many others out there. what do you guys shoot or think
22-243, 243AI, 22 midlestead are the first 3 that come to mind
6mm CBX
Steve
how bad is the round count on a barrel for the 22-243 middlestead
and whats the cbx
no personal experiance with the 22-243 middstead but I imagine it would burn a barrel about like a 220 swift.
The CBX is a cartrige I designed and built, basically a 6-250 AI with a longer neck. Pushes a 107 seirra @3300 with good brass life and great accuracy.

steve can you pm me
Nice long neck on that CBX. Another good one seems to be the 6CM. I did some reading on it yesterday and it has the velocity of the 6XC but with better barrel life. As much as 3000+ rounds and still at 1/2MOA.
The 6CM is basically the same thing as the CBX. Only difference is the CBX has a 40deg shoulder and the CM Has a 30deg. The CM would be a better choice as it has dies and reamers available. The CBX you would have to have a reamer made(which doesnt cost any more if you have a print than a standard reamer) and you would have to have a sizing die reamer ground.
I used a 6-250 reamer ran deep and a seperate necking/throating reamer to cut my chamber. The sizing was done with a .243 AI die that I cut down but, it did not match the chamber well. so i had some sizing issues. Shot it in F-Class for a year and done well with it. I went back to the 6-250 AI for less trouble.

what rounds are there that i can make easily from the 243 case? i am wanting to stay with the 243 since i have about a 1000 pcs of brass
the other round i may be thinking of is a 6-284 tell me what you think
Dude, if ya got 1000 243 brass it's a no brainer-- 243AI.
You could do all kinds of things with 243 brass......just depends on how much work you're willing to do and how much you want to spend.
If you're wanting to keep the hides on a Kyote, the 22-243 Middlestead would be OutlawKyote's recommendation, and he knows of what he speaks.
Neck it up, neck it down, blow it out, push the shoulders back, or just a simple AI would be nice.
let's start to narrow it down, what is your favorite bullet caliber?
i would like to do something in the 6mm or .224
am thinking of the
243ai
6cm
have kind of thought of
22-243
don't have brass for but thought of
6-284
The 6mm-.284 is based on the .284 Winchester case, .243 won't work. My current favorite on the .243 -.308 case is the .270/08 AI, .270 Winchester ballistics with 10 grains less powder in a short action. It is easily formed from .243 brass and so far has proved accurate and easy to load.Quote:

bob t i do understand the 284 is not the 243 just was saying i had thought of that round but have no brass for it.
i am thinking i am going to go with the ackley
what is involved with making the 22-243
22-243 and the 22-243 Middlestead are 2 different cartridges.
22-243 is just a necked down 243.
The Middlestead has a 30* shoulder and maybe blown out a bit.
.22 cal barrel chambered for 243 brass. neck down the brass with the appropriate die to hold .224 bullets.

finding affordable dies might be hard.
maybe for now ill just stick with the 243 ai
i want to push some 105's so am thinking of getting a 8 twist
how low do you guys think i could go with bullet weight wise?
Heres what I'm working on now.

for people that shoot the 243 ai what do you shoot( load, targets or animals, ranges,ect) tell me about your set up too please
does anyone shoot the 22-243, or a 6-284? maybe while i am at this build i may get some ideas for another
If I were you I would do the 243AI for now. Buy another action later and then start on your 6mm-284 or 6.5-284(my personal favorite that I will be hopefully starting on soon as I finish the current rifle build). Be careful though. Savage's make it all too easy to build a crap load of great shooting rifles vs the other brands, as there is so much that the gun owner can do themselves, without the need of a gunsmith.Quote:

Then I had Kevin Cram at MCR ream it to a AI and do the Pillars and bed the stock along with a lift kit install. Should be fireforming some brass Saturday and some load work Sunday.
pa hog
you will have to let me know how it does what are you loading up for it?
105gr A-Maxs and 107gr MatchKings
i am intrested in the a max's or the bergers, i will be trying to hear what your results are
Ditto the above mention of the 6mm Super LR, just a thought of something other than a straight 243, better than the 243AI as there is no fireforming and all you do is run (size) standard new 243 Win. brass through the 6mm Super LR sizer die and your ready to load (dies available from Redding). It is basically a 1/10th inch longer 6XC. Same case capacity as a standard 243 and pushes the 115 DTAC at about 3000-3100. Very tempting for my next 6mm barrel.
http://www.6mmar.com/Super_LR.html
Just a std 243 and RL17 (and GOOD brass) *should* be able get you to 3300 no problem with 105-108's.
RL17 seems to the magical fairy godmother of velocity for those size cartridges regardless of bullet weight.
6CM, H1000 mild load 3152 fps, 115 DTAC, great barrel life , excellant accuracy.
AI would be the easiest if you want to stay in the 6mm area. load it and shoot it. eject the newly formed case.
there are also a couple guys that are playing with 270 bullets in the .308 case.
factory rounds on this case are
.243 6mm
.260 6.5mm
7mm 08
.308
anything in between has been made. just pick
And 338 Federal and 358 Win!Quote:
