22-243 conversion

[mattparliament]

Hey all, I am going to switch a 223 barrel I have to a 22-243 of some sort.  I know that there are several variations of the 22-243.  Which one would you choose and why?  I really don't want to do PITA fire forming.  Thanks guys.

Guess that for some reason (censored) is sensored, must be a filter gone crazy, could be a joke the hacker is playing.  Larry

SS,     :-D  :-D That's 5 down and 495 to go. That's funny, I don't care who you are.    :-D  :-D

hey, .308!

man, i can't believe we got right back into this kind of a 'burn 'em up' caliber in less than a week of trying to put out that last fire!

straight-up now, i saw on one site (reloadersnest.com?) a cartridge called the .240 incinerator!  :shock:  :shock:    i think it was a link from 6mmbr.com, but i can't remember any more than that.

.240 Incinerator!  :eek:  :eek:  :eek:      why do we even bother building the rifle when we can just build fires and throw metal in on top of 'em?

i better shut up.

take care, .308,

ss'   :oops:

OK, lets see if this is on the censors list:  I stole this post from another board, so I will credit the post to the origional writer.

Haven't used the Middlested version
 
but, have built rifles and use one in a straight .22-243. It seems to be at its best with the 80 gr bullet and a 8 twist barrel. The .22-243 uses the same shoulder angle as the parent cartridge with the shoulder in the same position. The Middlested has the shoulder moved back with a longer neck and a different shoulder angle. The advantage of the .22-243 over the Middlested is that there is no fireforming required resulting in one less round that you have to use down the barrel. Full length size the .243 case and you are ready to load and shoot with your regular load. No need to use a reduced load as you would need when having to fireform a case.

 .240 Incinerator!  :eek:  :eek:  :eek:

 :-D  :-D  ,  

[quickdtoo]

Don't laugh, it exists...at least in someone's mind!! :roll:  It's a .264 Win Mag necked to 6mm. 35 degree shoulder and minimal body taper.

quickd' / .308

the load for that "Incinerator" :shock:

78 grs' of imr(?) 7828 behind a 55 gr' Nosler Ballistic Tip for :  4680 fps :eek:

you have to keep left-clicking on some numbers to get to the actual load, but it's there.

i only put 67 to 69 gr's of imr 4350 into the 7mm Rem' mag's i loaded for a buddy!

next thing you know, some l-u-n-a-t-i-c will come up with a .224 VOLCANO!

i've seen enough,

Just go ahead and build your 22 Midlestead it will do good with a fast twist and heavy bullets and slow powder. Most people that squawk about them have never used one it is not all that much different than a 22-250AI.
 
Consult Ken Howells book and the 220 Howell a low pressure High velocity 22,

There is no fire forming for the 22Mid. all the case forming is done in the die with one stroke, outside neck ream and go shooting.

Thank you for the helpful information, I really appreciate it.  The bottom line is that I AM going to build a 22-243 of some sort no matter how silly it may seem to some.  I realize all of the things involved in having a wildcat, along with the fun.  Again, thank you for the helpful info, I really appreciate it.

[trotterlg]

I'm with you Fred, I think it is alot more fun shooting something that shoots more like a Laser than a Mortar.  Larry

"amen" says my 243 going 4000+

[trotterlg]

When I was at the range yesterday there was a guy with a NEF 45-70.  When we were putting out targets I watched him lean his target board back about 15 degrees, and then walk back in.  I asked him why he did that, and he told me it was the only way he could get the bullet to go straight through the paper so he could get a good measurement of the group size.  Larry  :wink:

these are from reloadersnest.com

22-243 middlestead used 45 gr's of imr4350 to get 4250 fps out of a 29" barrel with a 55 gr' nosler bt!    who has a 29" barrel they want to carry around?   load#10026

22-250 ackley improved used 34.5 gr's of imr 3031 to get 4125 fps out of a 26" barrel with the same 55 gr' nosler bt.    load#6563

i still say, stay away from the .243 and its ilk when necking them down to .22 cal.....you'll be so overbore that you can't realize the potential of all that propellant, and you will burn out the barrels.

fwiw:

i'd think that a 60 gr' Horn' spire point out of a .22-250AI' would be a deer slayer out to 250 yds' for deer that weigh 270 lbs IF bullets are properly placed.    the problem would be that such high impact velocities at short ranges would create bullet blow-ups, possibly, on some parts of even a whitetail or a mulie.
