Home Forums Hunting & Shooting Custom Rifles & Wildcats 20 cal cartridge formed from .243 brass ?

I'm looking to have a 20 caliber rifle barrel assy for my Savage Impulse Predator .243 chambered rifle.
I've been using a turn bolt rifle chambered in 20 practical for my restricted area predator hunting needs in NY state.
I would like to use the Impulse rifle for all of my predator hunting and swap barrel Assy's when needed, but Savage doesn't offer a .223 bolt head for the Impulse yet or maybe never, so I'd like to find a 20 cal cartridge that's based off of the .473 OD rim dia of the .243 that doesn't need to much work to form it or special magazines to feed it.
The reason I went with the 20 practical, was because of the minimal work needed to form the case and it feeds from any .223 magazine without modification.
I've searched, but have come up empty in my quest.

Bullets matter wayyyyyyyy more than headstamps and 20's are a bitter pill. Hint.

You are pissing up ALOTTA ropes. Hint.............

I speak and read four different languages, yet I don't have a clue on how to decipher this reply ?

There was a few guys that built .20 BR's back when people cared about the .204 bores. But I see what you need to do - it's either that or a .17 during NYS deer season unless you go rimfire or shotgun.

Cite any/all words that you find "too big" or "too Technical" and I'll use lesser versions,just for you. Hint.

As an aside,STUPIDITY isn't an "advantage" and now even you "know". You are doing "Great!". Hint.

Fhuqking LAUGHING!............

I'm looking for information, So please refrain from posting here if you have nothing to contribute or please contribute in a language that a mere mortal can understand ?

dznnf7 thanks for the reply.
I looked into the other 20 cals offerings, but the multiple forming steps and magazine feeding issues are a turn off, not to mention the price of the brass you need to form them from.
Not a fan of the 17 cal.
Have had no issues killing coyote with the 40Gr V max and I have a lot of them, so I'd like to stick with 20 cal.

scoots,

Your STUPIDITY rests upon your narrow shoulders and is nobody else's "fault". Hint.

Put his ass on ignore. He knows way more than any of us mere mortals.

bitchlambert,

Ain't it a fhuqking hoot,that even someone as fhuqking STUPID as you,KNOWS better than to try and talk rifles. What were the "odds"?!? Hint.

You Melting Snowflake Professional Victims,are a fhuqking RIOT! Hint.

I'd think the 22-250 would be a place I would start -- a 20-250. Or if you don't like the shape of the 22-250 case then 20-250AI.

The BS is the first member on this forum I've had to ignore for posting BS.
I did find 20-243 AI chamber reamers available from PT&G, but no brass or die.
Lee could make a die set, but I need brass to get it made.
I could also ask my machinist friend that made the quick change Impulse barrel parts for me if he could make a .223 .378" rim dia bolt head.
It would probably cost the same as buying the reamers, die set and brass to form into the 20-243.

No BS from you Bugger and thanks for the 20-250 recommendation.
It has the .473 rim Dia, short action, feeds from mags nicely and one step brass forming like the 20 practical.
Your contribution is appreciated.
Now another journey begins.

scoots,

You are in soooooo very fhuqking far over your pointy head and crossed-eyes,that it is simply fhuqking MAGNIFICENT. Hint.



Fortunately for you,Imagination and Pretend are free,so even YOU can "afford" to "contribute". Hint.

Another great contribution to this thread.... Hint
Thanks for the links.
I think I'm settled on the 20-250 cartridge, as I have several hundred 22-250 cases and an RCBS die set.
Traded the 22-250 rifle for a thermal spotter years ago and remembered I had the components stashed away.
Sometimes it's not so bad being a horder.
I will be ordering a barrel from preferred barrels after the season is over next year and have the rifle ready for the fall 2023 season.

scoots,

The ONLY fhuqking things you are going to "shoot" are your mouth and Imagination...you "lucky" kchunt. Hint. Congratulations?!?

Dangle a pic of said die set,if only to correlate that besides being a Drooling CLUELESS Fhuqk,that you just also "happen" to be a Lying Piece Of Fuqking Schit. Hint.

Don't forget,you "can't read this". Hint.

I built a 20 tax before the 204 came out. Great calling cartridge and coyote killer to 400 yds. I like it and the 17 rem but they run out of steam after that. Unless someone makes 60 or 70 grain bullet in 20 cal, all you will gain is a few yds and about 1/4 the barrel life. I think the 20 tac/ practical is the optimum case size for the 20 cal. Just my opinion

Your 20Tac was THE first .204" any of us had ever seen. Now there's .585 BC's in .224" and who woulda EVER guessed that?!? Hint.....................(grin)

Those might be fun to tinker with

A sub .300 BC 48gr 20cal.,is simply fhuqking HILARIOUS! Hint..............
