Thanks to Jeffe for loaning me a set of dies! started out low and will work up. the first load to go was 390gr cast rn(458124) 42 gr/aa5744 for a est.1800fps nice lite load shot well was all shot offhand but we where backing clay birds out to a 100yds having fun Clint

Clint,

.458 AR is a wonderful cartridge! I use a 435 gr cast FPGC projectile lubed with Carnauba Red with 50.0 gr of AA 5744. Getting abt 1 MOA with it.

Wait until you see its performance on game. Amazing!

The medium game hunting load is a 425 gr Rhino solid shank bonded core bullet behind 85 gr H335 ignited by FED 215s. On Quality Cartridge cases it gave m 2400 fps.

Rifle shot a clover leaf at sight-in in RSA.

Knocked a Blue Wildebeast off its feet at abt 60 yards and he only twitched a little. Hit an Eland at 186 yards (lasered) quartering away. Bullet went in behind the left leg, across the chest and out the right shoulder. The fella stumbled and was down.

Jeffe outdid himself with this design!

I will soon be joining the 458AR club. Have just ordered a bunch of 458AR brass from Quality Cartridge. Barrel has arrived yesterday and reamer is on its way, should arrive in a week or so..
Looking very much forward to play with this new toy..

Great to hear!

a 425g "medium game load"???

Wow. You guys are something. I top out at .375H&H 300's.

Think I'll go back to the medium bore forum.

Good hunting (of Stegasaurus, or whatever).

Thanks mauser.. they aint bad to shoot ...
little 425 at 2400? that's just 416 rigby levels of recoil


458 AccRel Brass on Midwayusa!

Clint,
take the chrony out ... rem 405s took a bit more to get 1800 than 42 gr ... but that just means you have room to run them!

Nice with brass from Midway eh...
What was the case volume of the 458 AR brass from Quality Cartridge Jeff??

Mike who,s cast boolit are you using? will you sell or trade for a hand full so i can try them in my gun. Thanks Clint

Well done Clint, the AccRel line up is a hoot to shoot.

As far as Jeffe loaning you a set if dies, he sent me his new Hornady ones and waited till mine that were on order got made to replace his, he really is a nice guy .

due to the Dr. not wanting me to drive to the hoot an shoot i went to the range Saturday. spent 5hr a shot 53rds from bench and offhand got it sighted in and got a good start smoothing out the inside of the barrel. the groups got smaller the more i shot and cleaned. the last was just over a 1" at 50yds and got a 3" at 200yds. one of the highlights of the day was try a new to me boolit and getting good groups(now i have to order a mould) also found out the new scope i got a few years ago will not hold poa. glad i had a backup to use! this gun is a blast to shoot and sure gets the other shooters attention. one guy was shooting a 4"rock with his .223 on the 100yds berm ask if i could hit it well the first shot we had gravel! Having to much fun Clint

Sweet, Clint -- Did you switch to 375 rum cases?

yes trimed to 2.650 9grs of 700x fill with cornmeal not a lost case my next move is to find mag primers. the 200yds group sting vertical a sign of inconstant burning. looks like you had a great time sat wish i was there! Clint

just back form the range tried a new load 405 rem/75 /h4895/fed lrmag shot 3 at 50yds into a .263 group recoil was not bad but loud report the 4th shot shredded a water jug the 5th one made more gravel. any idea of the speed of this load? the other load i used was 410 cast/45/aa5744/ fed lrmag this load shot into 1.250" think with a little work this boolit will shot better! will have to dig out the crony Clint

rem 405 with gr of i4895 went 2020 from a 23" barrel, set at 3.280 aol

shot the 458 AR yesterday! found a ranch with meat pigs cheap 40yds base of the skull BIG BOOM FLOP! the guide was in shock ( at the way the ground jumped up and hit that pig!) the load was 410cast fngc/ 45 /aa5744/fedlrmag. will have to shoot this over the crony. the more i shoot the more i like this gun Clint

Clint,
GREAT! Can you meausure the h20 of a fired case? all mine are resized!

Jeffe i got 92.4grs to the top of the shoulder hope this helps Clint

Thanks.. can you do to the top of the neck, tiny meniscus?

should be close to 112 gr

112.6 to the top of the case will not hold more. Clint

Thank you, Sir!

got to shoot over the chrony the last time i got out. 385cast/22/trailboss 1265fps 410fngc/45/aa5744 1725 405rem/75/h4895 1950 400fngc/74/aa2230 2244 hope this info helps.all out of my 21.5 1/18 barrel Clint

Clint,

Sounds like it is going REALLY well The .458 AR is like that ... lovely.

I make my 435's cast bullets in wheel weights from a Ballisti-Cast 1421 LFNGC mold lubed with Carnauba Red.

Works well.

The .458 AR also performs well with bullets cast with the 500 gr Lee .458 gas checked mold.

The 425 gr Rhino at 2400 fps really is a medium load. Recoil is very nice but the effect of game smaller than Cape Buffalo is awesome. I'd go to a 500 Woodleigh for the big stuff.

Clint,
thanks!
What are the OALs on those loads, and I'll post them on ammoguide

oal. 3.285 the next load will be the 400cast with h 4895. want a 400 at 2100-2150 load in the earlier post i made a mistake and typed imr but used H please note Thanks Clint Clint

thanks ..
switch to h335 for higher speeds!

Mike is that the "C457-500-F" mold?

What powder and grains if you don't mind?
