Does anyone know 243 load that is above max?
 

I am going to start loading for my 243. I was wondering if anyone knows a really good Hot load that is a little above max but still safe. I will start out light and work my way up to this. I was just wondering what a good load is! Thanks

i will probably either be using IMR 4035 or 4064 powder. Thanks! If you have any other powder suggestions let me know! Thanks.

i have loaded above max on a few things my .243 win, my .270 win, and my .300 wm
the only one i have got anything out of was my .300 wm and that was not much

the .243 and .270 all got worse on paper they did well in noslers mid range loads

How long have you been a handloader?

Now there's an oxymoron for you.....

Ok sorry. Lemme try this! Does anyone know a good consistent hard hitting 243 load that works well on deer!

I have had good luck with these 2
IMR 4350 (40.5 gr) and nosler 100 gr partition
RL 22 (41 gr) and 100 gr partition

they are for my wifes .243 and she gets 1.5 moa at 100 yards great for antelope and muleys i am sure they would take out a whitetail also

however i will for warn you what shoots great in on rifle can be a total different ball game in another

i would suggest you get the reloading manual for the bullets you want to shoot and work up a load for yourself it is more fun to know you worked it on your own

if you need a page or two of loading info from nosler or speer shoot me an email and i scan one for you

RE: Does anyone know 243 load that is above max?
 

NO! But let me qualify that. NO LOAD THAT IS ABOVE MAX FOR YOUR INDIVIDUAL RIFLE IS SAFE TO FIRE IN THAT RIFLE! However, just because a particular loading manual says some such load or the other is max., doesn't mean it is max in your gun! It might be max., under max., or dangerously over max., IN YOUR GUN!!!

The only way you'll be able to find this out is by developing the load, 1/2 a grain increase at a time, in your own rifle!! If you use some data that works in somebody else's gun to go "over max" in your rifle, you are a fool!!

RE: Does anyone know 243 load that is above max?
 

if you need to ask for advice for an overmax load then havent been reloading long enough to do so. Overloading is a risky business and should not be lightly. I did it in some .357mag, but that was with lil'gun that gives low pressures to start with and I had another 10,000cup above my loads to get into the real max of a .357mag in a large framed handgun. accuracy dropped off fast though and i went back to the published max.

RE: Does anyone know 243 load that is above max?
 

the .243 with good 100 grain bullets is totally and completely adequate for taking whitetail deer (and a lot more) as-is!

Use any reputable reloading manual and develope a load.....chances are you'll end up about 3000'/sec.....if you achieve 3,200'/sec your gain will be insignificant.....Even at 2,800'/sec it'll be totally adequate for deer.

If you really want a faster 6MM get a .240 Weatherby.....but it still won't kill deer deader or faster than a .243 Winchester loaded to reasonable pressures.

If ya have to try and make one caliber do something it wasn't meant to do, you are either going to blow things up or hurt yourself. Buy something bigger rather than take unneccessary risks.

RE: Does anyone know 243 load that is above max?
 

Many years ago when i bought my first chronograph i figured out that MANY times even the max load in a load book (especially the older books) actually gave NO improvement in gained fps.. over a load that was 1/2 grain less powder!! And, in many cases the extra powder actually caused the velocity to go down, with VERY erratic velocity from shot to shot!!!

Loading over MAX, "even if" you gained 50 fps, (wich i doupt you will) what would you ACTUALLY gain at 100 or 200 yards?????????????? All you will "really gain" is more stress on the gun and brass, for for pretty much ZERO gain!!!! To be blunt, it's a STUPID idea!!

This is all very true, but I must point out that there are MAX loads and then there are MAX loads! Just because some book says "X" amount of "Y" powder with "Z" bullets is a MAX load, does NOT mean it is MAX in your particular rifle! It could be very much OVER MAX in your rifle, or considerably UNDER what your gun thinks is MAX! The only way one ever finds out which situation pertains to his/her gun is by starting low, and working up a load a small amount at a time. In a cartridge like .308-size cases, 57mm Mauser cases, or those in the .30/'06 class, increments of half a grain can be safely used. Smaller cases require smaller increments! You might get away with full 1-grain increments in the larger Magnum-sized cases.

In my mis-spent youth, I did stretch a primer pocket or two doing this. These days, I stop increasing charges when I get the accuracy I want, which in a hunting rifle is anything at or below 1 MOA. My goal for pressures is that my cases need to last at least ten reloadings AFTER the first shot to fireform the brass to individual chambers. ANY load that permits your brass to last for ten reloads in a given rifle is plenty safe enough for continued use IN THAT RIFLE!

I have a Savage 10G in .243 Win. I just finished load development for the 105 gr. Hot-cor spitzer. Now the Speer Manual No. 13 says that starting loads for IMR 4350 is at
34.0 grs. @2418 fps, and max is 38.0 grs. @2651 fps. The #8 manual says that starting loads is @ 38.0 and max is @ 42.0. So based on that I went with Speers #8 and finally settled on 42.8 grs. of IMR 4350 with a velocity of 3025 fps out of a 22" pipe.Groups measure 3/4" to one inch. Case inspection shows no abnormalities( split mouthes, seperated heads) and primer pockets are tight after 5 loadings.:D

Start off with a min load and work them up. Trust me Even If you load up 1 or 2 rounds to make sure your gun can handle it. I agree with the other guy if you want more power in a 243/6mm buy a 240 weatherbee mag(good luck finding a gun), or a 243 wssm, or 6mm remington.

I have been reloading for 15 years and my father has been reloading since 1956. We both just got schooled on this one. I just bought a used Ruger M77 in 300 Win Mag from a coworker. His father in law bought the gun new in 1975. He fired it 3 times, could not handle the recoil took it home and bought a 270. It sat for 20 years in his gun cabinet. Then my coworker bought from him fired 14 rounds and said too much recoil. This gun has only been fired 17 times(yes its mint, perfect no scratches, have the half boxes of ammo 17 missing, no BS).

Using once fired win brass tumbled, cleaned, and trimed. I loaded 2 diffrent loads each to the min load with 180 grain speer bullets. I loaded 10 rounds with Hogdens 4895 and 10 rounds with Imr 4350. With rifle loads I weigh out every load and I use an old Rcbs Jr press(very slow). I went to the range and fired the 4895 rounds first.(At the range I fire 1 round a minuit to let the barrel cool down). Damn this gun kicked as hard as my dads 338 win mag. My dad laughed at me and said get used to it kid(I am 29). Then I fired the Imr 4350 and Damn it kicked so hard it almost fell off the sand bags. Then I could not open the bolt. I had to wait 5 minuits for the barrel to cool down before we could get the bolt open. It was a bitch but with 2 people we got it open(I am luckey that I only had 1 round in the gun) I split the neck and started to push the primer out of the case. The back of the case was deformed from the pressure. This minimum load was listed in the speer #14 book.

We had the gun checked and the bore is .0015 smaller than it should be(tight bore). This explains why the previous owners hated this gun. Tight bore= increased pressure and recoil. Commercial manufactures load rounds to a happy medium so if one gun has a tight bore and one gun has a larger bore they both will be safe.

So start off lower and work your loads up. Use your head and dont trust anyones loads. Use them for refrence only.

deerslayer just a word of caution. Max is there for a reason. I've only ever had 2 rifles that shot well at max or near max loads. My 270 and 300 WM.
Some rifles just don't like max loads either. Don't be overly posessed with velocity. Accuracy is more important.
My 243 just loves 40.5 gr. of IMR4350 behind a Hornady 100 gr SP.
