Win 760, Speer 70-grain TNT. I use CCI or Wolf large rifle primers. I've used both Winchester and PPU (Prvi Partizan) brass. Charge weight not disclosed, because depending upon the specific lot of 760 and the specific gun, it can be over-pressure.

H-1000 under the Speer 100-grain BTSP worked fabulously, too (also CCI LR), though stick powders are not my fav.

crracer 712 is an unknown quantity at this point
Only load I've made for the 243 is winchester brass, Remington core-lokt 100 grain bullets, winchester large rifle primer and IMR4350 powder. Don't know the grains right off hand, but if you need I'll look in my notes when I get home.

I use the same load for my 30-06, 150 grain core-lokt and it's very accurate on paper. I've never shot the 243 on paper so I really have no idea, I just know I've laid down 4 deer with the 243 using 4 of these loads. So apparently it was effective.

I agree with Win 760 for bullets under 80 gr.(never loaded heavier)
Haven't found a load that doesn't work, coyotes drop dead!

I have a couple of .243 win. Both Remingtons, 788 and 700. I have shot thousands of rounds, many bullet types and powders. One powder that seems to be most consistant from 80-100 grain bullets is IMR 4350. I now only shoot one bullet and load for chucks to whitetail. No need to readjust scope for different loads. That bullet is 87 gr Hornady BTHP . Very accurate, deadly, look up powder charges in your loading manuel or on a reliable powder site such as IMR. I like to put in a charge that is on the hot side in a good bolt acction rifle.

I have used IMR 4350 & IMR 4895 for many years in my Rem. 788, in 6mm., & my 30-06, .308 & .280 Rem.
I have quite a bit of it in the cupboard.
All the brass i have accumulated for the 6mm has been Remington, but all the new brass I just bought for the .243 is W.W.
6mm bullets I have in the cupboard are, 3 boxes of Hornady 75 Gr. H.P., 1 box of 65 Gr. V-max, & 1 box of 58 gr. V-max. 2 boxes of 100 Gr. Nosler Partitions.
All have worked extremely well in the 6mm, but that doesn't necessarily mean they will work equally well in the .243.
The new .243 is a Marlin X7, W/a Swift 3-9 40mm scope. So far, all I've shot is W.W. 243 WINCHESTER 80GR PSP , & I've been very impressed with the accuracy.

I've used IMR 4895 with 70 or 75 grain Sierra bullets. The 70 grain Sierra BT match shoot better but the 75's are better on ground hogs. Also used some W 760 and 75 grain Speer HP in another Rem 788.

It's pretty plain vanilla, but I've owned a few .243's over time, in fact, haven't been without one in about forty years.

These days, I feed my M77 MKII a combination of loads.

12gr of Trail Boss + 60gr Sierra HP's makes for a super accurate ground hog load in places where nobody wants to hear a full power varmint detonator go off. It gets about 1600fps or so, and is deadly out to 125yds with a 75yd zero. It's a bit too destructive for winter foxes or coyotes if you plan to sell the hides.

H-414 and a Hornady 70gr SX hits very good speeds, and will destroy pests that you don't plan to eat or sell the hides.

Deer and antelope can be efficiently bumped off with a stiff dose of IMR7828 and a 100gr Hornady/Sierra SP, even at 350yds if the 'lopes are spooky. The same bullets over Trail Boss leave tiny holes through both sides of a fox or coyote, and don't make so much noise that other fur leaves the county.

How do they hold up on PA deer?

I took a box of Sierra 85gr BTHP's to eastern WY for a combo antelope-mule deer hunt many years back. It was a windy hunt, even for WY, but I managed to tag a respectable 4X4 mule deer, and a pair of antelope, one on a extra doe tag. The mule deer was a good 275yds out, (pre range finder era), and both of the antelope were over 300yds. The bullet performed beautifully, and I was sure it was the best bullet ever made for the .243. Then the same fall, I shot a 4pt buck in NY, at about 35yds, and a week later, another modest buck in PA at about 50yds, and the bullet was a bomb up close. I went back to 100gr bullets.

I have only ever loaded 41.5 gr of Reloader 15 under a 70 gr Speer TNT hollowpoint for volume varmit loads and had very good luck. I intend to step up and load some 95 gr Berger's although i don't really have a use for then right now. Those Partitions should make one heck of a good deer bulet, i know several guys that use them for everything up to mule deer, in both .243 and 6mm rifles. My best friend swears by 4350 in his .243 mule deer and antelope loads with Sierra bullets, not sure of his load though. I use mixed headstamp brass for my loads since i shoot for volume, but always seperate for number of firings. Federal LR primers are what i use per Speer's recomendation

TMan, I use this bullet because of it's accuracy and versitility. I have made some impressive 300+ yard shots on chucks with only heads peeking out. My son killed a small whitetail buck (100 pounds) @ about 90 yards with this load, and I shot a nice doe little over 100 lbs. @ about 70 yds. Both shots were broadside with nice exit holes breaking ribs causing organ damage with little damage to meat. I have not hit heavy bone with this bullet so I can't report on that. This gun/load is a favorite for tree stand hunting, when I still/stalk hunt, I carry a .308 Win or better.

Well, I've had a lot of good results with Hornady bullets, and I've used them more than any other brand in everything from .22Hornet, to .375H&H. They all do what they were designed to do.

Sounds like the Sierra's are a bit more explosive though. On the other hand, with careful shots they might be a quicker kill than the 100gr bullets.

Always liked the old Nosler 100 gr Solid base but these days I use the Nosler 90 gr E-Tip.Holds together very well and kills well also.When I had a 243 I used IMR 4831.I now shoot a 6MM and use rel 22 with the 100 gr.Never used anything lighter for deer.
