How much H4350? Thats got to be above normal 243 pressures to get that speed?

I've read many on the interweb claim 3100-3150 with 105-107 grain bullets in the old 243 win. Is that real? I don't know. I'm sure they are pushing the edge of pressure if so. May depend a bit on what barrel length its being fired from also.

I hate how it makes you vote to see results.

The first rifle I bought my wife was a package Savage in 243. Tried corelokt and hornady whitetail, both 100gr. We settled on the hornady. Works well enough on the range and the few mentioned sized game (a doe, a couple pigss and a gator). We just don't know any better because we've literally haven't tried anything else. This 100gr whitetail has gotten the job done in the limited usage.

Find your twist rate with a cleaning rod, jag, and patch. If you don't know how, I can explain it.

That's so you are not swayed by other votes. Don't be a sheep.

And, I checked the box that makes it that way. Don't like the poll, start your own.

Thank you, everyone!

My COAL is 2.745 which is the max for my magazine

I haven’t seen any pressure signs, I based my speed off of a ballistic calculator, 100 yard zero and 8” of drop at 300 yards which is the furthest I could shoot that day. I plugged in the info on the calculator and played with the speed until the calculator matched what I saw on paper. Once deer season is over I plan to shoot it at longer ranges and refine my dope but it’ll work for now. Or maybe Santa will bring me a chronograph

FYI, you can have you speed plugged in 200 fps wrong and still be matching the calculator at 300 yards. I really don't hone in on MV until I get to 600 yards, typically. I've got a chronograph, but I trust DOPE to 800 yards more. I get it, not everyone has that available to them.

Once deer season is over and I can guarantee that I’m the only one on the lease I plan to shoot 350-750 yards to a tank dam to get more accurate dope

Amen...I still have a few and hoard the appropriately....

Still mad at Nosler for discontinuing the Solid Base bullets!

I have two Ruger 77 Tangers and both required a bit of tuning and glass bedding to get them to shoot. Especially the 257 Roberts. I would look into that before I was stuck with one bullet weight.

Several apps available for your phone, this might help with your quest.
Hornady, Nightforce lots out there.

Lol, good point,

The real question is will you be able to load something not heavy for caliber? The 280AI and 7wsm are the only two I've seen you vary...you shocked me when you did them both

Most people do not have the twist to stabilize heavy for cartridge. So yes, I will load what will work for most.

(.280 A I. Is the only one that wasn't loaded heavy. The 7 WSM got 180's )

This has been an interesting read, but I do wonder why the interest in what bullets are being used in the 243.

People need ammo. I'm going to make some.

Worked on load testing 7mm-08 and 154 gr SST yesterday for the same reason. Not a bullet I will use, but other people do, and I have quite a few.

100 grain Winchester Power Points.

Its hard to go back to the light fast bullets after shooting the high bc ones. So much easier to connect at distance, and still great expansion if you pick the right bullet. My Berger VLD's still fragment rapidly at extended ranges.

Hornady 100 Grain Interlocks.

If you ever load up any 300 Blackout subs I’ll buy some. Need them for close range back yard deer.

Now that sounds fun... but I dont know nothing about that lol

Me also.

Desperate times lol.
