Home Forums Hunting & Shooting Custom Rifles & Wildcats Where do you guys get your .243AI dies from?

That's what I'd thought as well, but I've annealed them pretty well. Might just be time to trash that brass

I assume that you guys that use the LCD's are having to bump shoulders back after a few firings?

Jordan,
For my Montana 243AI I bought the Redding Type S neck bushing die set for mine, then added the VLD micrometer seater. Works well so far, just started loading my FF loads last night.
Hope to shoot it this weekend after I kill a gobbler Sat morn....

I haven't had to touch the shoulders yet, but may need to in another 1-2 firings.

Nor have I yet in 5-7 firings.

I bought 50 Nosler brass when I built my .280AI... and used them for 364 fired rounds (when I sold the rifle, along with 44 of the brass)... and never owned a die set for it, all I used was the 7mm Rem. LCD set.

You do need to anneal after every 4-6 firings depending on your chamber... and I'll occasionally lose a piece of brass to case head size, but I don't remember having to bump shoulders.

This is the Redding set I purchased:

Just got the Redding set this week that I ordered from Midway. They had plenty in stock a few days ago - I'd buy them while they do. Seems like they run out pretty quick.

Bumping this thread to see what you guys like. Just picked up my first AI gun in 243ai.

This should make some interesting reading for you...

If you are using a single stage press and lubing brass, pretty hard to beat the Redding FL type S sizer and comp. seater.

Progressive press and the Type S neck die is slick with a nitrided bushing. I only lube when bumping shoulders with a body die. Most aren't doing it like this admittedly, but man is it nice.

Using a single stage RCBS Rock Chucker.

Considering doing the Lee Collet for neck size/deprime, then need something for bullet seating. Can I use my RCBS 243 bullet seating die to seat bullets in AI cases? So much to learn...

This is pretty standard for this rifle, with factory RemV barrel punched AI and recrowned, thrown powder charges, and LCD/Redding standard bullet seater. I've been very happy with the die setup. I PFLR with the Redding FL die when chambering becomes tight.

I have a .243AI on a Rem700 action, 22" bbl, and shoot the 85g TSXs. I can't recall the load data right now, but I do know I spit them out at 3,450 FPS w/out flattening primers or hitting excessive pressure ranges. I think I'm right on the edge of getting to that point, but it's a safe load, and is super-accurate.

I'd be surprised if you can't easily get 3,500 FPS out of the 80g TSX and have great accuracy at the same time.

First load...3485fps

+1 for Lee Collet dies.

Miss my Nesika 243ai.

Can you guys give me your fire form loads please? I am getting my 243 AI ready for some more soon. I am using Lapua brass, RL-17, 87gr V-max and a CCI 200. I also use moly.

I also have other powders and 105's if you have good results with a different combination.

Thank you!

Just use a mid to max published load for the SAAMI .243 and rock on. I use 37-40gr IMR4350 with the 87gr V-Max and Lap brass. I imagine your charge of R17 will be similar.

A good starting place for loads for 243 AI
