I just used an .30 cal collar on an OAL gauge to measure the bump. I don't bother any more.

But yeah, just adjust the die down an 1/8 of a turn until you achieve the desired result. All that you...

Pretty sure 10 thou was all I needed as well but got a bit more in case I ever needed it.

Change of brass brands etc.

What ever gives you a bump with the feeler gauge.

I got 15 thou off mine iirc.
Adjusted until I got the bump I wanted and locked her solid. Works a treat now😆

Just a suggestion, but get your FL die ground a bit so you can bump the shoulder. Body die won't do the shoulder.
If you are worried about case head expansion (I wouldn't worry about a little more...

I have a forster press so no choice in shell holder as such and had similar issues with my AI

I had to get my redding FL die ground as it didn't bump the shoulder at all in my press.
So now all I...

Maybe 150-200 fps more depending on barrel and action. Not (real world) worth it Imo.
I was bored and wanted a project so had one done ages ago.
It turned out primo but there was a lot of learning...

Looks bloody good. Rem brass is probably a good start as it is softer. Also looks to have a sharper shoulder than any of my first time, formed brass.

I might have to get one😆

Being the mong I am, I would have completely sussed it by looking at it and then proceeded to destroy 30 cases before I bothered reading the instructions. 😆

40° shoulder?

My unformed brass is on its way😆

My body die will still bring them to chamber after 8 or so firings but they won't hold a primer well enough.

No sorry to confuse.
I am a dinosaur and still use imperial when it comes to reloading.😆
Also case head expansion is the best way to indicate max pressure in an Ackley Imo.

You don't want to...

I would measure the case head with a mic. Anything over .0005 over from a new case I would keep an eye on.

In saying that I could get away with 46grns of RL17 in my rifle.
I stopped using it...

Load so they only require a neck size until the 4-5th go and you will be right. If ya have to bump the shoulder or body size after firing one formed load you are getting up there.
3000 with a 140 is...

I use heaps more AS 30N than that.😆

43 grns of 2209.
Pretty sure it can handle another grain at least as the shoulders only formed about the same as I can get without projectiles.

Had a play with my Ackley and FF some cases with projectiles. I have not even tried it with this barrel before so was pleasantly surprised how well it went.

129 gr interlock hard into the lands...

I am surprised you used those words in a sentence regarding a .243😆

Sent from my SM-G900F using Tapatalk

Is that why it only reads pedestrian .243 speeds now?

Sent from my SM-G900F using Tapatalk

Mine sits in the same place if not a tad closer.

Sent from my SM-G900F using Tapatalk

Looking good.
I use a bit more powder to achieve similar velocities but I coat my projectiles.

Sent from my SM-G900F using Tapatalk

Try mag primers with different powders behind the LRAB.
You might get them to shoot.

Do what works best. Remembering an improved shouldered case will not show pressure signs like a bottle neck.

I only neck size until they get a tadd stiff to chamber an empty. Usually 4-5 goes...

True.

Have had a .260 imp for a while now and think I have my forming and loads as good as I can get them.

Have formed Lapua, Rem, Norma and Nosler .260 brass.
Rem and Nosler work best in my rifle.
