VLDs Don’t Fit in Ammo Case

[General RE LEE]

Ok so this is random but I loaded up some 168 grain Berger VLDs in my 7mm STW. I did the various seating depths per Berger's instructions and the top won't close unless I force it on my MTM ammo case. It lists the 7mm STW as a compatible cartridge for the box but I'm assuming the long VLDs seating far out are well beyond SAAMI COAL for the 7mm STW.

Will having some pressure on the bullet tips from the plastic box mess up the seating depth or tips?

Use MTM J-20 LLD; it is good for 3.84" OAL unless yours is longer.

Which MTM box do you have?
My STW rounds fit in my MTM 100MAG with 168g ABLR, but my loads are 3.7".

Cheers.

I use the second one for 30-378 loaded over 4".
I know they are out of stock now but it would be an option when available.

MTM pretty much it covered.

BTW - Graf's has the MTM J20 LLD in stock and prob best price with 10% off if buying 6 or more. This thread just got me to grab a couple for upcoming .270 Win build that will have really long COAL that will be ok in the J20-LLD boxes.

Perhaps a taller case would help.

MTM J-20 LLD

I got the ELLD 50 which is good for 3.85 COAL.

Are you saying you got ELLD 50 instead of MTM J-20 LLD, or are you saying your 7MM STW SAAMI load will not fit the ELLD 50?

I got the ELLD 50. SAAMI 7mm STW loads will fit but VLDs loaded long are tight and pushing on the lid.

 

[General RE LEE]

It's close and pushes on top.

So, what exactly is your COAL.

That is definitely beyond SAAMI COAL. My Berger reloading manual shows 3.650" COAL for the 168 VLD on 7MM STW. How did you derive to your COAL or CBTO (https://bergerbullets.com/wp-content/uploads/2013/03/COAL.pdf)? Have you shot them yet? Repeater or single load?

Feenix, General RE Lee has a unique long throated STW chamber, something on the order of 220" long.
I found this quite puzzling as my own reamer has 'zero throat' and the leade in total is only .076" from memory.

Would need a 4" box to be able to seat anywhere near the rifling with a .220" long throat.

Cheers.
