REDDING Comp Seat Die

[Ballistic Artist]

Hey all,
Im running a Redding comp seat die with Remington brass cases that have gone through a Redding type S FL size die. Bumping shoulder back .003". Also, .003" neck tension. Im seating 208gr AMAX bullets. For some reason, every now and then, I am having bullets seating .0025" too deep. Anyone had this problem before? Thanks.

Also, Anyone heard anything about The AMAX shortage?? 208's are non existent.

Where are you taking your measurements from?

Bullets can easily vary .0025 in length. Im not sure about the AMAX length variation, but that can be seen with a regular tipped bullet. Check with an ogive comparator, and make sure there are no brass or copper shavings inside the die.

Re: REDDING Comp Seat Die

IF the nylon tip is being impacted while seating, it could throw off the seating depth. I would consider .001 being statistically insignificant, but .0025 is too much.

And yes, I have seen that all AMAX bullets have gone into hibernation!

Im using a Sinclair comparitor with 30 cal insert.

I use the same seating die and have not seen any variation when measuring from base of cartridge to the ogive.

MidwayUSA had 208 amax's in stock a few days ago, picked up a few boxes for the 300wm.

Re: REDDING Comp Seat Die

I quit using COAL measurement and now measure base to ogive for exactly that reason. I only use COAL to fit rounds into a magazine. Although Lapua bullets are very consistent, they still have variation with bullet tips.

Ballitic,
You can measure the ogive of your bullets alone with the comparator, see if there's a diff.
Or you might need the vld seater stem for your die, it costs 12 bucks or so if you look around.
My 6,5 die worked, but had to buy one for 7mm. A freind just bought the same 6.5 dies and his seater is cutting into the bullet.
A thought.

Re: REDDING Comp Seat Die

Differing degrees of brass hardness will result in inconsistent seating depth.

Anneal your brass.

The cases I were using were once fired. Do they have to be annealed after each loading??

Re: REDDING Comp Seat Die

I had issues with the Redding seater die. Quite a few comments on it here if you search, the stem is soft steel and can swell. Foreter dies have a hardened seating stem in them.

Take your dies apart and see if the seating stem is swelled and hanging up. If it is, you can probably polish it on a rock while chucked up in a drill but you could be inducing runout into the equation.

I didn't get any help from Redding when I contacted them, they know it's an issue and the recommendation to not use it with a progressive press is in the paperwork that comes with the dies.

Not trying to hijack--but are folks using the std or VLD redding seater with 210/208 SMK and Amax?

Thanks,

Standard for 208 AMAX. works fine.

Measure your bullets base to ogive and make sure there are not two different lengths of bullets in your box.

You can do it with your caliper and comparator or get a bullet sorting tool from Sinclair that will speed up the process.
