300 blk dies

[culater]

Just like to know what dies you guy are using. I have upper with a 1-6 twist coming next week. Looking to use it for hunting and subing long range for fun. I understand that the 300 can be l little hard to bump the very short shoulder. Just need some insight Thanks

I have the cheap hornady kit that I added a micromenter to, didn’t really help as the micrometer is still maxed out. The sizer is fine, the seater is crap for me. It’s a generic 30 cal seater and I only have like 1.5 threads of engagement in the lock ring while set up on my Co-Ax before it tries to crimp and smashes the shoulder in. Maybe in a more traditional press it would be better... but I’ve been watching for a Redding to go on sale.

What powder do you use?

I bought a set of RCBS AR series for dies. Have yet to use them. I plan on working on a hunting load with 110gr Barnes Tac-TX and everywhere I've seen recommended Lil Gun powder wise for that bullet.

I ise the hornady die set as well. Works just fine for everything i use my suppressed sbr for.. does everything from up close plinking to 400 yard steel shooting.

I use the Forster ultra 2 die set.
Probably not needed, but the micrometer seater makes it easier seating different bullets during load development.

Running every thing same as spife 7980.
On a lee press.
Seems the hornady seater is very touchy on getting a crimp with 2.1 coal
For the 220g rnfb

Any input to setting the hornady seater would be apreceated, I want a small amount of crimp.

Been using Redding 30-221 deluxe Die set for long time, works great for all 3 cartridges, 30-221, .30 whisper and .30 BLK . Best crimper, is the Lee collet crimp Die for subsonic loads .

Forgot to add i do all my crimping on 300blk with a Lee fcd.. i chose to do it on a different step than seating.

With the Barnes 110 gr. I'm loading 20 grains of H110 and it shoots lights out.

I'm using the Forster die set with Micro seater. and does well with shoulder bump for my bolt gun.

 

[Snuby642]

Thanks, have the lee fc die en rout, slow boat evidently.
I suppose I will have to check loads from the start since it will change pressure?

 

[Snuby642]

So I got the lee fcd, my 220 cfeblk loads tightened up over 3/8 inch first try.
Will soon test crimp amounts, have not figured out a way to measure it?

For Subsonic Crimp .. It does not take as much ( handle push weight ) as one would think with the Lee Collet crimp die . ( same as blk5.3 said above ) .. I also do crimp separate step after seating .

I have a heavy metal lever handle on the single press . take it easy at 1st . just do 'very light' press push on your lever, and it will crimp . You can also take a look at it next to a non-crimp seated bullet with magnifying glass to make a visual . Or just check with a kinetic puller, take a look at the bullet jacket after you pop it out of brass .
also Nice thing about the Lee Collet is that you can get good feel also for the Brass Necks when you get a odd one with slightly thin or thick wall on Neck of Brass .

Yes they vary, guess I will have to sort brass to get it consistant
