Load data 

Edit:8-29-2016 added BIGGDAWG data 

https://docs.google.com/spreadsheets/d/1dEmHCV3VyJP1s-RTpxW8G68UQ-cd1cfMfP25hDdiY9A/edit?usp=drive_web

Here are final case dims and forming and loading procedures. This is the way I do it. You might have another process that you like better. I will try to add a video when I can get set up for it.

Starting with LC 5.56 once fired brass.

Resize using the mongoose size die with a .010" space between the shell holder and the die. This can be accomplished with a +.010" redding shell holder from their comp. shell holder set, or by using a shim between the die base and the top of the shell holder, or by backing off the die to create the gap (least likely to give consistent results).

Trim brass to 1.690", chamfer and de-burr and remove primer crimp if not already removed.

Try to chamber your newly formed piece of brass in your rifle.

Does it go easily into battery?

If yes then go on ahead with your loading procedure.

If no then set this case to the side and start over with a new piece of brass and reduce the space between the shell holder and the die to .008" with whichever method you selected on the first piece of brass.

Keep reducing the space between the shell holder and die and resize with a new piece of brass until your brass closes in the chamber without effort. Always be sure to keep the trim length to 1.690" which is max case length.

The reason for using a new piece of brass each time is because the brass that you just sized will not want to move with the .002" bump that you create when reducing the bump gap. It will likely try to spring back to where it was on the first sizing. Just set it to the side and start with a new piece.

Once you have your die/shell holder set so that your brass will chamber you can now go ahead and start loading whichever bullet/powder/primer combination that you want.

Once you have some loaded the neck diameters need to be checked to make sure there will be no interference in the chamber. The maximum diameter that a loaded neck can be is .269". the chamber neck is .271" so you will need .002" minimum room in order for the bullet to release cleanly from the neck and not create a high pressure situation.
The chamber reamer dims are set around LC brass as the parent and its neck thickness.  All of the LC brass that I have used clears the neck with some room to spare. Some other manufactures might not work without neck turning. Those need to be checked near the neck/shoulder jct. to be sure. I know for sure Lapua necks will need to be turned because of how thick the shoulders are on them. I also checked some TA surplus brass that was close to .269" after loading. So I turn those two manufactures brass for sure before loading them.

From all of the load data that I have seen, the published data (not data from Joe Blow off the internet) from various sources are showing max loads for 6x45 to be midrange loads for the mongoose. I have been going half way between max and min for the 6x45, start my ladders there and work up. I have been ending up around a grain or two over max listed loads for the 6x45.
As you all know, there is not a max length for it. You will have to determine where your length needs to be based on your projectile choice. We cant just load to 2.2XX" and call it good because some projectiles will be into the lands at a shorter OAL. You will need a modified case, or use some other method to determine where your projectiles hit the lands and load accordingly.

One last important thing! This is for any hand load! If you have a loaded  cartridge that does not go into battery, do not force it into battery. Something is wrong with it. set it to the side and take some measurements later. It could be a thick neck, loaded too long, jacked up case. Just don't try to force it to shoot. It can bite you!

Also, if you have a 300BLK keep it away. The short case of the BLK will go into battery if the neck tension is light or the crimp is defeated and there is enough space in the case for the bullet to set back.

Be safe!

Put some grain thru the 'goose today....  many grains of A-2200 and 70gr Nosler VG-Ts to be exact.  As per the data below, I CLEARLY hit (or exceeded) the wall before 27.0grs of powder.  Results went to hell in a hand-basket real fast after 26.5gr.

Case: LC-96 Fireformed
Primer: CCI-41
Bullet: 70gr Nosler Varmageddon Tipped
Trim: 1.675"
Powder: A-2200
OAL: 2.275"
Hits lands: 2.314"
Barrel: 18" 6 groove 1:10, mid-gas
3-rd test groups; winds 7~15mph from10:30

24.5gr Accuracy = 1.05”
MVavg: 2965 fps

25.0gr Accuracy = 1.3”
MVavg: 2998

25.5gr Accuracy = 0.20”
MVavg: 3099

26.0gr Accuracy = 0.35”
MVavg: 3132

26.5gr Accuracy = 0.55”  Primers starting to flatten
MVavg: 3162

27.0gr Accuracy = 3.4”  Primers flat & cratered 
MVavg: 3284  Failure to feed with rds 2 & 3
TOO HOT - don't go there!!

Fresh cases are LC12 and LC13, using "Custom RCBS Die" with +.006 comp shellholder, 70 Speer TNT with 26.0 grains of 1200-R, CCI 400 primers loaded to 2.26.

Rifle is 22" 1:8 4-groove. 



LC12 Fresh Brass

I ran three 5-round strings and averaged the numbers.

Avg 3135fps SD 29 (.485 group @75 yards)

  

LC13 Fresh Brass

I ran three 5-round strings and averaged the numbers.

Avg 3115fps SD 25 (.425 group @75 yards)

  
_________________________________________________

Then it got interesting.  I took my 1x fired Mongoose cases, LC12 from last range trip, loaded them with a +.008 comp shellholder, again with 26.0 grains of 1200-R but with CCI 41 primers this time.  Not as good!  I'm going to go back to the CCI400 primers on these fireformed cases, and see what happens.  I'll load a few fresh cases with CCI 41's as well so I know exactly "whom" the culprit is here.  Could be the 41's, would make sense since different primer, but I used them on firefromed cases which changes capacity so maybe the ratio threw it off as well.  We'll see next outing.  I know one thing, I'm WAY happy with the fresh case results considering my goal was just to get a good load to fireform with.  I have 200+ of then loaded now so good deal there.  Nice target load.  Now I also have about 7 or 8 other bullets and powders to try, too.  


LC12 1x (Fireformed) Brass

I ran three 5-round strings and averaged the numbers.

Avg 3140fps SD 26 (.965 group @75 yards)
