I haven't loaded the Nosler 220's, but have been loading some 220 grain Sierra Match Kings.  Out of a 10.5" barrel, I was getting 1044 fps with 11.3 grains, 1075 fps with 11.5 grains, and 1086 fps with 11.7 grains.  I wouldn't deer hunt with this load, I was mainly coming up with loads to shoot through my suppressor when I eventually get approved.  With the 11.7 grain load, energy was only about 580 feet/lbs.

(ETA: This was with 1680)

Heads up on case making.   Make sure you clean any fine brass cuttings (powder) out of cases before

loading.  I noticed the "gold dust" but didn't think too much about it.  My gun, 16" barrel with pistol gas,

threw fired cases about 10-15 feet at 5 o'clock until it quit working.  Finally found the problem causing it

to be under gassed to the point it would not eject cases.  The carrier key was packed about half the

length of the key with brass powder and carbon. It was like concrete. Had to drill it out.


I have to admit I really "lit it up" at the range on El Presidente when it quit working.

That's interesting. I might buy some of those bullets and try them out. I'm about 100fps slower with 125 grain Sierra's and the same powder charge, out of a 10.5" barrel. Thanks for posting your results.

I'm finally getting my 220 grain Nosler Ballistic Tip Hunting bullets tonight.  I'm going to work up a subsonic deer hunting load with CFEBLK or Lilgun in a 9" suppressed barrel.
Judging by the following data which was gathered with a 16" barrel, I'm going to start at Hodgdon's max loads and work up to 1060fps or pressure signs (whichever comes first).  Sound reasonable?

I was loading long, fat bullets (MBC 245gr)
And had issues.
Everything was fine and then a Bullet would only seat about a 1/4 " and everything would go crazy. And crimp the crap out of the case.
 Turns out all the moving parts inside the seating die, would slide far enough apart, from the long bullet, to not support eachother. Everything eat its self and went south fro there.
Hornady replaced everything and I went with a skinnier bullet up near the tip, so the two parts are slid into eachother to prevent this.

My point is it started with a ring in the bullet.

I'm sure it's in this thread...someplace.

The above post was for the pic....i guess
I quoted the wrong post, my above reply was for you.
Check the two parts in the die.
Mine locked up and would push the crimp ring down with the setter.......very hard to explane

i looked in this thread and can't find it in the 300 blk thread, must be in the normal reloading forum

Can anyone suggest a starting point for the following combo? My goal is to make a supersonic plinking round for a 9" pistol gas AR.

I'll be using 150gr Hornady fmj seated to 2.080, A1680, cci 41, and Hornady casings. Accurate's data states 19.4 grains with a 150gr fmj as a minimum.

The thing is, the powder seems very high in the case at 19.4 grains. As I increase the powder charge by .3 grains the OAL grows with each increment and resistance on the lever increases slightly. I don't hear any crunching but this tells me they're probably already compressed at 19.4. OAL was longer at 19.4 than with the dummy round I made while adjusting the seating die.

I don't feel safe firing any of these and thought I'd check in with you all first.

The accurate data I have doesn't list the hornady bullet but a sierra 150 bt at 2.15 col. The Hornady 9th lists the 150 gr fmj at 2.220 col with 15.4 as a starting load. While the accurate load tables show a compressed load your col seems a bit short.

15.4 sounds more appropriate. But the OAL was determined using the .25 measurement on the ogive at the mag rib method. 2.220 may be ok for a bolt action but is way too long for an AR magazine. I know Hornady is always conservative with their load data but that is a HUGE difference in powder charges.

So if I'm understanding this correctly you had the same issue? Did you do any testing or did you just decide to scrap it and move on to the lilgun?

I have lilgun too but wanted to try 1680 because I have a lot of it.

I'd save that 1680 for heavy subsonic rounds like 200g and above.  It's a great powder for that.  There are much better choices for supers as already stated by others.

I already use it for subs but I stocked up a couple of years ago and now have more than I'll ever need. I use H110 for 110 and 125 grain supers already. Just thought I'd put it to use with all the 150gr fmj I have for .308 loads. But if it's that terrible of a combo then I won't bother.

I'm getting horrible accuracy from my sub loads, I'm talking 12 moa bad .

Bullets: NOE 247gr cast from straight wheel weights, powder coated and sized to .309".

Cases: Once fired factory brass (not converted).

Case prep:

• Resized so the shoulder is pushed back .002" from a fire formed case.

• Trimmed to 1.355" if needed, all pieces are chamfered and deburred.

• Primer pockets are uniformed.

• Necks are expanded with a NOE .312" expander ball.

Load, seating, crimp: 11gr of H4198 for ~1040 FPS. Bullets are seated to the top driving band and crimped with a Lee FCD just enough to remove any bell left from the expander.

I'm using a Ballistic Advantage 8" 1/8 twist pistol gas barrel that slugs to .307" which should be perfect. The bullets make a strange "wizzing" sound when fired but aren't keyholing and there's no leading in the barrel. This has been really frustrating and I'm about ready to call it quits. Does anyone have any ideas as to why I'm this accuracy issue?

Using your terminology I'm doing a 3/4 crimp.

Any idea why the bullets would make a "wizzing" shound when fired?

Look down on FCD, notice the 4 slots in the collet.

Adjust crimp so that gap closes half way, and you have what I call a normal crimp.

Close gap 1/4 way= light crimp.

Close gap completely= heavy crimp.

These are my terms/method, good luck.


Eta, one more thing. What are you using to expand the necks of your cases? 

I use a Lyman "M" die.  Lyman M die

If you scrape any of the bullet when you seat it, accuracy will be terrible.

Why does it say that expander die is only for those 3 calibers? Seems kind of odd... I may need to pick one of these up as well, I'd like to put a very slight belling on my cases when I start loading some powdercoated bullets

I think Dillon recommends the 7.62x39 powder die to bell/expand the case mouth. I will have to double check. But I think that's what I use. Call Dillon and they will tell you what works. I use it for the cast bullets I load and have not had any problems.

I would first convert the cases, THEN worry about loading them.  

A lot of people seem to do well forming cases with Dillon's sizer and trim die, but make sure you properly expand the necks or you'll have problems.

I form my cases the old fashioned way: I chop them to length, anneal them, size them, then trim them.  I personally feel that annealing after shortening but before forming gives me more consistent necks.
