Re: Speer Gold Dot 150 BLK

21 grains gives max pressure of 41322psi, MV=1658ft/s, 108% case fill. 105% was at 20.4 grains w/37225psi pmax, MV=1606. 8” barrel, COL=2.26”, 24.1 grains H2O case volume. Those numbers look close from memory, I will check my load data later and QL. The other powder you can try is Lovex D037.2. I u...

Re: Speer Gold Dot 150 BLK

I don’t think it has anything for lot variations, at least I haven’t seen anything. The “b factor” is a mystery and may be part of the problem. The Combustion Coefficient seems to have the greatest effect. If I bring it down to 0.8 I get reasonable numbers. Also, I don’t have the data for 1680. It ...

Re: Speer Gold Dot 150 BLK

QL will give you a basic load ladder and also highs and lows predicted for lot to lot variation of +/- 10%. What shows up in the box is in the middle. Here is an example randomly pulled of the web. Does GRT have this? If so what are the numbers? http://content.invisioncic.com/l87729/monthly_2018_08/...

Re: New to 300BLK

Its NOT reliable for subs at all..... pistol gas is king says me...... Properly configured, carbine gas is just as reliable for subs and easier to shoot for supers. There is a very narrow window where powder choice is increased with pistol gas, but that causes over gassing for supers. To say that c...

Re: Speer Gold Dot 150 BLK

It says... KABOOM! Nice MV though. https://i.imgur.com/Uylaf7C.png It only has generic D063, so maybe that’s the problem. LOL. QL shows it over 80K pressure, and a velocity just over 2300 fps. It's also listed as D063, not -02. I shoot this load in a bolt action with no signs of pressure at around ...

Re: Speer Gold Dot 150 BLK

I do not have actual data for n120 and the 150 Gold Dot.

The easiest comparable load is
18.5 N120
155.5 Berger full bore
2.245” COL
18” barrel
1900 fps.
Trim length 1.360”
Case capacity 24.1

See how that plays out

Re: 300 Blk PDW Zero

"Zero" .4" high at 25 yards.

Then confirm any other known distances you can shoot.

1.2" @ 50
-.3" @75
-4" @100

If those are correct, any other distance on the table should also be

Re: Speer Gold Dot 150 BLK

Has anyone played with Gordons Reloading Tool? It’s an free (beta) alternative to QL, but it has a pretty limited powder database. http://www.grtools.de It does have a bunch of Lovex & VV powders though, so I was looking at some 150GD loads to see how it compares to the data I could gather from thi...

Thanks for the detailed information. Are you using semi or full auto bolt carriers?
Mine are FA and buffered accordingly for pistol or carbine.
