.300 BLK load thread

[CP]

I’m finding conflicting data on loading for 125g bullets in the BLK.  Hodgdon data gives a max load @ 21.0g of Lil’Gun.  Nolser data gives a max load of 18.0g Lil’Gun for the same bullet.  Hornady lists 19.5g max for their 125g SST.

I don’t know who to believe.

I’ve loaded the 125g Hornady SST to 18.5g Lil’Gun without any pressure signs.  It’s plenty accurate for a hunting load and shoots very flat out to 225y.  I’m not sure if I should try pushing it any further or not.

Anyone else loading the .300 BLK?

I shoot the 110gr Barnes Tac-X
20.2gr H110
CCI 400
2.250

Federal mil-spec brass.

I found once fired brass trimmed, and sized to .300 Black Out. Polished and gauged. Just load and shoot for $110.00 per 1000 Shipped.

Have you taken an animal with that load?

I've run H110, with 125gr Noslers, and 130 Speer flatpoints for a while now.   130's with 17.0-17.5gr H110, work really well on deer, and have a text book mushroom at blackout speeds.

I just built a AR to try the chambering. I don't care for the cartridge at all, with the acception of subsonic loads and a suppressors.

For taking big game I would rather shoot a AR chambered in 6x45, 25x45, .243 LBC, 6.5 Grendel etc.

I've taken 2 deer with the 130gr TTSX out of a 10" contender in 30 Herrett which gives velocities about 150fps slower than the 300 blk from a 16" rifle. They were both small deer at under 100 yards but both were DRT with good shots. The 300 BLK isn't a power house but it's not terrible if you're smart about your shots.

When I had a 10" 300 whisper I ran the 125 NBT and H110 good results at around 1700 fps.

Have you tried Lil'Gun with these bullets?  Book data shows higher velocities at lower pressures than H110.  I've tried both and don't see a difference but I don't have a chronograph.   I need to breakdown and buy one.

I like the 130g Speer but I have feed issues with it.

I haven't tried Lil Gun, in my blackout, I really was chasing accuracy more than velocity, and H110 gave me everything I was looking for.  My blackout is a Rem 700, and it was hit and miss with the 130's until I got the seating depth just right, now it feeds smooth.  The same 130 flat points feed great in Ruger American Ranch rifles as well.  I was getting around 2000 fps with the 130's.  I don't have my notes on hand to tell you exactly.  Accuracy was sub moa in my gun <3/4" 100 yards. 

Completely off topic, but I'm really wanting to shoot the new ruger American ranch 450 bushmaster.   It looks like it would be a stellar brush gun.

I tried lil gun and h110. I run h110 with all my blackout loads super and sub sonics. I run the 125g ballistic tip for my super. Have shot a few coyotes with them and I would not have a problem shooting a deer with one at a reasonable range.

Some range time with the Ruger Ranch Rifle.  It is only a 16” carbine but I’m still not particularly impressed with any of these.

Do you mean a Ruger Ranch rifle? As in, a Mini-14? If so, you're doing pretty well with it, they are not a target rifle. I would think that's about as good as you could expect with one of those; it's not the caliber, it's the rifle.

Worked up to 20.0g of L'Gun today with a Chrono.  L'Gun seems to work better when compressed.

This bullet is a mess.
