Lil Gun or H110 for 300blk coated cast supers (123gr).. Just read Lil gun eats the co

taymag · May 19, 2016

So I bought some 123gr coated cast bullets for 300blk and was deciding whether to get Lil Gun or H110 this weekend at the gun show.

When doing a quick search I saw a guy on the castboolits forum say he loaded some Lucky13 30cal 123gr bullets and decided to change his charge a few days later before shooting and pulled the bullets and said the Lil Gun ate the coating off the bottom of the bullets...

So.. what is your favorite supersonic 300blk powder? Seems like H110 and Lil Gun is what most people use but H110 is said to have a low window of error (my measure is accurate, but once in a blue moon I get a .3 off) and now I am concerned with Lil Gun.

I like H110/W296 in 300 BLK, used mostly with lighter bullets.

I have not used Lil Gun in 300 BLK, but it did not ring the bell when I tried it in one or two other cartridges so I saw no need to try it in 300 BLK.

There are some folks that like it so hopefully some one will chime in for you.

Lil Gun has a high nitro content the reason for it running hot. It also has a history of eating forcing cones in revolvers. So with that knowledge if I had any revolvers that required a magnum powder I would choose W296/H110. I have no experience with the coated bullets so I can't make a decision if one coating is better than the other. I use W296 in my 458 SOCOM loads. There seams to be more data using Lil Gun in the SOCOM.

I have never heard of a smokeless powder eating coating off bullets but that doesn't mean it can't happen. I wouldn't worry about using Lil'Gun in rifle ammo but I wouldn't use it in revolver ammo.

I cast and powder coat my own bullets.

The mold started as a Lee 155 grain double cavity but I had the butt/base shaved to remove the gas check area and I ended up with 130 grain .311 inch. I Lee push through size.

I have used both H110 and Lt'Gun with good results. However, I prefer 2400 powder. I am using a carbine length gas system and a 16 inch barrel.

With a charge of 15.1 grains of 2400 powder, CCI 400 primers and mixed GI brass, I get an average velocity of 1960 FPS and very good accuracy. This load took a fairs sized (Missouri size deer) doe this last fall with one shot, the loading stated.

I coat with HF red and noticed that bullseye will turn the coating on the base of the bullet gummy such that it can be scratched off with your fingernail. 700x and unique seem to etch the pc a little bit and flakes will stick to the base of the bullet. H110/w296, aa1680, hp38, w231, titegroup, cfe pistol are all pc friendly powders.

First, I take anything I read on the net with a grain of salt.

That said, what difference will it make if the coating on the base is gone? As soon as the powder is ignited the coating will be gone in a puff of smoke.

You would be incorrect. Properly applied powder coat survives firing on the base of the bullet amazingly well after firing as evidenced by many projectiles I've recovered.

However I have yet to find a non gas check 30 caliber mold so the point is moot. This is because I've not been able to get a gas check bullet to shoot worth a flip as a plain base.

Bullseye and Lil' Gun are both high Nitro content powders. Lil' Gun has a rep for making guns hot. I wouldn't be surprised if it was rough on the coating.

That said, the coating obviously stays on fired bullets after seeing so many pics of fired coated bullets with the coating intact on the base.

Like Load Master's pic from a recent thread.

Bullseye and Lil' Gun are both high Nitro content powders.

Is there is list of powder nitro contents?

I stand incorrectly!

Not that I know of. I have emailed a couple of powder makers with that request and they have given Nitro %'s.

I can't find them at the moment though.
