H110 loads needed.

[Mike Bell]

I need some super sonic .300 WTF, H110 loads with these bullets if you want to share Help a brother out so I can get shooting.

16" TP555 Barrel, pistol port with TP555 adjustable gas block.

Hornady 150gr. Interlock

Barnes 130gr. TTSX

Hornady 165 gr. SP (old stuff I got left over from 15 years ago, only have about 25 bullets)

[N310toN170]

H110 can be terribly temp sensitive but this time of year should be good; careful using these same rounds come summer!

I agree with N310,
I have reloaded and shot the 300 -221 from a custom bolt setup for the past 3 or 4 years and have found H110 too erratic for my needs. I pretty much have gone to Lil'Gun for my subsonic needs.

Now, this is what MY gun likes, YMMV,
I have found that 8.8gr LilGun under a 308 Lehigh/20gr. Berger .17, CCI small rifle primer and trimmed 221 brass produces just about 1060fps all day long, no more bouncing up above speed of sound as temps climb or barrel heats up and transfers to round sitting in chamber for a few extra minutes.

H110 is also positionally sensitive, so be sure the powder is all at the bottom of the case (or close) when you ignite it.

I used H110 for about 6 months before scrapping it, too many problems.

Good luck.

Well I guess I'll just shoot up what I can for now.

I will be shooting supersonic so... I guess Ill find another powder.

Aa#9 is my go to for subs, h110 is erratic on subs but never used it on supersonics.

Hodgons reloading data center has blacout data for supersonics with h110
