H1000 in a 20” 243?

[houser52]

Used in a 20”, 1:8, Tikka 243, 108gr. ELD-M, Starline LRP, CCI 200.

Think it’s too slow for a 20” with a lot of unburned powder, high ES, accuracy?

Worth trying or try something else?

H1000 is the ticket in my 22" tikka with 108 eldm's. Picked up almost 100fps and better accuracy from h4350. Give it a try.

Try it and see. We used H1000 with a 100 bullet in a 20 inch barrel.

What charge weight did you start at?

 

[Karl B]

Can't remember where I started. Probably 44 or 45 grains.

Interesting. I need to try some H1000 I guess. I use H4350 and N555 in my 24” 6 creed with 108 grain bullets. Extra speed would be sweet

47 is where I landed as well with lapua brass.

I have been loading 44 grains of H4831sc and only averaging 2700 fps but accuracy is good out to 400 yards. If I increase the charge by much I start to see pressure signs and accuracy goes down hill.

I’ll give H1000 a try and maybe it will give me a little more fps and still be as accurate.

Are you guys using standard primers or magnum with H1000?
