Here you go.

Thank you sir the world needs more folks like you !

 

[tribb]

I would try rl16, rl17, rl26, or n550.
H4350 and rl19 would be decent alternatives as well.

I have h380 on hand and can get n540 ; n150 & ram shot big game would these be more in the burn rate area needed here? Thanks Tribb

Hey jo

Here you go.

N do you think something in the h380 to the IMR 4350 on hodgdon burn rate chart could be used I have h380 and can get n540 n150 ramshot big game.? Thank you Tribb

 

[just_jon]

H380 is where I'd start testing. If I recall, it showed some of the highest velocities. If you run out of case capacity before reaching pressure or desired velocity, it's time to move to a faster powder.

Of the ones you listed, I'd try h380 or ram shot big game. I'm afraid you will reach pressure before you get to your desired velocity.

Hey Jon I don't think the download for n555 completely came through. It refuses to open and only has 161 bytes the rest have 2.4 kb ?????

Hello Jon I measured case capacity and got 81.1 grains to top of case. Also used water to case shoulder and got 64.7 grains . How should I adjust my amount of powder?

 

[tribb]

I've gleaned what I could from the hammer information posted here. However for economic reasons I need to use some powders not listed here ! I have h1000 , rl 25 , v. n560 , IMR 4831, h4831 , and can get superformance, ramshot big game & LRT if they can be used. L. G . S. has many accurate powders on hand if one of them can be used as well. I hoping some of our members have used some of the powders listed here. Any and all help greatly appreciated i need to get these 131 s on their way! Thanks Tribb

Thanks to everyone who's helped here. It will be journey folks. I'll update the post when testing is all completed.

I was just finishing up running QL data for you. I'll make the adjustment to COAL.

What's your barrel length?

QL won't help and is a waste of time and components when dealing with Hammers

 

[ButterBean]

22" thanks for all your help



I have some h380 can get more. Also r.s. big game ; n540 ; n150 I can get ! Is this fast enough burn rate area ?

Run the H380

 

[tribb]

Run the h380

Ok B. Bean thanks

Run the H380

How do I figure a starting load with the h380
