[velvetant]

Thank you very much

 

[Dwh7271]

You are certainly welcome!

 

[desertcj]

H4350 looks like a screamer! I wonder what might be possible with Superformance or RL17?!

 

[velvetant]

Those QL velocities are a bit slow, I know for a fact my rifle shoots a 70NBT@3750 with 48gr H4350.
I really can't see the Varmageddon bullets that much slower.
But it does give me load data to try and I can chrono later if they show promise.
I have some test loads ready and hope to get out in a day or two

 

[IdahoCTD]

I'm with velvetant. I shoot 105's 3250fps in my 243AI so only 300fps faster with a 70gr seems rather slow.

 

[Dwh7271]

V,
If you run a few across the chrono, give me case capacity etc, I can give you better numbers based on what you're actually experiencing.

Sorry they seem low, though.

 

[velvetant]

No apologies necessary, QL is another great tool for reloaders.
So many variables with the program and all the different rifles.
The charge weights look right for H4350 from my loading notes with the 70 NBT.
I just double checked my h2o capacity and it's 56.5gr not 57.5gr I posted earlier.
Not sure when I can get chrono numbers. My shooting time is extremely limited, hence why I'm not here much like I used to be.
