243 with H4350…?

rankin76 · Aug 15, 2024

Has anyone loaded 85 grain Game Kings with H4350…? Looking for a starting charge to a maximum. Having trouble finding data.

The reason I'm asking is because I'm very low on IMR 4064 and don't feel like spending a $100 for a pound of powder shipped.

Thanks

QL shows 43.5 as max. Back of 10% and give it a go. As always, proceed at your own risk.

If you go to the Hodgen website you should be able to get data. I have a bunch on my computer at home and can check later.

Best I could do at the moment

I have always used 43.0 grains of H4350 with 85-87 bullets in my .243's. I'm guessing pressures are close to 60K psi.

As usual, work up to load startings at various manual specs.

Thanks for the responses, the Hogden load looks on the low end, I have the Sierra book and it doesn't show H4350. But the QL load at max 43.5 grains sounds like it's in the ball park. That was close to what I loaded with the 90 grain ELDX. Which my 243 absolutely hated.

I use IMR4350 in my 243's. So you should be able to find a load with H4350

This should help you out. You're right in the middle. I will say that my best load for that bullet was with sta-ball 6.5. However I got a .607 5-5shot group average with 42.5 gr. of H4350 and it was safe in MY gun. Velocity was 2822 SD 14.8.

Yes. Good combo to see if your rifle responds well to it.

In Rem 700s, I shot a load of 44.5g of IMr 4831 with 85s, faster than my load of 37-38g of IMR 4064.

I've loaded around 41 grains of H4350 behind the Sierra 85 grain BTHP and found it deadly on whitetail deer. Also excellent accuracy in my Rem 700.

the load I used to have with this bullet and IMR 4064 had taken several deer for my brother. Now I'm hoping to do the same for my nephew. It's crazy how expensive powder is now especially with shipping!! I have several pounds of H4350 so I'm thinking I'll be able to get something running for him.

I worked up to 43.6 grains with the 90 grain ELDX at just under 3100 fps with no pressure signs, so I'm sure the 85 grain Game King will be somewhere close to that.
