Heym 89b 450/400

[Ravensview]

Beautiful rifle, I think I’m going to have to buy a gross of keyboards as I keep ruining mine from drooling on them.

 

[Kevin Peacocke]

Kevin,
Sounds like you have the real deal in the accuracy department, congratulations.
For what it’s worth and I know you fretted over it but the effort and cost you went through to get the dot sight and mount exactly right was well worth it. looks really good as well !!!

JP

Thank you JP.

 

[Kevin Peacocke]

I have to second that. I am not a fan of red dots on doubles. Too often they stick up in the air like some weird appendage. Yours is mounted extremely well, and does not detract from the aesthetics at all. Well done!

Thanks WAB.

 

[Kevin Peacocke]

Heym does a good job on the mount and the cutout at the rib for the red dots.

They do Tanks, but I just found the mount too high for my cheek weld.

 

[Troubleshooter]

Please can anyone let me know actual velocity of factory ammo even if it isn't fired from a Heym?

Sorry I'm late to the party, but six Hornady factory DGX fired from my 24" barrelled Jeffery boxlock averaged 1998 fps, with a high of 2033 and a low of 1967. They had not yet achieved convergence at 50m distance.

But it sounds like you have already found your best handload.

Thank you Troubleshooter, yes I think the sweet spot for me is 2015fps.

Kevin that's a beautiful accurate rifle.

Kevin I have to say, the proportions 'c that frame on your 450/400 make the 89B .. the Gross Box on the 500 throws me off a bit. Just my opinion. Sorry has no bearing on the thread or the 89, with all due respect.

Sorry for the late reply Kevin, I've only just noticed your question. My Merkel 140AE 450-400 3" with 60 cm barrel (approx. 23.5") shooting Hornady factory loads averages between 2000 fps ( at 5°c) and 2080 fps. (at 30°C) AND there is a consistent difference of about 20 fps between the right and left barrels. Shoots good consistent groups from both barrels despite that difference in velocity on hot or cold days.
Glad you found a load that regulates well. Happy Hunting!

I see Hornady quotes 2050 fps out of a 24" test barrel. So what might be reasonable out of my 26" Heym barrel, 2080fps?

Congrats on having a 26" barrel. I think you're spot on, 30fps every two inches is the rubric I always use.

My 89B chronos at 2035 to 2045 at 5,500 ft of elevation on sticks at the range in CO.

 

[Green Chile]

Excellent. That’s the Heym mount?

 

[Kevin Peacocke]

Thanks buffalo,

 

[Frederik]

Kevin, love that Heym of yours nice piece of wood as well.
Regulated for 75m is superb!!!
Now to stock up on powder and bullets while you have the load and there is stock.

 

[Safariswestcam]

Love that rifle and almost positive I have settled on the caliber as the best suited, well rounded for a double rifle that will see far more plains game annually than buffalo or elephant. Called Chris today to talk about timing... seeing yours Kevin only fuels the fire!

 

[Rare Breed]

Can’t go wrong with that for sure!
