I searched through related threads last night & couldn't find for the life of me Heym's "Frame Chart" for the 88B someone had posted ..
It showed the 88 in .577 available for the "Large Frame/up to .577" & the "Jumbo Frame/to also accommodate the .600"

Simply, could Heym build an 577 88 in a Boxlock? .. without stepping up to the Jumbo/Sidelock?
Thank You!

I’m sure Chris will chime in with the definitive answer. But I’m pretty sure when I talked to him you could get the Gross box action in 470,500, and 577 in either the 88B or the 89B action that is there largest box lock action before going to the jumbo action. I do know the 89 B can defiantly be had in the 577 as I was going to order one once my 450/400 finishes up.
 
I think we have a group from Heym hunting with us in June, I hope they bring some nice doubles with them !
 
I’ve personally shot a Heym 88 in 577. It had a case colored frame, and was definitely not one of the jumbo actions. It weighed 13 pounds with two cartridges in the chamber, so that places it in the “large box” category. That being said, Chris Sells would have to chime in if you can still order a new 88 in 577.
 
My friend, Tanzanian white hunter Mark Sullivan (of Nitro Express Safaris) currently owns and uses a Heym Model 88B boxlock ejector in .577 Nitro Express as his backup rifle of choice. He bought it secondhand from a client.
 
Beautiful machines & great feedback, thank you.
Really curious if that indeed can be the case, an 88B, "Large" Boxlock in 577.

What happened to his 577 Heym sidelock he had built for him?
 
Thank you @frog stealer & (@Hunter-Habib ): "I recall you mentioning that"

That was undoubtedly the finest machine I've ever seen, imo.
It just prompted the question if an 88 can be built in 577 without the extraordinary start cost of the Jumbo/Sidelock? .. or going the 89 route.

@Lowdi .. That is a beautiful 88 above.
 
Surely that can’t be the reason??
From Mark:
"Hi Habib, always good to hear from you. In this video you will see Mark Egger using my sidelock.577 Heym. It’s now his. He bought it from me. I’m using a .577 Heym boxlock that I bought from a client who had upgraded to a .577 Holland. I made many upgrades to both Heyms. The boxlock I still have. It weighs 12 1/2 pounds."

"I gave Mark Egger the choice of both rifles. He picked the sidelock. With that said, boxlocks are fabulous guns. Of the two Heyms I actually prefer the boxlock".

Just wanted to say thanks for the excellent customer service. Ordered some 9.3x62 brass and the delivery was a little short. An email through your website Contact Us link was replied to the next day with the tracking info for the correction. Good pricing coupled with great customer service will see returning customers every time. Thanks again!
