450 grain 425 Westley Richards

[DILLGAF]

Hello,

I am in the process of building a 425 Westley Richards rifle. I intend to have some 450 grain lead flat nose bullets made and order some of the Hawk Bullets 450 grain bullets. The problem is there is no mention whatsoever of that bullet grain weight/cartridge combo anywhere. Hawk makes bullets in that grain weight so I imagine someone has loaded for them. I was wondering if anyone has loaded those bullets, and if so, any help on load data would be greatly appreciated. Thank you in advance.

The 425WR shoots a std 410gr bullet, which is pretty much all I have found for mine.
I am unfortunately not able to assist with any data on a 450gr bullet. I am however very curious, because with the COAL sensitivity of the 425WR and the limited case capacity, I am battling to imagine where the extra weight goes when the case is full………

Keep us posted, please.
