Follow up - Malcolm Seller's very prompt and pleasant reply to my inquiry about their bullets:

Dear Mehul

The bullets are produced by BES Bullets. We only market in the UK but would send to the USA. We take dollar cheque's.

The 215 grain bullets are solids and reproduce the original .303 Mk 6 bullet. They are meant for target shooting.

They do break up readily, they have an outer jacket of copper, a hardened lead core, and whilst would suffice for small game I would not recommend them for anything which requires deep penetration.

The postal costs to the USA for lead are high and if you visit the UK or have relatives going over then the bullets are not regulated and you require no license to purchase them here and leave the UK with them.

Components such as cases and bullets which are solid are not regulated.

I do not know about USA import rules. I have sent some by post to a buyer in the US without difficulty the cost was about Ł7 per hundred sterling postage. We charge Ł17-50 per 50 for the bullets.

Regards

Malcolm Seller

Hope this helps anyone interested in buying them over here. I plan on ordering some.

Good hunting!
