6.5 - 139gr Lapua Scenar for Varmint hunting

[Fore300]

Wondering if anyone has done any Varmint hunting with a 139 Lapua Scenar? Will this bullet expand enough to quickly dispatch a Coyote etc?

I typically use my 22-250 but have built a long range rifle in a 260 and was wondering if using my target rounds would work on Coyotes

Thanks for your input
