[QUOTE="IdahoCTD, post: 939619, member: 13110"] It seems like a slightly slower powder would yield even better velocity. That was the case with my .375 RUM anyway. A stepped throat in this might be quite interesting and yield some velocity gain without the worry of barrel life. You might see 2900+fps with the 320's and over 3000fps with the 300's. I may just order a reamer based on my 30-338 Norma Imp instead as my shoulder dimension is larger and get a stepped throater to try. I have a Lawton 32" barrel that I bet would yield another 100fps over what your seeing. It would probably put me dang near 375-338 Lapua Imp. velocity. [/QUOTE]
