[QUOTE="brentc, post: 712248, member: 16938"] You'll have trouble getting enough Retumbo in the case to get the pressure up. If you bump up to at least a 200 grain bullet you'd be in business. You could use it, but you wouldn't obtain the performance that the 300 Wby is capable of with a 180 class bullet. Try something around the burn rate of H1000, H4831 or IMR7828 for the 180 class bullets. Retumbo is a bit slow in this application. H1000 is borderline, but it will probably get you some fantastic performance with that bullet. A good example is shown on the Hodgdon data site. It shows Retumbo as being a compressed load with a 200 grain bullet. If you must use Retumbo, try loading something in the 210-250 grain range of 308 bullets. [/QUOTE]
