Any LR reload info for Wby 300 mag?

I am working on a long range load for my Weatherby Mark V 300 mag using Weatherby brass (Norma I Believe), Fed 215M primers, Nosler E-tip 180 grain bullets, and IMR 7828 SSC powder. I have tried to lengthen the ogive for better accuracy and have found that shorter is better (coal 3.550) for the Weatherby freebore.
I have mounted a 5-20X 50MM Huskemaw scope and I will have a turret cut once I am able to shoot a real accurate load. Need to gather good dope before any turret cutting.
Has anyone got information can help me with creating a new load?
Thanks in advance for any information!

The nosler etips have severe accuracy problems in many rifles. The accubonds are very accurate and if you want a solid copper bullet shoot the Barnes ttsx which also have extreme accuracy. My accuracy loads with 7828 and 180 grain bullets is between 84 and 85.5 grains.

I shoot a 300wby out of a vanguard submoa model 24in barrel. I use wby brass trimmed to book min. i think its 2.815, necks are VLD chamfered and lightly necked turned. i load 168gr TTSX and 84gr IMR7828 with 215GM primers COAL is 3.560" this gives me an average vel. of 3140fps kind of a light load for a wby but is very accurate out to 850yrds is the furthest i have shot it to.

Thank you Calhunter805! I have some good information to work with now.

Still would like to hear from anyone loading for the 300 Weatherby.

I trim to factory specs and OAL is typically the longest that will feed through my action. Then I tweek it for best accuracy. The Barnes ttsx bullets shoot extremely well in wby freebore rifles and is a top choice. So are the 200 accubonds. The Bergers with the extreme ogives many times do not perform well in wby freebore rifles because their seating depth is so critical and the sweet spot can not be achieved in a freebore rifle.
