250 gr Speer bullets on top of a healthy dose of IMR 4064. Gives me 2615 fps in my rifle. - dan
I used to get MOA accuracy from Max load of IMR-4320 and Speer 250gr spitzer's as well, not sure of the velocity.
Did you check reloadersnest?
I have some 4064 and some 225 sierras What Kind of load is giving you the best accuracy? Have you chronographed the load? What about primers? What is your preferred spark for those loads?
Mine always gave better accuracy with 250's. - dan
You are probably right but have loaded for several decades using lots of 250s without one. Be nice to use one with those looonger bullets like the 225Accubonds - for sure.
I like ReL15 and 250s and 225s mostly. I've also got a good factory duplication load using Rem 200gr PSP_CLs with 58grs/IMR3031 for 2751 from a 20" barrel. Here are a few tables with some of my 350RemMag load experiments.

As always be careful to reduce and work up.
Haven't tried it yet but as Stanway says above the future may be with TAC powder - comes highly recommended - especially in combo with TSX bullets.
As a guide for 225s with IMR 4064 this may help - http://stevespages.com/358_3_225.html
All excellent info thanks! impressed with all the work on the site.
I bought this rifle from a friend a model 673. Will be picking it up tomorrow looking forward to it. I have packed around a 300 RUM for a long time moose hunitng and a 3006 before that... I was considering turning it into a 338 06 but when the deal on the 350 came up I couldnt pass it up.
Would be real curius to hear how the TAC powder works. I dont see any specific load data on the ramshot website but jusdging by the claims they make on a couple calibers that I do have, I am curious!
A good friend used
63grs of ReL15
the 225Sierra
WLRM primers
2.825 COAL
for 2840MV
from his Remington model 673 Guide Rifle. That'll be a top load but he reported pressure was fine and accuracy very good every time out. Printed to the same spot as his 250gr Grand Slam loads (62/ReL15 for 2710MV - remember to reduce and work up).
You'll probably find that in your 673 with most bullets the jump to the lands will be significant. So seating to 2.825" COAL will be a given with 225s and 250s. The 673 has an almost Weatherby like freebore -like the M600s and M660s.
