Good 300 RUM reloads needed

[noneck180]

I have most powders, just looking for some places to start. I have the manuals but they are so off in most cases, all they do is waste powder in most cases. I don't want new reloaders to do the same as me..I am shooting a Sendero 300 RUM..
I have 180 gr TSX
200 gr accunbond
200 gr Barnes LRX

So please no reloads with other bullets..

200g AB over 93.5 Retumbo = .8" moa @ 400yds
200g AB over 90.75 Retumbo = .7" moa @ 200yds (haven't had a chance to get it out to 400yds )

The Sendero should shoot a little tighter . I tried RL25 with decent results but needs more testing.

Just went to prime some new brass, they won't fit in my Lee autoprime. Wonder if I could just take a little metal off the mouth of the autoprime to get them to fit.

Mine likes the 200gr accubond ahead of 95.5gr retumbo, cci 250 primer. In remington brass, a little too hot for the softer nosler brass. I would start around 91gr and work up.

That is exactly what I had to do to get them to fit in my Autoprime. Just hogged it out a little bit with the die grinder.

Sorry, I don't have any loads for the bullets you listed though.
