Just got done shooting some 200 grain Barnes TSX in my Win 70 classic 26" barrel.

IMR 7828 71 grains 2766
72 grains 2790 (case is full)


Retumbo 75 gr 2861 (case is full)
80 gr 3006 (way over max in my rifle, brass flow but no sticky bolt) The bullet would not stay seated with this much powder but 84 grains is the highest max I found for a 200 grain bullet. So that is why I tried 80.


IMR 4350 65 grains 2681 2745
66 grains 2778 2767
67 grains 2843 2829 2808

The highest max I found for IMR 4350 is 69 grains for a 200 grain bullet so I will go up a couple more grains because I am not getting any pressure signs and there is just enough room.

the 200 gr TSX is a real nice load. My load was similar to yours. I was shooting one of Duane Wiebe's .300 with a Lilja 24" barrel. Shot a couple of hippos and shot through a leopard length-wise. Very accurate, feeds beautifully, and has a real punch. Here are loads I like:
200gr TSX, 73.5gs I-7828,3.380 aol, av. vel.-2880.
180gr TTSX, 71.0gs I-4831, 3.340 aol, av. vel. 3000
180gr Nos. Accu., 69.0gs I-4350,3.340 aol, av.vel. 2975

I like 200 gr. bullets in the 30-06 and the 300 magnums (take your pick).. I have been using the 200 gr Nosler Accubond on elk for the last number of years and its a great bullet with expansion and excellent penetration..I also like the 180 gr in the TSX and 130 TTSX on deer in my 30-06.
