The pic below shows my 700 classic .35 Whelen with some Nosler Ballistic Tip 225 grain ammo I loaded. Those shot well.
I now load Barnes 225 grain TSX bullets in it. I found out right away that those Barnes bullets really are tricky to load for to find the right combination...but I did find it for my rifle. I reduced the powder charge in small increments from what worked well with the Nosler bullets. I also found the Barnes recommended load range on their web site was not best for my gun.
With the Barnes 225 grain TSX in my Remington 700 Classic I use 55.0 grains of IMR4064. 3.374" OAL gives me the best groups of 3/4" - 1" at 100 yards off a bench rest of course.
I shot two whitetail deer with the handloaded Barnes bullets this year. One deer went 10-15' and the other was DRT. Bullet in and out just like I like it...blood spray out the exit of about four feet. Both were shot just behind the shoulder. Massive internal organ damage but all the meat was fine.
