Looking for some loads in 200 grain 30-378. Currently shooting a 180 grain accubond. I am happy with my accuracy, but want to try shooting a 200 grain bullet to maximize the potential of the caliber as well as higher bc's. Any suggestions would be helpful. Thanks.

What kind of velocity to you think you are getting?

I would personally look into the 208gr amax.. probably your best bet for the highest bc.

3000-3200 depending on the powder..RL22,H50bmg, Retumbo,H1000,H5010 ect.

I hope your working with a muzzle break. :)

i have been using the 30x378 for long range pa. deer huntng for about 25 years or more.
mine is a heavy bench type gun with a custom action and a 36" barrel.
ive been using 200 gr. smks exclusivly. my load is 113 gr. of h570 with a fed.215 primer.
that was a ww2 surplus powder and not any longer available.
it produces 3500 f.p.s. in the long barrel.
118 gr. of w.c.872 or discontinued h870 will produce similar velocity. h.5010 will also so im told.
ive not used the 208 hornady, or 210 berger but they shoud do very well in that cartridge.
up to 1500 yds, the 200 smk is far flatter than the 220smk, and the 240 is even further down the hill.
from that point the heavier bullets start catching up.
problem with that cartridge is that it requires a long barrel to consume the slow powder needed for max. velocity.

My best load in a 28'' barrel is 114 to 122 grains of H 50BMG behind a 200 gr partition or
a 200grain Accubond.

You have to work up to max but they exceed 3400ft/sec without being max. The 118gr load
seams to be the most accurate in my rifle.

JE Custom, what OAL have you found to be most accurate with your accubond. I have room to from the factory (3.65 or whatever it is, up to 3.815"). Also, have you had better luck with the FED 215M's or the CCI 250s?

Thanks,
Jake

With that huge case, I would look at the new 230g Berger. It will likely give you better performance (wind deflection, retained velocity, flatter trajectory) at long range than the other bullets mentioned and likely be more consistent with the right powder and if you have enough barrel.

Shooting anything less than 200g at an absolute min. is a waste in a case that huge of a case. Most lr shooters think the thing the same for a RUM case and the 30-378 is much larger than a RUM case. The 30-378 is capable of so much more than pushing a little 180 or even 200g pill.

If you're not shooting lr, then nearly any bullet will do.
