338 wim max effective range.

[Long Time Long Ranger]

The 300 ultra gives a way harder, sharper kick than the 338 win mag with same weight bullet.

Here is a recoil calculator:

Recoil Calculator

I have a 8 lb 375 taylor that shoots the 300 gr sierra with 68 gr of powder at 2500 fps. Calculator says recoil is 41.37 ft/lb

Also have a 9 3/4 lb 300 RUM shooting a 200 gr bullet with 92 gr of powder at 3225. Recoil
is 33.35.

A 250 gr 7 1/2 lb 338 win mag using 70 gr of powder, velocity of 2700 will recoil with 38.54 ft/lb.

Thank you guys so much for replying. There is som great info here. Sorry that it took me so long to reply.
What about a little heavier rifle close to ten punds. I just entered the info on the recoil calculator and with a ten pound 338 there is 31 lbs of recoil with a 250 grn bullet . Not bad at all. I know it is not ideal for packing around but to set up on a point overlooking a canyon here in idaho seems to me to be the ticket to shot those new bergers.

Just a side note I am having a real hard time chosing between my 300 wm or my 338 wm. Which would ya'll prefer. I am leaning towards the 338wm. hard choice though!
Thanks

Get the .338WM

Do ya'll know if retumbo powder will work for the 338 win. And is it a good choice?

Thanks

Retumbo is too slow. Rl 19, imr 4350, 4831 are all good powders for the 338 win.
