300wm rechambering to????

i am interested in having a new barrell made for my 300wm. figured i should do some thinking and research before i spend some money.

question is, should i think of rechambering to something different. first thought was 338, but from my initial research, it wont do me much good. heard 300ultra can get me some flat long range shooting! what is your thoughts?


by the way my 300wm is a savage model 110 if i remember right. has the accutrigger as well

What do you want out of the new chambering? Flat shooting? More energy? 338s are great for more energy over .30 cal, but they aren't "flat shooting". A 300RUM over a 300WM isn't a huge change in much of anything; drop, energy, extended distance while over minimal expansion velocity. IMO, you can improve those things easier with bullet choice instead of more powder. A 300RUM will be a little "flatter shooting" over your 300WM, but I'd say 95% of the critters you will use it on will not be able to tell a difference.If you go 338, chamberings will be limited to your action.

Flat shooting is my goal. The 300wm has enough energy for the biggest game in my area but I want to play at distance as well

From what I've read rechambing g to a 300rum is fairly simple and with a heavier and longer barely I can reach over 3300fps. Anything else I should consider? Cost of loads doesn't bother me to Much. Nor does recoil. Just want the most efficient rifle if I plan to start building it.

Shoot a lighter bullet for flatter trajectory and speed. I'e heard some guys run 3300fps w/ 180s. My 180gr load was a little slower. If you run 165s or 150s you'll have a flatter trajectory (at the front end anyway) and more muzzle velocity.

If you want to play at distance forget flat shooting and muzzle velocity. Look at velocity on target and energy when it gets there. I shoot a 208 and a 230 now in my 300RUM.

Only downside to going to a RUM you haven't mentioned is barrel life.

Re: 300wm rechambering to????

ok i follow you, but if i can get comparable numbers with my wm as a rum, is there any advantage to going rum?

what about other rechambering options? anything i should consider?

i don't want to get a barrell and get set up with my wm then later find out i should have gone rum, 338, etc.

I'd get either a Rem. or Win. rimless magnum case with the H&H magnum diameter head in 30 caliber. They're much easier to reload for best accuracy. Anything with a belt is a hard way to go. And the muzzle velocity spread across these standard length action cartridges is too small to fret over. Besides, any bore over 30 caliber is typically harder to shoot accurate from the shoulder; too darned much recoil disturbing where the muzzle points while the bullet's goin' down the barrel.
