What is the Difference between a short mag., an ultra mag.short action ultra mag and a regular mag. like 4 example. a 300 winmag, a 300wsm, a 300 ultra mag, and a 300 short action ultra mag.

The "real" difference between them is, they all shoot the same weight bullet at different velocities.

The fastest one has the most power and drops the least. BUT, it also burns the most powder and has the most recoil too.

Well, one is ultra fast and the one alot short of ultra fast but pretty fast.

300RUM shoots 180gr bullet around 3200fps or faster and uses around 90-100gr of powder
300WSM shoots 180gr bullet around 3000fps or faster and uses around 65gr of powder
300RUSM shoots 180gr bullet a little less than the WSM with tad less powder
300Win mag is a long action like the RUM but shoot 180gr around 3050fps or faster. Uses around 80gr of powder.

And burns barrels faster also.

so......as you can see per Bigcountry's numbers there aint much difference, about 200 fps from the bottom to the top. BUT, alot of guys are always looking for something new or different. I shoot a 300 RUM, because I didnt want a 300 winny because all my friends had one. I like to be different, and when I heard Savage had a few of them still in inventory of Left hand I just had to have one. Honestly, I could have probably gotten close to the same results with the 300 winny, but I didnt want one. I think the 300 RUM's are kinda starting to get a "cult" following.....dont know why

Oh yea, how many you burned out?

I did burn out a barrel actually. After 1000 rounds I had heat cracks all in the throat.

I'm not going to tell you!

So how does that effect the energy?

see you go away for a few days, and still hostile........I think you need anger management......or maybe, being a smarta$$ management

Where can i find ballistics on these guns besides remingtons website???!!??
