The 7mm RUM and 300 RUMdoes it hands down as for energy at long ranges.

For extreme long range deer hunting, the 7 STW is hard to beat.

RE: .270 max. range
I don't know how we got to the 7MM STW when we started with the 270. Going by Roskoes 2000 fps, the 130 grain 270 with most loads retains 2000 fps out to 600 Plus yards with 1000-1300 LBS ME depending on the bullet. Why anyone would need or want to shoot at deer past 500 yards is beyond me.
As someone else said, the Max range depends on the shooter but thats what the rifle is capable of without the Rambo factor figured in. We used to have a free day at the steel silhouette range now and then. It was down right comical to see where most hunters were hitting with their rifles shooting at the 500 Mater Ram. Most were hitting the ground at least a 100 yards short of the target.

RE: .270 max. range
Just making a comment about that round. . I can honestly tell you most hunters who call 400 yard shot off walk up to my range and think that the 400 yard target is mile away. I am very sceptical of some of the ranges most hunters quote. And no I dont want to argue over it ,I have just seen alot of mistakes in yardage judgements. I do think that the .270 win will take deer at most hunting ranges as well as ant thing. It requires a good scope ,with target cross hairs to do it. At or around 300 yards most cross hairs on hunting scopes cover up the animal.

If this was the case, The 30-30 wouldn't be any good at 100yrds.Along with 50 cal muzzle loaders. The bullet (energy) has more to do with effective kills rather than the speed velocity. Look at a 44. 1300 FPS. Many kill deer at a 100yrds easly with it. Then again, I am just starting to understand ballistics. Heres a chart from remington that's easy to read and compare ballistics.

Look at the ballistics charts. The point at which the bullet falls to the 2,000 fps impact velocity is effectively the maximum range.

Your missing the point. A bullet designed for big game in the .270 requires a certian speed to open up. This will be faster than other calibers. A 30 30 is a slower moving round from the start and as such is designed to open up at slower speeds. Same applies to the 44 mag. If the .270 bullet was designed to open up at 1300 fps it would blow up on the ribs on a 50 yard shot before it could cause a decent wound channel. The speed a big game bullet will expand at is dependant on the weight of the bullet, its construction and the speed it will be traveling. If too strongly constucted it will not open up causing a small wound channel. Too weakly constructed and it blows up on the surface.
Any good big game cartridge will have a bullet designed to work within its expected velocity range.

RE: .270 max. range
I know what you mean about range. Most guys who came out the the range would not believe how far 500 Meters is. The ram is about the size of a deer but it looks about like a rabbit at 500 Meters. For most of them, I had to stand a 4x8 sheet of plywood behind the ram to even get them in the area. It was funny at the range but its not funny inthe field as they MIGHT get close enough or unlucky enough to hit and wound one.

RE: .270 max. range
Although not quite on subject, I thought I'd add that the single farthest shot I've ever seen on an elk was 435 yards (per Leica rangefinder). The 5pt bull dropped in his tracks.
Upon examination, the bullet entered just in front of the near shoulder (slight raking angle from the front) and left a massive exit wound after breaking the off shoulder. It was a 140gr Nosler Partition fired from a 6.5x.284, a cartridge that has very similar ballistics to the .270 Win.

RE: .270 max. range
The 140 and 150 both retain 2000 fps at 500 yards. 2100 for the 140 and 2009 for the 150. These ballistics are from Barnes but are doable over my chronograph. There is an amazing lack of difference in performance of the 270 with any of these three bullet weights. Very little actual differnce in POI either.
Canwoodsman. Thus the 130 grain Nosler Partition. It was designed to do exactly what you describe. Its been doing it very well for a long time now. The Nosler Ballistic tip does fine at the longer ranges but does not hold up as well as the Partition if close shots are encountered. I have found though , no fault in the field with the BT either.
