So you are "going to waste [your] time" and "breath, argu[ing.]"

Well I can see why you came back, you have acquired expert testimony!

You refer to me as, " someone who hasn't got a clue about guns or ballistics." yet you figure the effective range of a cartridge by asking "several co-workers and friends."
The funniest part is, you call me "silly."
Give me your hand, you're in need of being schooled again...
Calculating Effective Range
Open the ballistics calculator of your choice, here is web based one you can use for free.Hornady's Ballistics Calculator
Enter your pertinent information.
Press the "Calculate" button... (have your "co-workers and friends" check your work.)
Then, you need to know what targets you can be "effective" on at what "range." There are at least three schools of thought on this, some say shot placement trumps all, others say a specific energy needs to be present, while others say a specific speed hast to be present in order to facilitate the desired expansion.
Lets use the energy method, since shot placement is still a factor, and since different game dictates using different bullet types.
Since you don't know what game we are talking about, I'll go with deer.The Killing Power Of Big Game Bullets: By Chuck Hawks
It is generally recommended that a small bore (.24-.32 caliber) rifle bullet suitable for medium size (CXP2 class) game be carrying about 800 ft. lbs. of kinetic energy when it hits.
Then we need to know what bullet at what speed. Lets go with the FTX traveling at 2100fps at the muzzle.... My calculations show the 30-30 cartridge retains the desired energy for deer at about 275 yards.
Your experts are correct... unless they were talking cape buffalo.
Now lets go with the targets outlined in this post. [Yes, this is when you get frustrated and ignore what is written.]My targets are simply items I find enjoyable to shoot at. There is no specific energy I need to retain, I just need to be able to hit the target.
Believe it or not, there still is an "effective range;" and it is determined by velocity; more specifically, when the bullet's speed reduces into the transonic region.External Ballistics:The Transonic Problem
(Have the experts explain it to you.)
So using the same load above, the bullet will go transonic at about 500 yards, whereas it will suffer from, "significant accuracy decay."
Now, say we use bullets with a superior ballistic coefficient, (loaded singly,) like the SST for example.
That is 350 yards, at a target the size of a deer kill zone, with enough energy to kill deer... One shot.
It goes transonic at about 650 yards.
If you calculate the "effective[ness]" of the bullet using those numbers with Hornady's HITS calculator
, you'll find that bullet can kill "Small Game."
In other words, the "effective range" of the "30-30... round" on "small game" can be 650 yards... using the proper tools.
Next time you report what the experts tell you to regarding "effective range," you'll know to include what game is being harvested... since the experts were probably not talking about cape buffalo.
I would think a person that, "do[es] a lot of target shooting, [does] a lot of reloading and [has] hunted many times in the past, and [knows] a few things about guns and shooters" would understand this basic concept. Obviously not.
At least the other dudes knew not to embarrass themselves further by attempting debate... of course, flinging poo isn't all that uplifting, but to each their own.
