I point my bullets at targets and/or things I wanna kill. 
I didn't know there was any other way now that I think about it.

that would be it!! i had no idea that it would be that pricy, i have read good things about the process.... any one here done it?
Trimming and Pointing
The best articles I have seen on the pros and cons on trimming and pointing can be found at the following two websites:-

I know a couple guys who do it. What I gathered from them is that you don't start to see any appreciable benefit till you start getting out past 600 yards.
They made their dies by replacing the guts of Redding Competition Seater dies. The parts are incredibly simple to make and buying the Whidden's set costs a fortune. By the time you convert the price of that die to $CAN, you're more than halfway to the cost of that small lathe that Busy Bee sells (when its on sale, which is often). Personally, I'd get the lathe and make this myself. Those little lathes are really handy. If I didn't have access to a machine shop, I'd have one. There are some many gun/reloading related things you can make or modify with one.

Trimming (metplats) uniforms the OAL of your bullet.Simply,
if all the bullets have same length and weight the BC becomes more uniform and vertical dispersion is reduced.The idea is that you may reduce the overall BC by a few points but they would then all be the same eliminating the BC vertical dispertion on LR targets.
Taking it to the next step,once metplats are uniform from trimming
(let me input the Sinclair & average trimmers are too inferior to bother using and was forced to mod and rebuild a proper squared adjustable trimmer )If you want to cut a metplat square to the bullet you just can't hold them into a plastic tool and crank a handle like a pencil sharpener.
Once trimmed they can then have hollow point recut inside and allow a VERY tight metplat in repointing die.(closed) In some instances BC can be increased not just uniformed.All this MUST occur on the center axis of the bullet.
Metplats on some manufacturers bullet are very uniform (scenars) while others are all over the place (SMK's) Both these bullets shoot well the way they are but by spending some time sorting,uniforming and repointing they will overall shoot better notably at longer ranges .
Keep in mind this is not for the faint of heart and short of time.Like brass work,the objective is to produce as close to identical rounds as possible.
The result desired is to remove as much controlable variables (mechanical) as possible and have only the human element to blame when shooting .
The average shooter would benefit even if they just sorted and matched up the bullets they use before playing with modifications.
Sort by the OAL,the bearing surface,weight,etc.
A number of manufacturers use multiple bullet dies on production lines and this can be seen when sorting a lot(1000) as you end up with distinct groups.
Custom bullet makers tend to use 1 set of dies and produce a more uniform bullet.
Tedious work but results for the efforts can be shown since most matches
are won and lost by 1 or 2 points.
It does have it's place but is it worth the efforts.You have to make that call.
My only comment is beware of cheap tooling that'll cause more damage than
improvements.You do NOT want to distort or weaken bullet jackets.
Then that'll lead to the next discussion on the value's of a Juenke Machine(another story)

I bought the Sinclair meplate uniformer as looking at my 300 gr SMKs the tips were just plain ugly. After carefully trimming 50 bullets tried them in the rifle and found that they shot worse than the no uniformed SMKs. I went from 4" at 1000 yards to 5.5" at 1000 yards. The only thing that was positive about the experience is that my gongs had nicer spots on them from the uniformed bullets. I quit wasting my time after that.
Hopefully once Sierra gets all their new tooling online, the bullets won't look like the tips were cut with a chainsaw.
