I just like to hit an animal with as much force as possible ,,I have never been on an elk hunt but if I did I would want all the energy I could get,,

I'm with mr big on this. Get all the speed you can without sacrificing too much accuracy. A 2" group at 200 yards is great in my book. As far as seating the bullet, there are tests you can do to see if your gun likes the bullet seated on the lands all the way to having a bit of jump. Personally I want mine as close as possible without touching. Book oal means little to me.

I agree, but how much difference in energy would a grain or 1/2 make overall? Guess i could answer my own question by running it through a ballistics calculator....

Again yall, thanks for the answers. I have read my reloading manual over & over, but there is nothing like "real world" experience. I visit a lot of forums, but this thread has given me more insight than all the other reading i've done yet.

I've read on other forums and possibly in my manual that you can get to a point where a full grain of powder will only increase your fps by a 100 or less. To me that's wasted powder with no result. I wish I had a chronograph to to help compare my loads. But for now I make up loads until I have exceptable groups. I've switched powders and since I haven't had nothing exceptable. I like mr big's way of finding loads. Sounds more efficient and safer than my way of finding the right load.

if you shoot the one grain increment loads at the same target you should be able to see the sweet spot also,,when you see two or three different charges start grouping together you are on the accuracy node,,say if 64,65 and 66 grs are in a close group with the others stringing ,you will find a good shooting load around 85 grs,

I have found with shooting Barnes bullets that seating the bullets just off of the lands is not very good for accuracy. For some reason Barnes bullets are more accurate seated deeper. In my 300 WSM's, I have found that Varget gave me the best velocity and accuracy for the 165 grain TTSX seated down to the last ring showing. I tried all sorts of seating depth's and got on the various shooting forums and they pretty much all said that seating the bullets deeper gave them the best accuracy, and they were right.

Model7man. I load Barnes ttsx for a friend and with 44.6 grains of varget under that 165 grain bullet in a 308 is awesome out of his gun. And I have 2 rings showing. I guess it's all in the difference in guns.

That is true. Some rifles are throated deeper than others. What rifle are you loading for?

So much bad info above, I don't know where to begin. Big is correct and M70man is close.

Barnes data is hotter than most. Reaching "their" max with "their" bullets is almost impossible, but that is besides the point.

Start by touching the lands. Your test loads are at max pressure here.

If you can't reach the lands, load to mag length. Your test loads are still at max pressure here.

You see if you start long (OAL) and work up to pressure, you're always safe to lessen oal.

Starting .10 off lands is stupid beyond belief. Let your gun tell you where pressure is. Not a book or not a poster on tndeer.

Good luck.

FWIW, I shoot a lot of Barnes.

tsx and ttsx

When possible (mag length constraints), I load them jammed 0.100 into lands.

Most of the time, a powder charge difference puts them into tiny groups without varying oal.
