It would appear that using bullets that are very tolerant of jump would work in your rifle. bullets like Nosler, Sierra, and Swift would be my first choices with the 140gr BT being first.

Hi guys,
I have reloaded a fair amount, but am by no means an expert. My experience has been to stick with a recommended C.O.L., and vary loads by varying powder weight until I find the best load.
This has served me well, but I feel I am missing the boat, by not playing with seating depth. I feel I can improve the accuracy of my pet loads by doing this, and maybe make a "poorer" load "better"
For example, I made 4 loads with 120 gr speer bullet in the 6.5x55. Used 42,43,44, and 45 gr of H4350 All at a recommended C.O.L of 2.995"
The best shooting load was the 43 gr load, 1.25 inches at 100 yds from my old M96 Swedish mauser. The 45 gr load shot 1.75"
I would like to get the 45 gr load to shoot better, and have the velocity and accuracy. After all, isn't that why we reload?
So my question is; How do I BEST go about finding the best seating depth?
Is there danger or risk to going too long or short?
Thanks for your input. OAL can be determined by examining the size and shape of your groups. If the groups are large equilateral triangles, the bullet needs to be seated out further and it will close the group. I use qtr turns on the seating die to fine tune. If you get the more common 2 bullets close together and the 3rd out of the group, the bullet needs to be seated deeper. Again, I use qrt turns on the seating die to fine tune. John

Interesting, John. I'll have to try that.

I have had a lot of feedback from people who have tried it and so far, not a single person said it did not work.

Cool. I get nice groups, but often they look like the triangle. Thought it was just the jerk behind the trigger.

IME John is certainly correct about the the 2 in one hole, one flyer pattern.
I have a rifle shooing the equal lateral triangles....I'll have to try lengthening the cases out a bit.

Take all the guess work out of it and use the Hornady oal gauge and the Hornady bullet caparator. When used together its perfect! This is the only way to fly, and it'll save you tons of time and heartache.
It is irrelevant what you think. What matters is the TRUTH.

Use the "Cleaning Rod" method with rod stops. I've checked it side by side with the Stoney Point tool and it's just as good.
You will not have to buy the stupid "modified cases" for each cartridge you own. The cost is about 6$ for the rod stops from Sinclair. You already have a cleaning rod.

In a 6.5x55 shooting 120's this is likely moot but in my rifles I now start by measuring the magazine and loading just long enough to fit. More than once I found great COAL's only to have them too long for the mag when loading two or three in there.
I would guess you have all sorts of play room with your combo though. Isn't rule of thumb to load at least as deep as the bullet diameter?

btw- correct spelling 'comparator'. Just clarifying in case he looks on line.

I think the best approach is to start touching as there's only one way to go from there. Many times touching is a done deal for the seating depth routine. With an exception being monos, which seem to like a jump. I've also found that a really good tube will handle multiple seating depths equally well.
I like to use one bullet from a lot to find the lands and set up the seater. Keep that one bullet for future SD changes until you run out of that lot. You have to do it all over with a new lot.
