I tried the search first but did not find exactly what I am looking for. My main question is in what order do you go about working up you loads to shoot the best in your rifle. I have done the ladder test before but that was as far as I went. I am interested in seating depth too. Do you start with bullets touching the lands and work back or the oppisite? Any links or book recomendations are appreciated. I would like to learn how to ring every ounce of accuracy from the rounds (300wm and 308). I plan on shooting mostly 600 and 1000 yards with these.
I am shooting a armalite AR30 in 300WM, it has a 1/10 barrel. From the reading I have been doing on here I am planing on using 200-210 gr bullets and R22 and H1000 powders to start with. Second question is where do you reference bullet weight in relation to twist rate? I have a couple load books and none list the twist rate with the bullet weights. I would just like to do some research on optimum rates per bullet, just for my own FYI.
The last thing I am pondering is, I have read people on here who say they have guns that did not shoot as well with the bullet touching the lands as they do with a small jump. I do not see how that would be. If the whole goal is to start the bullet straight down the rifling why/how would making it jump help accuracy? It seems to me that would hinder things. I do understand touching the lands can raise pressures in the chamber. Is this part of the reason for setting the bullet back? Also I should mention I plan on hand feeding rounds if the oal is too much for the mag. My only interest is in the accuracy of the round,not feeding from the mag. I understand that appears to be why some are jumping so much.
Anyway thanks everyone! I am just trying to learn all that I can so I can make good choices from the begining. Any books, threads, websites, ect I need to see just let me know and I will check them out. Thanks Chris.
