If you plan on using the AB….
Sorry man IIRC means ( if I remember correctly) .086 is 86 thousands of an inch from the rifling meaning where the bullets taper from the nose back increases to full caliber .308 inches. So that means the bullet after it is fired travels 86 thousands of one inch before it comes in full contact with the barrel rifling. AB means Nosler Accubond. OAL is overall length which is the total length of the cartridge from the base of the case to the tip of the bullet.
The best info I can offer you if you are just getting into reloading is to buy reloading manuals and read them from the start up to the loading information. In this respect they are all pretty much the same with the information and cautions of reloading your own ammo just worded a bit differently from each company to the next. Get a note book and write your own notes on how your loads perform in different conditions with all the information on powder type, powder weight, brass type, trimmed length of brass, primer mfg and so on. As you gain experience it will become easier to load the ammo you want with less head scratching and fuss.
This site is also in my opinion the best one on the net for learning how to load ammo, build a rifle or get the rifle you have shooting the way you want it to. There are many members here that have so much experience in so many areas of shooting it just boggles my mind. In the seven years I have been here I have learned a lot and I load better ammo and continue to improve my shooting skills and make longer range kills each and every year.
Stick with it and you will have smooth sailing ahead.
