[QUOTE="esshup, post: 217734, member: 11101"] 202 Sauer, .300 Win Mag, 25.75" muzzle to bolt face, .625" muzzle dia (factory barrel), Virgin Lapua Brass. I have two different bullets to try, 168gr. Berger VLD's and 180 Nosler Accubonds. I have Fed GM210M, GM215M and Federal 210 Primers I have the following powders: VV-N165 RL-25 RL-22 H-1000 H-4831SC IMR-4831 AA 3100 IMR-4350 (I have other powders, but these are the only ones that I have on hand that are recommended by Berger and Nosler for those bullet weights.) Nosler recommended RL-22, IMR-4350 and AA3100, Berger had the balance of the powders on their data sheet. I only have 100 Pcs of the Lapua Brass, (I can order more if needed). I have Federal and Remington once fired brass also, but I was only going to use the Lapua brass for this load development. To try and cut my learning curve down, what powder/primer/bullet combos should I try? How far should I try to get the ogive away from the lands for the initial testing? 100, 200 or 300 Yds? The cases were trimmed to minimum, chamfered and neck sized on a Lee Collet sizer. Right now by following the great recommendations on here, I have 50 pieces of brass with a max. runout of .0015, while 90% of the rest run a max of .002. I'll use the others to condition the bore when switching powders. I was going to shoot one type of bullet first, then switch. Temps here are in the low 80's, elevation is 735'. I can shoot out to 300 Yds here at the house currently, and I can shoot every day after work weather permitting. For a rlfle rest, I have a generic Caldwell Led Sled, and the Caldwell Rock with rear bags. With the lead sled I can durn near shoot free recoil (with very minimal touching of the gun). The scope is a Swarovski 6-24 x 50 Habicht. My normal testing "rules" will be followed, such as shoot on the least windy days as possible, and use flags, wait with the bolt open and chamber empty for "X" amount of time between shots to keep the barrel at a constant temp, etc. If heat from the barrel becomes a problem, I'll make a shield from lightweight paper and use low pressure rubberbands to keep it in place. Basically I'm looking for recommendations on combo's to ladder test (actually Dan Newberry's method). I will fine tune the most promising combos. Do I need to chrono all the loads during this prelim testing? If so, 10' from the muzzle sufficient? Thanks for any suggestions. [/QUOTE]
