[QUOTE="Jimbeaux82, post: 1149791, member: 93815"] I have had this exact rifle for over 20 years now and have handloaded extensively for it. I have several loads which I have easily gotten MOA or a bit less with. My best bullets have been 150 gr Nosler Ballistic Tip, 162 gr Hornady SST, 160 gr Nosler Accubond. Best powders have been IMR 4350, RL 22, and VV N-160. After about 1000 rounds I noticed my groups had opened up and I could no longer get MOA, so I sent the barreled action back to Weatherby last year and had them retro fit it as an Accumark. My current handloads in this rifle are about 3/4" for 3 shots. Here is the data from my earlier MK V Deluxe, 24" barrel 150 gr Nosler BT , 68.0 grs IMR 4350, 3.340" oal, Rem 9 1/2M, 3100 fps 162 gr Hor SST, 72.0 gr RL-22, 3.400" OAL, Rem 9 1/2M, 3026 fps Current data for Accumark, 26" barrel 160 gr Nosler AB, 71.0 GR RL-22, 3.335" OAL, Rem 9 1/2M, 3100 fps 160 gr Nosler AB, 67.0 gr VV N 160, 3.335" OAL, Rem 9 1/2M, 3100 fps Please note these loads are maximum loads and should be worked up to with caution. Also, do you have a chrono? If not, I highly suggest that you get one and use it religiously when working up loads. Good shootin Jimbeaux [/QUOTE]
