7mm wbymag

[fast123adam]

what can i find out about? well here is what i know,same to slighty better as 7mm rem mag,maybe what some call a over bore? double r 90 shoulder weatherby trade mark, i am new to loading this shell(no at all new to the reloading game). I plan on loading min of 160 grs and up to 180grs. the gun i am loading for is a custom form RMR with a 26 in pipe with a 1 in 9 twist, custom model 700 action with all the goods, now can anyone help me with a load that they found to be very good at that range over 500 and beyond?

thanx for any help

Haven't shot to 500 yet.only 200. The rifles favorite load is 70.5 gr. of H4831 SC with Norma brass. Win LR Magnum primers and 168 gr. Bergers.

With your 1 in 9" twist you can go ahead with the loooong 180 gr. bullets.

I would try H1000 or RL25 with a 160 gr Accubond or 160 gr TSX

Weatherby's usualy have lot's of freebore so you may want to be cautious about starting very hot .
