7mm RM w/ Hammer Hunter

[Sockeye66]

Looking for advice on reloading for a 7mm Remington Magnum with Hammer Hunters. Rifle will be used for a combo deer/elk gun. Powders on hand are RL23, Magpro, Ramshot Hunter, H4350 (RL26, I'll share only because it's for a close friend). His rifle is a 1-9.5 twist Weatherby Vanguard, any help would be greatly appreciated.

Just worked one up today for a friend. It's a weatherby vanguard 7mm mag. 155 hammer hunter. We tried Magpro 1st. We could not get the velocity we were looking for so we tried Superformance. Started at 70.0gr. in 1/2 gr Increments. Started to pressure out at 73 gr.with slightly tight bolt. There was a noticeable node between 71.5 and 72 gr. We settled at 71.7 gr.getting us right at 3300 fps. Verified 3/4 moa at 450 yds.
Also note that hammer bullets need more neck tension than standard bullets, and/or crimp into the center of the parabolic bands

Go to the Hammer Hunter Load Data thread. Tons of load data there. You might not have enough twist for most Absolute Hammers. Check their products page for recommended twists.

131 grain Heavy Hunter with RL 23 produced clover leaf. Can give more specifics when get home if wanted.

I shoot the 143 with rl23 going almost 3300fps -- verified .33 to .39 moa out to 700 yards

131gr and RL23 works well in my buddies Christianson. You are going to be limited mostly by twist but don't be afraid of a lighter bullet going fast..

Hammer Hunter Load Data, (See page 1, Post 8)

OK, folks. Steve at Hammer Bullets has been getting requests for load data on Hammer Hunter bullets. There is an extensive spreadsheet for Absolute Hammer Load Data developed and shared by members on this Forum. Data for Hammer Hunters is on the Hammertime Forum, but it has not been placed...
