7mm Rem Mag Load data

[JK17]

Would anyone have load data for the Hammer 169gr hunter bullet. Powder would be IMR7828SSC. Shooting a 7 rem mag out. Savage 110 long ranger hunter with a 1-9.5 twist. Using SIG brass.

More than likely won’t stabilize in your 9.5 tr rifle. Hammer recommends 8.5 or faster and they are usually spot on. First I would physically measure the twist and go from there. (131 HH or 132 HHT)

won't work. You can make the 160 Sledge Hammer but would have to drop way down to 130-140 class of Hammers with that twist. You don't want to tempt fate with marginal stability. The nice thing is those little 130gr class of 7mm bullets out of 7Mag will be like laserbeams and will likely keep up with the heavy bullets out to a good distance.

Example 300WinMag 1:10 twist: the 181HH were calculated marginal for 1:10 but my Rem700 sent them sideways. The 180 which was designed to work in 1:10 puts them boringly in a nice tight group.

Get some 131 Heavy HH’s and run them +3300 fps!

The 146HH is stable in 1:10. So heaviest available stable in your twist.

I recommend the 132HHT’s at 3300+. Taking them elk hunting in AZ this year.

Second this. I have a similar 7mm Rem Mag with same slow barrel twist rate (1:9.5”) and biggest grain Hammer bullet I could find that would be stable based on Berger calculator was the HHT 132 grain bullet. Loaded it up with 62 grains H4350 powder and looks like velocity will remain above 2000fps out to 600 yards.

Just a bit nerve-racking to think of this as my primary elk round when I used to use factory 150-160 grain rounds for elk. But theoretically the copper hht will do the job. A friend showed me this: https://hammerbullets.com/hammertime/threads/vince’s-5-made-a-new-hammer-believer.1920/
