Help with 143gr Hammer Hunters in 7 rem mag

[cb4128]

no I'm not

 

[GLTaylor]

That's fine. You haven't mentioned groups, es or sd. I was just curious.

 

[cb4128]

Haven't shot for groups yet but hopefully soon!

 

[Korhil78]

No one has asked this and it is important I think. How far are you planning on taking game with this combo?

 

[cb4128]

600 yards and in

 

[Korhil78]

Gotcha. At the speed you are getting with 69 Gr of RL26. You will be just fine even out to 700. I'm sure you will find an accurate load. They shoot really well.

Try more jump and slowly increase powder til you find pressure, then back off 1 grain and shoot for groups.
Don't hesitate to jump .050 or more if you have room for powder.
Also need your twist rate

As GL said try more jump, I seat all of my bullets to the last PDR groove ( Powder charge allowing) and have never had to change anything

 

[cb4128]

Oh wow ok, so seat them pretty deep then? I'll try .020 off and seating super deep and report back

 

[Korhil78]

I found my 7 mag to like .030" off but that was with 169 Gr hammers. I have never loaded hammers real deep and they shoot really well.

I've found good luck with 143's in 7 mag seated at SAAMI spec length. I use Nosler Load Data for OAL length. So they are fairly deep.

 

[cb4128]

Sounds like they're pretty insensitive to searing depth with all these different positive experiences!

That's exciting

Seat them to the last PDR groove( powder allowing )

 

[cb4128]

Do you have a pic of where you seat one of your bullets? A loaded round I guess…bottom of the last groove, top of the last groove etc
