[Bghunter338]

7mm REM mag 26 inch barrel, 8 twist with a long throat.
RL 23
66-3173
66.5-3208
67-3221
67.5-3259
68-3267
68.5-3275
69- 3312
69.5-3314
70-3319 ejector mark/pressure signs

Went with three rounds of 69.5 to confirm and shot a .4 moa group at 300 yards

Very nice. Going to be trying the 143's beings I have a factory barrel.

Man, that's some good shooting. What scope are you using?

 

[Zman99]

It has a SWFA 3-15 on it.

Just got back from range:
Remington 700 ADL 22" barrel 30-06 with 180HH with RL16 and W760. Both ladders ended without pressure but RL16 bulk density will lead to significant powder compression if I go further based on the COAL I have for this rifle. The RL16 ladder topped out at 2760 with no pressure but I really don't want to push this load further. However W760 topped out 2824 without pressure so I will add to ladder. So hoping it will top out closer to 2900 which is crazy with 22" barrel. Made data sheets for LRH.
Edit added:FM210 primers
Edit added: the load gaps were decision to skip that load due to low pressure and experience with Hammers. Plus save on Hammers!
The load is what I feel is safe in MY RIFLE. Use standard safe reloading practices to work up load in your rifle.

Dang forgot I shot .270 Thors Hammer!
I tried Alliant 4000MR with 156HH to see if I could get close to RL26 performance but did not run ladder deep enough but still do not think it will get close enough.

I should crack 3000 fps as I keep going on my ladder, just ran out of time today. I would be very please shooting the 260 at 3k fps even if I could push it more I have no need. On the other side, I want to drive the 213 HH like a drag racer. My goal is to hit 3300 fps with the round.

 

[GLTaylor]

VERY GOOD! ALL OF YOU! Keep me posted on your final results so I can post your good work.

Back at the range today.

213 HH & IMR4955 - No pressure found
93 gr - 3301 FPS

260 HH & RL26 - 4 shots within 3/4 MOA
89 gr - 3028 fps
90 gr - 3047 fps
91 gr - 3096 fps - barely visible ejector - no bolt
92 gr - 3113 fps - Pressure!!! Bright ejector - stiff bolt

I'll will load up a few at 90 gr and shoot. But it should be on the money.

I'm loading 33 nosler with a Redding die and 260gr. Hammer hunters, leaves just a slight witness mark on bullet, ( that's mainly because Steve gets these things so dang shiney) little steel wool and it's like it never happened

Thank You.
It was hard to find but I did locate an A Tip seating stem, order is placed guess I will find out when it gets here. I wobble tested the 2 sample packs of Hammers I have here with my current seating stem and they are pretty wobbelly
