195 berger elite hunter

just stared load work ups 7mm rem mag krieger barrel 28" 8.5 haven't broke 2800 fps yet 40-50 degrees 7828-63g 2766, 4350-59g 2766, retumbo 65g 2754, 4831-62g 2789

also have load data for sierra 183
 
I use 7828 long and short cut in two different 7mags with 150gr to 168gr bullets.

I think you might get better velocity with a slower powder for the 195s with Rl33, h1000 , even rl26. Maybe.
 
I'm at 2850 with H1000 in a 28" Hart barrel using 68.6 grains of powder--the bullets are 0.020" off the lands and are hBN coated. I've had no pressure signs in my rifle, however, one of these in a buddy's 7mmRM exhibited the flattest primer I've seen, so I'd definitely recommend working up.

What is you oal to the tip? I want to know if it will fit in my magazine?
 
67.5 grains of Retumbo at 3.53 oal is getting me 2820 fps out of a 25" rock barrel. Been effective on black bear, antelope and mule deer so far. Went all the way to 2900 fps but backed down to this speed with outstanding accuracy.

Sorry for the slow response, I was in Montana where I took my first elk! (Just a little excited about it).

The longest OAL is 3.485" for that rifle. Most of them are a little shorter--these are from the first run of EOL bullets offered for sale. The CBTO is 3.722".

I have another 7mm that I had a custom BDL-length reamer made just for these bullets and I am using a newer batch of the bullets and they are far more consistent with the length of the bullet. The OAL is the same at 3.485" but the CBTO is 3.771".

Just for comparison, I'm using H1000 in both, but the heavy rifle with the shorter CBTO has 68.6 grains of powder resulting in the 2850fps velocity in a 28" barrel. The other lightweight rifle is only using 64.8 grains and I am getting 2700 fps in a 23" barrel.

I stopped at an excellent node with the lightweight rifle that doesn't generate a lot of recoil--2700 still gives me an effective range of 750 yards on elk (based on 1500 ft-lbs) and 850 yards on deer (based on 1800 fps) so I didn't feel the need to push it.
