Berger to introduce 7mm 195 gr EOL Hybrid Hunting Bullet

What kind of twist rate do I need for the 195 hybrid? I have a 9 twist Broughton barrel I believe? It might be 8 but I don't remember.

Sorry to be snarky but, have you read any of this thread? Have you been to the Berger website and checked their 'twist rate calculator'?

Twist Rate Stability Calculator | Berger Bullets

To answer your question though, the recommendation is 1:8.3 at a minimum. If you go 1:8 you are covered in any conditions.
 
I got 7 boxes at $62 each .....
The plan was to work up a load for moose but got them right at the start of the season and never had time to load any up for my 7mm LRH
Ended up hunting with my ole 338 Edge and shot my bull with a 300 gr Berger Hunting bullet at 60 yards for a spectacular DRT dump

I have a 7mm-300wm. It's a trued rem with an m24 contoured 1-8.5" twist benchmark finished at 27.5" with the lug bedded in an HS precision wearing PTG flush bottom metal and the 5 round 300wm magazine. It's got 26 rounds of 180's down the tube. --Ok my plan was a ladder test right of the bat at 600 with these sleek beautiful 195's...but it was too windy (gusty 20 ish) I worked up loads at 100 instead and shot them off sand bags out the window of my smiths shop. I started with H1000, virgin win brass sized with RCBS bushing die, F215m. It's 60*F at 400 ft above sea level. I started them at magazine length 3.620" which puts the bottom of the bullet below the neck/shoulder junction which I didn't think was 'ideal'. This is giving the bullet a substantial jump also (to be measured). I shot one at 69,70,71 grains into 1/2". Next 3 @71, 3@72, 3@73, 3@74. The 3 at 74 grains tightened up noticeably but also showed slightly flattened primers but bolt lifted easily and I did not see any extractor marks. I loaded up 3 at 74.5 grains and they squeezed themselves into a very nice group for me. So I hooked up the magneto which has been consistently showing 30-40 fps slower than other chronographs that have been verified at distance. I was very happy to be getting 3060 fps which means I am probably at 3100 fps!!!! With the G-7 at .387. Wow that gives me 20.4 moa drop at 1000 and 53.3 moa drop at 1 mile...still@1260fps. :D next will be verifying drops out as far as I can go. I hope these long things retain stability "out there past them treeeeees". To be continued....

does anyone have any pressure data or quickload so we can see what these loads are hitting for pressure..... I sure would like to know..... I just wonder if the extra 15 grains does not affect the velocity as much or if guys are just pushing 70-80k psi.....

I think a lot of it is the latter.... I have pressure tested data from Barnes #2 for their 195 flat base that was barely doing low to mid 2900's in their stw... we have guys doing over 3100 fps with the berger 195 in the 7stw and 28 nos... both are similar enough in case capacity that they should arrive at about the same velocity at max. pressure...

post #666 has some data from berger for the 7rum...
 
It's obvious that y'all are super dissatisfied.

I'd be glad to take them all off your hands and dispose of them properly.

Down range that is...gun)gun):D

A Barnes and a Berger are on different planets when it comes to bearing surface and bearing surface has a large effect on velocity. Most people can shoot a 215 Berger 50+fps faster than a 210 in a .30 caliber because it has a shorter bearing surface. Less drag equals higher velocity.
 
do any of you fellas have quickdesign and quickload? I was wondering if you wouldn't mind pushing some numbers for me to guestimate pressures for my wildcat....
