7 mm 195 berger vld 1 in 9 twist

[valleysnyper]

Guys, I am kind of a Newby here, not to shooting or rifles but to more specialized equipment I am. Going on a Elk hunt year from October and looking for killer set up. The 160 AB I shot right now shoot very good, I have shot a few deer with VLDS and they pole axed the deer. I have a 28 nosler 26" barrel 1 in 9 twist. Does anyone think the 195 VLD will be stable enough in this set up ?

Berger's website says you need a 1 in 8 twist. Their stability calculator says it could be on the cusp between marginally stable and comfortably stable depending on all the factors entered.

The 180 looks good in a 9 twist

How does the altitude effect bullet stability ? I'm at only 1000' where I deer hunt and elk hunt will be around 10000'. Sorry gor all the rookie questions, not many guys shooting over even 200 yds where I am..Gary

I have a 28 nosler with a 1:9 twist shooting the 195 berger at about 3070 FPS and so far it appears that there may be a small loss of BC associated with the slower twist but not much, I am sure my elevation(4300') helps with that. I will know more once my replacement magnetospeed shows up so that I can get a true velocity and compare calculated drops vs actual. I also have a 28 with a 1:8.24 twist that I will be comparing it with as well so I should get a pretty good idea what BC the different twists generate.

Just FYI, the new 195 Elite Hunter is a Hybrid bullet, not a VLD. They have a different shaped ogive.

The altitude and temperature have more effect on the stability than MV , at 10000 feet a 1:9 is stable at even 2800 fps in even the coldest air you will hunt in. but at 1000 feet its a different story. it calls for you to push it to its limits at 32 degrees with a 8.25 twist. Iwill say that I am shooting the 195 in a 1 : 8.5 and am right below the marginal line at 3200 fps at 32* on the calculator and I haven't had any issues with stability and my bc's have looked good to 800 yards so far, but it is on the warm side lol here we will see when I shoot at freezing this winter

You can cleanly take any elk that ever lived with a 160 Accubond . If you want to try something else, 180 hybrids are a great bullet.

I use 8.5 @1000 . There is a guy using 1.9 @ 6000 but then in his comments lower elevation might not work .

I´d stay with the 180 Hybrid. I tried both 195 and 180´s out of my 28 Nosler and the BC and Weight gains don´t compensate for the loss in MV. I´m getting 2980fps with the 195´s and 3280 using the 180´s.
I can squeeze a little more MV with the 195´s but group size opens up to over 1"

Guys, thanks for the hrlp, is there any real advantage to the 180 gr bullet over say a 160 AB out to about 500 yds ?

If your not shooting over 500 I would stick with the accubond. The Berger will expand to much and shed to much weight I believe. Attached is pic from Berger 195 at 3125 fps out 7rum from two weeks ago. Weighed around 70 grains Shot was 634 yards and bullet had slowed wayyy down and still almost completely came apart on an antelope. After seeing this I will not shoot this bullet into a bull elk shoulder on purpose ever. Double Lung shot however would be devastating but those are hard to come by sometimes in the elk woods.

Rifle is a Mcmillan Yukon EOL 7rum w 27 inch barrel vais brake 1-8 twist.

Thanks for the input guys, I'm staying with the 160 accubond
