Another thing- What is the actual OAL of your bullets? Mine measure 1.627" on average, which is shorter than advertised. That'll help with stability, as well... Using the stability calculator, it looks like you may be at an SG of around 1.53 in 40 degree weather at your altitude, assuming you have a true 9" twist, using the OAL of my bullets. If so, you'd be barely reaching the full BC of the bullet, which jives with your observations. Just don't take the rifle down to sea level in the middle of winter

Went out yesterday to verify drops as far as the scope had travel. I had verified drops to 800 during development and Ballistic AE showed velocity at 2965 fps when entering all pertinent info.
Shot a group over the chrono. Average was 2965 with an SD of 3
What a beast! Rick curious what is the velocity of that load at 1500 yards? 1600 fps with 1100 ft-lbs of energy at 1580 It may kill something

I ran the numbers as well on the Berger twist calculator. At 4000 feet the BC drops by 1% in a 9 twist.

Not Rick, but my avg hunting elevation is 10,000 feet. That bullet started at 2900 is still doing 1750 at 1500 yards. At 1000 yards it has 2100 fps and 1900 foot pounds of energy. 30338/Rick: Thanks. Seems like a lot of velocity at those distances.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

No keyholing at 4500 feet ASL, 60 deg F, using a light starting load from a 7WSM and 9.5" twist. MV is 2704fps average. First round hit on a 6x10" target at 713 meters. The bullet seems to fly just fine from the Montana 7WSM.

Got around to shooting some 195's today.wind wasnt being kind but i'm pleased so far. load on the fly Did some powder charge work at 600..Chosen load vertical at 500 seems acceptable. Shot said load at 100. the way the wind was blowing i'll take it for now.had some windage on the scope that I forgot about.. I think i'll have a keeper with some depth tweaks. This was out of my 7wby 9 twist.IMR 7977 for a 2835 average. I'm happy with that out of my 24" tube.

Hard to argue with that. With this high of BC, I can't see chasing the last few feet per second.

I went 1.5gr above the charge I settled on,going into it I figured if i could get 2800 i'd be happy. based on prior experience with Retumbo, I can no doubt get more speed burning it..I'll try some out later..Need to nail seating down and get dope so I can kill some chit on saturday . Hope to test them out on a deer..Maybe an elk

Nice results. You really should have had that range done before I left Utah...

I've got a 28" 9 twist Kreiger on my long range rifle. 7 mag. I've got about 1K rounds of Berger 180 gr hunting VLD's through it. They've been doing a fine job on Marmots out to the 1400 yard mark, but have been looking at the big .338's for higher BC bullets. With the introduction of the 195's I'm planning on just going to a bigger 7mm case instead. Still have about 600 180's left, so will be looking at another barrel after that. This gun was built specifically for long range marmots and most of my hunting is at 12000'. Will look forward to seeing everyone's results with this bullet. You guys will provide research for me. Thanks in advance.

The 195 Bergers held up really well at 3300 fps from 8 twist barrels so far but now it's time to see if they are up to the task of staying together at 3500 fps out of a 30" 7 twist barrel ..... ]photobucket[/url]

Just returned from a great deer hunt. Held out for a big buck until the last day, then shot a meat buck, a big bodied 9pt mulie with the 195 at 2970 fps out of the Mashburn. Only 200 yards. Shot behind the shoulder. Double lung He hunched, teetered for a bit, fell and tried to get up but was done. Hide showed no sign of entrance or exit and I assumed classic Berger performance. Didn't do an autopsy as I process gutless. Entrance was the size of a nickel on the left side of the rib cage and a visible hole on the exit side was the size of a quarter. My buddy held out as well. Killed a nice buck with the 168 LR Accubond out of a 7 Mag, seated on sticks at 380 yards the last hour of light. Through the shoulders and it made a bloodshot mess out of them.

Got a chance to shoot 3 195's out of my 28 going 3100fps .010 off at 300yrds. Temps were 50 degrees at sea level. 3 went into a 1 5/8" group. I will shoot a group down at 0 degrees because my fear is the 9 twist will lose stabilty. We will see. Where are you guys setting these bad boys off the lands?
