Range Report Is there a reason the 215's shoot so fast???

[Aimsmall55]

This is simply a curiosity question. I've been shooting the 225 bergers out of a 26" bbl in a .300 win mag and I've noticed with the same powder charge it shoots faster than the 208 amax and the 210 vld. With 76.4 h1000 I'm at 2930 fps give or take a few. I shot two days ago and with a 100 yard zero it only took 20.5 moa to get to 920 yards. Is it the bearing surface? I'm not bitching.... More like dancing ... But merely curious why these are do fast...

Meant 215's in opening line. Typo

You suck!!!!!! My 300 has been in the safe since January!! It only drives the 185 vld's at 3050-ish.

Is it the bearing surface?

That is what I would suspect. If you have looked at load data you will often find bullets of the same weight (or slightly less) listing a lower charge weight to make the same pressure (or nearly so) for the bullet with a longer bearing surface. It is safe to assume that less fuel and/or more friction to overcome equals a lower velocity. Bearing surface on the A-Max is about 0.555 to the Hybrid’s 0.419.

But I am not a ballistician...

Damn ... Sounds like your. Thanks

i found a velocity increase with the 200 hybrids over 208's (80-100 fps)with the same charge also.

 

[Disturbed]

How much faster is it shooting compared to 208 amax?

Any idea of the bearing surface on the 210 hunters? Thanks in advance!

Huck , Berger has the 210 hunting vld listed as .540 bearing surface. The 215 hybrid is .419 ..... No freaking wonder they are zinging....

I found this on Berger's website if anyone wants to look up bullet stats. With a bearing surface of 0.419 and BC of 0.696, that 215 hybrid is a baaad dude, when compared to the 210 vld with bearing of .540 and BC of .631. That's a considerable jump in BC with less friction.

Wish they would make a hunter version, or even the 200gn hybrid in a hunter version with 0.450 bearing and BC of 0.624 would be awesome.

A little off topic .... But I shot a hog with a 140 hybrid out of my 6.5 creedmor and the exit hole was the size of my fist. Maybe a little bigger. Needless to say it was DRT. I think the 215 will whack the hell out of a deer. Psinclair??? I think is his name .... Is whacking antelope at like 1200 yards with them.

What range was the porker?

 

[Aimsmall55]

What range was the porker?

About 100 yards. Shot it out of my truck.

What was it doing in your truck?

Lmao. That's funny! If my wife would only ride around like my rifles do..... Silence.. Peace. Most of the time put in a place where she is well protected but can't be seen or heard... JK. I love my wonderful bride ... Fixing to give me my first son. Already got a 7-08 model 7 with his name on it. I wonder if AI makes a youth chassis??

I just switched to the 168VLD hunters in my 7 mm. RM and am getting 3181 fps whereas I was getting 3147 with 150 g Nostler ballistic tips.
You guys answered the same question I had.

There are a few that have been using the 215's for hunting with great success. One guy documented 15-20 kills last year with them ranging from elk to goats at distances up to 1200 yards.
I will be trying them on deer this year

One morning, I shot an elephant in my pajamas. How he got in my pajamas, I'll never know.

Ba dum bum.

I read somewhere that heavier projectiles sometimes have higher efficiency in lager calibers. I has something to do with the initial charge building before the projectile gets moving. Makes sense in that I read where magnum primers can actually cause projectiles to unseat before the powder is in bloom.
