My neighbor/friend/24hcf member Broz has been shooting the 215 Berger (G1 BC .696...!) with great success in his 300 WinMag this year. He gave me a few to test in the 308, so we'll see what happens. I moly'd and loaded them up over RL17. Expecting roughly 2575/2675 fps respectively from my 20.5" and 26" 308s. I'm curious if they will stabilize in the 1/12 barrel, but the 208s and 225s have, so who knows. Only one way to find out. I'll get back with velocity/accuracy data soon, wether it be good or dismal. ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/Loading/308215Berger_zps700a8e3a.jpg)

wowza! hey, that's a bullet that might actually touch the lands in a Remmy. I assume you're just going to single-load them?

The oal to lands is 3.104 and 3.108 in the rifles. I loaded them to 3.10 and called it good for both.
This 215gr Berger is one of their hybrid designs. The ogive is tangent coming off the bearing surface, then secant out to the tip. This is supposed to make the bullet less sensitive to jump distance to the lands, and is part of the reason I loaded them both to 3.10".
Yes they will definitely be single loaded. In fact, to eject an unfired round, I have to hit the bolt release to get the bullet to clear the receiver. Needless to say, this arrangement is only for testing.
I'm heading out to shoot these today.
BTW, I did put a Wyatt's mag box in one of my 308s, it will now accomodate the 208 (or any other) loaded to 2.99" oal. That's a different story, I'll get to it in the future.

Patiently waiting for results and the story of the Wyatt's box.
What does it mean when the primers fall out of the case?

Shane--the new Hybrids like a .015" jump.
Several of the guys in my F-Class league have tried them in diff calibers, and some of the guys at the state shoot-said the same thing.
If they aren't all that great in the lands, back 'em off a bit and see what happens.
I should have just
bought a [bleep] T3...

Tag, to watch this one closer. I only got 2675 in my 26" 308 with 168's. I am interested in seeing your results.

OK, here's the results from the range. Load: Berger 215gr Hybrid, moly'd Win brass CCI 200 RL-17, 49.0gr (START LOWER FOR SAFETY) OAL 3.10" Environmentals were 30F, 25.5 Hg, wind 2-7mph from 3 o'clock, 4500' elevation. Rifles were: Rem 700 308 varmint, 20.5", HTG, MK4 3.5-10x40. ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/700s/CopyofPC210012_zps33fdd94d.jpg) Rem 700 308 varmint, 26", A5, Super Sniper 16X. ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/700s/CopyofPC210015_zpsaf14e2c7.jpg) I had 20 bullets. Ended up shooting five over the chrono, and fifteen at 100 yard target, three groups of five. Chrony F1 results at 30 feet from muzzle: 20.5" - 2508, error, 2503 26" - 2602, 2605 The error was followed by a low battery indicator (I think from the cool temp). I had to warm up the 9V battery in my pocket then reset the chrono and shoot through it quickly. Accuracy results: First group, 20.5" rig, five shots were 2" horizontal, and .5" vertical. All holes looked like good stability. The horizontal spread is probably my form being a little ganked up, bipod too low. But hey, I shot it, so I'll own it. Second group, 20.5" rig, five shots in a round pattern .84" wide by .86" tall, .96" furthest center to center. That's a solid sub-moa. I had elevated the bipod and tightened up my position. Third group, 26" rig, five shots in a fairly round group, one called flyer high. Group .30" wide by 1.1" tall. Minus the called flyer the remaining four went into .30" wide by .58" tall. That shows potential for consistent .5 moa accuracy. ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/308%20Targets/PC210002_zpsdb1d3a07.jpg) That was all twenty shots. I had hoped to take it out to 1200 yards or so with five rounds, but my first five-round group was so schitty I decided to unphuck myself and try again. Per yukonal's post, a jump of .015" would likely improve accuracy a bit. I'm still shooting the 208 AMax as my go-to bullet. But since Broz handed me 20 of these 215s to try out, I wanted to document and share my findings. For S&G, here's a traj table for the 215 out to a mile, with a MV of 2600 fps, el 4500':

Interesting that it stays super to a mile and surprised on "only" 77 MOA. Of course everyone knows you need more than a 308 to shoot to 400....  Ya need Broz to cough up a few more in the interest of science.

1800 fps at 800 yds. Hard not to like that. You could even hurt something with that load!

Yeah, 215gr/1800 fps/1550 ft-lbs, at 800 yards, is bringing it.
Drift/drop numbers are nice too.
I know, there are better choices than the 308 for 800 yards. But, if you have a 308, and optimize the load, it can deliver some respectable performance. Far more than the benchmark FGMM 168grSMK @ 2650 fps.
