Home Forums Hunting & Shooting Hunting Rifles 308 win with Berger 215 VLDs

Went to the range today and fired a few rounds to see if my Tikka could stabilize the bullets at a 1-11" twist and velocity around 2400 FPS.

In conversations with MontanaMarine, decided to work up from 45.0 grains of RL-17, CCI200, Lapua once-fired brass, COAL 2.95-ish.

I forgot how poorly RL-17 meters out of a Dillon, so there is probably some of that at play, as well.

Jam into the lands is 3.070, and if I were smarter I would have just used a 30-06 magazine to get that OAL. As it was, I was shooting from a CTR mag, and even then had to single feed.

None of the bullets tumbled that I can tell.

Anyway,

Group 1 (center of target) 45.0, average velocity 2338 FPS, ES 25.3, SD 8.7, group size 2.5"
Group 2 (upper left) 45.5, average velocity 2386 FPS, ES 50.3, SD 18.1, group ~ 1.25"
Group 3 (upper right) 46.0, average velocity 2405 FPS, ES 46.4, SD 18.6, group >2"
Group 4 (lower left) 46.5, average velocity 2445 FPS, ES 59.8, SD 22.1, group ~ 1-3/4'

Going to do the long mag thing, and change powders, but wanted to get this out there just to see who else if flinging heavies and get thoughts on different powders.

The 215 on the Berger website is a hybrid target version for which Berger suggests 1:10" or tighter.

Understood.

I had some, so decided to just run the experiment.

Never know unless you try.

The way components are these days I've gotten away from this mode of thought.

Depending on elevation, etc you may be OK stability wise. Check out the Berger Stability calculator and let us know what number it gives.

For powder, I only know one guy shooting the 215 Hybrids and he uses N150 in his .308 with great results (FTR National Champion).

What twist is he using?

Hmmmm, well it seems I don't have a single photo of a test target with the 215gr Berger in my 1/12 twist 308s (Rem 700 Varmint). It's been a few years since I was testing them. My load data was:

215gr Berger VLD, moly tumbled
49.0gr RL-17
Win brass
CCI 200 primer
3.10" OAL

Velocity 2600 fps (22" barrel)

One thing I've noticed with RL-17, it seems to perform best at good pressure (QL calc'd at around 60-62K psi)

Here's a pic with some of the loaded rounds, and range data.





This is a target pic I do have with the 208 AMax over 49.0gr RL17. The 215 Berger was shooting about the same. 10-shot group at 100 yards, .65",




Rifle,

I'll ask him Saturday if I remember.

I've shot some excellent groups at 1000 yards with 155 hybrids in a 1 in 13" twist barrel and the box says 1 in 12" recommended. The stability number for that combination was about 1.4 IIRC which the Berger calculator lists as marginally stable with 1.5 or greater preferred.

Here's one of the 1000 yards with sling and irons groups that did not believe the writing on the box. Sighters on the right.

You guys are gonna talk me into a 264 Kreedmire yet,with these 215gr Booger Highbird 308 and '06 loads,that can't keep pace with the .697 BC 147 at 2700fps+. Hint.(grin)....................

It seems I'm going backwards.

My latest rifle, it makes the 308 look like a laser.....(grin)

I feel your pain,as I caught myself throwing a 264 Win barrel,aboard what was formerly a 338 Win this morning and my Kreed's are gigglin' at the 9" RPM Notion. Hint.(grin)





Don't tell anyone. Hint. LAUGHING!.................

Looks like what might potentially be a surprisingly nice rifle. LOP on that stock looks a little short though. Too bad Winchester didn't make them an 8 twist. GD

DumbDog,

Your Incredible Dumbfhuqktitude NEVER disappoints,when you are doing your BEST,you Magnificently STUPID Fhuqk. Hint.

I bought the stock here(Classifieds),sight unseen,as the lines look Skookum from afar. They only improved,in the flesh. LOP is 13.75" and your "keen" crossed eyes are always good for a fhuqking laugh. Hint.

8" RPM pushes things out of Winny's HILARIOUS version,of COAL mag "latitude". You are doing "GREAT!". Hint.

Fhuqking LAUGHING!..............

Must be the angle. Looked short. Of course, 13 3/4 ain't long. The whole 264 thing was a mess. Short throat, short mag, short neck. I reckon you'll paint this one up and throw it in the crick? GD

Will inlet and coax ergos,FL bed to fight living wood,shoot the outside hard for like reason and Devcon “stippling” for traction. Hint.

Old Worlds meets New. Hint.

Once the brush is wet,nothing matters and submersion is likely less offending. My trouble is,actually shoot. Hint.

Just sayin’…………..

go back to licking windows twiggy you don't no nothing else

Nothing is as fhuqking soothing as the Whine of Brokedick Professional Victim,extolling her Hurt
Feeler Reports,while rattling pon-pom’s from the sidelines of “life”. Hint.

Fhuqking LAUGHING!……………

The 215 hybrid kills extremely well. I've put down 2 different bull elk, 3 or so mule deer bucks, and an antelope buck with 1 shot each. The antelope was at 550 yards with a mv of 2800 and it left a large exit and put it instantly down so I'm sure it still expanded at modest speed. My 300 wsm likes it so well I'm thinking about running it in my 30-06s and 308s.

Although I bought a few thousand 225g eldms I need to give a try. I'm sure they'll work too. Although I shot a large mule deer buck behind the shoulder with a 208 amax once and it didn't touch the offside ribs. I got a new bergara fsp 300 win with a 22" fluted barrel that I'm going to try the 225s in and if it doesn't like them I'll go straight for the 215 hybrid.
