Comparing the Berger 210 VLD to the 215 Hybrid

Of course I discovered the same thing a year ago when I compared the 210 VLD hunting and a 230 Hybrid Target in the same manner. I measured from the base of each jacket up to the ogive in six different places. I measured twice in order to get an average on each measurement for each jacket.

210 VLD Hunting average thickness between all measurements: .0218"

215 Hybrid Target average thickness between all measurements: .024"

That leaves a difference of .0022" between the two.

I did notice that both bullets start out at the base with a .027" thickness. The 210 VLD quickly drops to .023" thick just .125" above the base. It gradually tapers off to .019" into the top part of the ogive.
The 215 also starts at .027" but gradually tapers from the base to the ogive and measures .0205" near the top of the ogive.
Not sure this is usefull to anyone else but it tells me that that jackets are so darned similar I just don't see a performance difference between the two bullets based off of jackets alone. You will notice that the lead core in the 215 does not extend far into the ogive of the bullet like the 210 does. I suppose this could create some differences in performance? Good or Bad? I guess we'll find out very soon

From top to bottom: 215 jacket, 210 jacket, 210 lead core, 215 lead core

Good job! I'm thinking the tips may have blown off without expanding, as my test pics show, because there is nothing to support them (lead). For whatever reason, they acted differently.......Rich

First let me apologize for taking so long to test these bullets. It has just been a little crazy this summer helping others with load work ups and tuning rifles. But the reports will now come in.

All I can say is Holy Crap!!! I hear all this doo doo about Bergers taking many rounds to tune.. Well.. that is only true if you consider 6 alot of rounds.

I loaded 3 rounds with H-1000 seated -.040" off the lans. I backed off 4 gr from my 210 VLD load and loaded 3 stepping up 1 gr each shot. These 3 shots, from a clean, unfired cold bore, and with 1 gr difference in charges, shot a group size of .402" c/c. I seen that the top charge was close to or maybe right at max pressure, but bolt lift was smooth, so I loaded 3 more at that charge -.040" off the lans, and made a slight zero adjustment. Shot those 3 off a harris bipod and a rear bag prone. Group size was .190" c/c ES at this time was 7.... I was done! But I wanted to correct the zero 1 click so I loaded 3 more. Huge pilot error on the first shot with a poor break of the trigger. Then shot the two left. These 3 even with the nut behind the bolt pulling one, shot a 3 shot group of .682" the two good break's went into a figure 8 hole of .216 c/c. 6 shot ES was now 9.

Now here is what excites me. Average veocity for those 6 with ES of 9 was 3035 fps across my Oehler 35.

Baro=25.64
Temp=58*
Hum=10%

Run some drift, energy and retained velocity numbers on this old 300 win with a 215 at 3035fps and a BC of G1 .696 and G7 .356. That will make some 7mm boys cry...

I will post some pics tonight. of the target.

I will take this info and get it loaded into Bryans AB program and tomorrow I will be confirming drops to 1200 yards.

Then I have some Wy. and MT. test media tags known as Pallamino Speed Goats. I plan to take some goats both near and far to see how these bullets perform on real meat and bone. If all looks good we will take a some Elk with them later.

Thanks for the update. Looking forward to results and pics from 'test media' shooting.

You got it. I try to always post terminal performance pics. They are for my records and I have no problem sharing them so you can draw your own conclusions.

I'm really looking forward to your findings too. I want to try them but only if they show promise.

Here are the pics of todays shooting and load work up. Again this is a max load, in Lapua brass, in a custom rifle with a custom chamber and throat. Work up from well below this level. Not many rifle would shoot this load safely.

Wow! That's great Jeff! I knew you would love these! I was pretty sure you would get over 3K with these also with their short bearing surface. I was able to do the same when moving from a 210 to the 215. Looking forward to hearing and seeing your on game results!
