berger hybrid bullets ...updated 6/8/12

[BULLBLASTER]

Thinking of trying some Berger 215 grain hybrids in my 300 rum. With a BC of. 696 they should be pretty flat shooting. I ran numbers and with the same velocity as Berger 210 there is over 1 moa less drop with the 215s. Should be less finnicky on seating depth also. Anyone tried these yet?

I have been talking with rbros on here and that is the bullet he is going to be building his 300 ultra mags around.

The 215's are working well.  Seating depth works best within .015" to touching for the best accuracy.  We were all hoping they would like any "jump", but that doesn't seem to be the case.  They do shoot well, but generally make the rifle a single shot, even with a Wyatt's extended box mag.  3150ish range in 28" barrels is pretty easy to get with 1/2moa accuracy.  A 10 twist barrel is needed and doesn't seem to shoot as well in the 11 twist rifles like the 210's do.  Only have about 200 down range so far, but it looks promising for the 30 cal.  Turns the 300RUM into a new animal for sure.

Screw the Bergers! They cant do anything the 208 A-Max has done, is doing and will do.

Except shoot flatter, less wind drift, and hit a little harder.  Both will perform the same on critters for sure.  The A Max is a little softer than the Berger, but both will kill.

Based on my results on paper at 1k, the Berger does shoot flatter and less windage by:

Elevation: 9.25"
Windage: 6"

It hits harder by 200ft/lbs roughly according to the ballistic programs.  I have shot these several time on paper at 1K to see the difference in 300WM and 300 RUM and the results are pretty damn consistent.

In my research I have found the Berger's to have better specs. But wouldn't mind trying.some amax bullets. Thanks again rbros for the assistance. I will let you know when I get some loaded and shooting!

i ordered 8 lbs of retumbo and 50 of the 215 grainers to try out. got load data from berger as well. i will post after i shoot them.

finished setting up my reloading set today, and made a dummy round for length using the 215s. these would be 3.9 inches OAL to touch the lands. i will try loading at 3.69 for my first development rounds. i hope they will shoot with that jump. it shoots well with the 210 vld and .1 inch jump, the hybrid supposed to shoot well with more jump so we will see.

I think what needs to be made clear here though, is that The Hornday A-Max, is NOT designed for hunting. Not to say it can't be used.. but know that if you use it, and it does not do what you want, its because its a target round and not meant to used on Animals.

The Berger 210 VLD on the other hand IS made for hunting.. so..

Make sure at 3.69, that you can load your magazine before you build too far/much.

Have you witnessed what a 208 A-Max does to Mule deer and Elk at extended ranges with a .300 Win Mag pushing it? I have, it's a very effective bullet. I wouldn't trust it point blank, especially with a Ultra Mag case behind it. In close it acts just like a SST at higher velocities, a very effective rockchuck/varmint bullet and thats it.

yep  that is the longest that will fit and feed. same length i was loading the 210s. the 215 are .1 or so longer on the nose causing a bit more jump. may load a few tonight, then have to find time to hit the range.

I have a extra Wyatt's ultra mag extended box mag if you would like it. With a little fitting you can seat them out further. If they don't shoot for you seated deep.

Thanks Hammer!

i have wanted a wyatts but wasnt sure about installation, i dont have a mill. would most smiths be able to install it?

i loaded up some development loads starting lower and working up. maybe ill get to shoot this weekend or next.

I have the Wyatts extender in one of my custom RUMs, and it didn't gain me any OAL.
