338 Lapua and OBP-716 powder

[cega]

Anyone know anything about this powder?

http://www.gunbroker.com/Auction/ViewItem.aspx?Item=229807152

Been trying to dig around to see what I can find and other than an unverified load on Reloaders Nest here:

http://www.reloadersnest.com/unverified_detail.asp?CaliberID=140&ID=6926

and what looks like a promo blurb from GD about it there isn't much that I've been able to find.

Any info much appreciated, thanks!

Carl

I would contact General Dynamics directly and see what info they have on this powder http://www.gd-ots.com/

Thanks C.K. for the idea. I tried to send him a PM but he's maxed out so I shot an email out instead.

Still trying to chase down load data on this powder as well as another one from General Dynamics, who haven't been all too helpful so far.

OBP-715 and OBP-716 are the two I'm still trying to sort out in case anyone has any info on these at all, thanks.

Hi, I just built a .338 Norma rifle. And I'm wondering if anyone has used this powder.

Re: 338 Lapua and OBP-716 powder

Based on Mr. Johnson's post outlining how these propellants are made to the customer's specs based on components etc. plus what I am seeing of the contract it looks like the stuff I got may have been formulated for 25mm M793 Cartridges and LW30mm M788 Cartridges. So far other than the seller's listing and some non-specific GD presentations I am not seeing anything that makes me confidant that this is good to go in my 338LM.

Guess I just may have some very expensive fertilizer for the yard.

Animal -

Did you get any contract info from the guy in TN? Have you tried to look it up if you did?

Re: 338 Lapua and OBP-716 powder

I agree and waiting for some definitive answer is best. Interesting looking powder, when the light hits it just right this stuff sparkles silver, blue etc.

Re: 338 Lapua and OBP-716 powder

I've tossed what I got in the garden if that says anything.

Re: 338 Lapua and OBP-716 powder

So, I've worked up to 94.5 gr. of OPB-715 behind a 300 gr. .338" Sierra Match King with a Remington large rifle magnum primer (#9 1/2 M) in my .338 Norma Mag. The other day I was doing some accuracy testing at 300 yards. I did 3 groups 4 round groups, one was 1.8", one was 2.6" and the last one was 1.8" again. I wasn't using a bench or bags either, just a bipod laying prone, for what it's worth. I hope this stuff becomes commercially available.
