7mm Rem Mag Berger VLD 168 velocity problems

I'm loading the berger vld 168 gr in my 7mm rem mag 700 and I haven't seen the velocities that I've seen others report. I'm using 65.0 gr H4831SC (max load) jumping 0.010" with an avg velocity of 2830 fps.

I couldn't find any specific load data for the vld so I used the sierra book for a 168 BTHP matchking which reports a max charge of 64.7 gr 4831SC @ 3000 fps. My velocity isn't far off but I regularly see others posting velocities well over 3000 for the same setup and would like to get the most out of my rifle. That being said, my rifle has a 22" barrel and isn't very new.

I previously loaded nosler 140 gr BST's @ the same velocity with the same powder and charge weight just into the lands. I worked up a load over 3000 for it but it was all over the paper so I stuck with 65.0 gr.

My question is: since I'm at the max load already, how much farther can I go before it's unsafe and is that velocity obtainable from a 22" barrel? Also, if my barrel is worn out would it be safe to increase the max load more than 5% to get the velocity I want?

Re: 7mm Rem Mag Berger VLD 168 velocity problems

My 28" match barrel gets me about 2975fps with 70gr H1000. I don't think you could get over 3000fps out of a 22" barrel, but maybe someone else can chime in to confirm or bust this myth.

Edit. Sorry, I meant to say I have a 26" barrel. But still holds true with the barrel length issue.

I confer with you, barrel length is paramount in magnums for velocity. The bigger the
overbore the more important it becomes.

Re: 7mm Rem Mag Berger VLD 168 velocity problems

Well i dont know much about barrel lenght affecting velocity im sure it does I just dont know as much as alot of these guys.
I do know what others get from their guns probably wont be the same in yours
I am very carefull to falloew load charts and not go over the manufactures max
and alot of guys do go over.
According to berger the max load for 4831 sc is64.5 grains with a 2889 fps
Email them and they will send you a load sheet

The 22" barrel is hindering your ability to maximize velocity, H4831 may be your best bet with the short barrel. Although, a slower like H1000 may help squeeze a few more fps.

Re: 7mm Rem Mag Berger VLD 168 velocity problems

Just because the 'book' says you're at max load, doesn't necessarily mean that you are. Let your rifle tell you when it is at max. From the maximum load you have now, go up in .5grain increments (that's less than 1% increase). Watch for pressure signs...ejector mark on the case head, heavy bolt lift etc.

Ammo and bullet manufacturers have lawyers on retainer. As a result, their load data is generally rather conservative. I'm not advocating that you ignore their data, just proceed cautiously if you're going to go over their 'max'
I'm not gonna shoot here. I'm gonna shoot waaaaaaaay over there!
