I recently purchased a Remington Sendero in 7mm Rem mag. I shot three five shot groups with 140gr Berger VLD's and various powders and the best group meaured 1.5'' @ 100 yrds. The rifle is brand new and has never been fired. I expect much better results. Could the poor initial accuracy be contributed to the rifle not being "broken in" yet? Help!!!

Hi there, try this thread http://www.longrangehunting.com/forums/f28/getting-best-precision-accuracy-berger-vld-bullets-your-rifle-40204/
I use 168 berger VLD's and H1000. I seated the projectiles just into the lands and worked up the powder to the velocity I wanted, and got a 0.6 MOA group. I stopped there.
You should be getting better groups than 1.5" at 100 yds. Try the method in the thread above.
Your rifle just might not like 140 VLD's.
Hope this helps,
Stu.

Better or worse?

Barrel break-in isn't really for accuracy, it's more for conditioning your barrel to foul less.
Another member here found a high spot in the bedding block of his Sendero and sanded it down which fixed his accuracy problems. I found some stock paint on my bedding block which I scratched off. Look for any irregulariites in your bed. Also, go through the standard checklist. Check scope mount and rings for tightness. Is the problem with your scope. Can you check it against another know good scope? Is your bed clean and dry? Are your action screws properly torqued? Is your crown damaged?
And maybe as mentioned, your rifle doesn't like that load. But I would suspect something else. Most Senderos shoot most loads well, especially good bullets. It might be the seating too.

I bought my Sendero a little over a year ago, and when I shot it for the first couple times I was ready to throw it on the road and drive over it! But after a while of getting a custom to the gun and playing around with some loads, it shoots sub moa all day long. The smallest group I have shot was .4 at 100.
So just take your time and throw rounds down the tube to get comfortable with her.

Thanks for the feedback. I'm going back to the range on Saturday to try her out again. I really didn't check the rifle over much before I fired it the first time because i have the same rifle in 22-250 and it shoots less than 1'' with every bullet I've ever tried in it. I think i was expecting a little too much out of this gun. I also have a browning eclipse in 7mm rem that shoots less than 1" @ 100 yrds. I figure out what this gun likes!

Have you have the trigger worked on yet? Check for any tight spots under the barrel.

I did adjust the x pro trigger in the gun to its lightest setting which is probably around 2-3 lbs but it feels more like 5 lbs when shooting on the bench. I plan on replacing the trigger completely in the next few weeks. I still plan on going over the rifle before i take it out for roound 2 this weekend.
all better. some a lot better

In addition to the VLD-specific accurization steps, make sure you do a ladder test. My Sendero exhibited a significant variation in accuracy depending on charge, but by doing a ladder test with BOTH bullets I typically shoot I arrived at loads that will shoot average groups well under MOA. The gun is better than me most days.

I have had the same gun for 3 years. It's never shot over .5" at a 100. This was with 180 bergers. I've shot the same hole 3 times with 5 shot groups. Mine shot better after about 50 rounds. It doesn't foul at all. I'm going to buy a 7 ultra in sendero tomorrow. I would really look at your seating depth. All my bergers are either jammed or at the lands.
