180 VLD's in the 7mm RUM Sendero?

[su37]

Anybody have real world experience shooting 180 VLD's in the Rem 700 RUM?

Will the twist 9.5 twist handle them?

Dont mean to hijack, but if you are going to shoot 180's, why not get a .300 RUM ? I mean it can push a 180, 300+ fps faster. I understand the .284, 180gr VLD has a .659 BC, where as the 185 .30 cal has a .549. But at 1000 yards the speed is almost identicle.

Berger reccomends a 1 in 9 twist for the 180's by the way. It's all on their website Berger Hunting Bullets

Also, here is a PDF quick reference sheet for all the Bergers. Everything you need to know http://www.bergerbullets.com/Berger Quick Reference Sheets 6-17-09.pdf

My 7stw shoots them very well. It is a Sendero with a 9.5 twist. I would definitely try them.

Thanks, AND thanks Tang,

What speed are you sending them?

 

[BMcKell]

My velocity is 3050 FPS, and I seat them at 3.665 OAL so they fit in the mag. I have had better luck seating the Bergers deeper, rather than at the lands. My hunting buddy killed a whitetail this year from 1105 yards using this load. Here are some pictures of 1000 yard groups with the 180's.

Thanks,

Excellent pics,

I'm looking for a rifle that will send the 180 at about that speed.

I'm getting 3200 fps with no pressure signs. I'm gettin 3000 fps with a standard 7rm.

Ditto.
My 7mag likes both 168 and 180 at about 3000 fps.

That's very good for a 180 bullet out of the 7 RM. Back in the day when loaded for the 7 RM the best I could do was about 3000 for a 160 bullet using IMR4350 outof a 24" tube.

What length barrels and what powders are you guys using?

My 3050 FPS load is an accuracy load in my rifle and was by no means the fastest I could get. I used to shoot 140's at 3500 FPS but going to the 180's takes this rifle to a whole new class.

180

26" Shilen barrel
68g Retumbo. Max load was 69 but accuracy suffered. MV is 2950-2970.
280 feet above sealevel.

168
64 or 66g of RL22. 64 I think.

In a 27" brux I am getting 3160 fps with the 180 and Retumbo. 9 twist
