7 BR for high power - good or bad?

Was wondering how the 7 BR would work out for high power?
How will it perform on the rams?
Whats a good bullet choice?
Any thoughts?

If you can put 1200 ft lbs of energy on the rams it will work fine. If it is something less, hit them on the back end and it will spin them off.

Momentum is a much better measure of ram effectiveness than kinetic energy. Please read this thread a few down the list from this one for more info. The 7mm BR cartridge is discussed in it.

Guy used to shoot one at our club. He was a hot shot at his home club. Always complained about how our Rams were set. Lot left standing. Travel around you see all sorts of Ram sets, some harder to knock over than others.
Seems to me light recoil better to go 6.5 MM than small case 7mm's.

I've tried both. This sums it up quite well.
If you want to try the 7 BR, pay close attention to Dan's recommendations re throating and bullet choice.

If you already have a 7br shoot heavy bullets in it loaded to the max, if your looking for a rifle get a 6.5 or 7mm that holds about 10 grains more powder.

Better bullet selection in 6.5 for C, P, T. If you are building it would be hard to beat the 6.5x47 Lapua, .260, or the 7x47 Lapua or a 7/08. You don't need 10 more grains of powder capacity than a 7mmBR. A 6.5 TKS or 7TKS will get the job done but there is no point to doing one with the 6.5x47 Lapua case around. Could also use Lapua .22/.250 brass and do a 6.5/.22/.250 or 7/.22/.250 and pretty much duplicate the IHSMA cartridges.
Biggest issue is to spec the reamer properly not which case to use IMHO.

I was intentionally trying to be vague as not to start the repetitive debate over cartridge selection on this forum for the 9 billionth friggin time. What I wanted to say that if he wants to try the game for a minimal investment in a factory rifle a good choice would be a 260 or7-08 approx. 10 grains more than a 7br. But I knew that as soon as I said it all the rifle freaks on here would give him enough suggestions to bog him down in specialized equipment aquisition as to insure that he doesn't fire a shot at a silhouette target from his own rifle this year.
If he wants to shoot silhouette next week go to his local well stocked gun store today and buy a 700 remington in 7-08, pick up 3 boxes of ammo, order a leupold 6.5x 20 from chicken george with rings and mounts.....assemble......shoot.

There seems to be a little attitude on this forum, hope your day gets better. What about my post was so bad? I never debated anything simply answered the question and gave some options. Maybe he wants specialized equipment and is a gun freak. Pretty pompous of you to make a statement about gun freaks.

This is my first season for trying silhouette and am using a out of the box 308. I used a friends
Silhouette rifle for one match and liked his setup so I have decided to find a used rifle or build one.
I found a used remington in a7br and was not sure how it would work for the rams. So far I am having
a good time with the silhouette shoots but I am not doing as well as I would like.

That is true for every sil shooter. Hang in there and your scores will improve but you will still say that Tony.

Nausea? If thats all you had you were lucky. I almost wrecked the truck that I was driving several times, people were on the radio yelling at me to watch out, watch this, watch that. The company finally sent me to their eye doctor, he told me that I had so much smoke blown up my ass that I couldn't see straight, second worse case that he's ever seen, one guy was sitting on an exaust from an industrial furnace (for whatever reason). Told me not to read that post unless there was at least three days before I had to go back to work, so my eyes could clear up.
