long distance 7mm 0r 30cal

Hello folks I been off a while due to a lot of overtime but as you know the economy goes down so does the OT. This has given me some time to ponder my next project and sense Russo is working on my stock I am not super busy.

I was looking at a 7mm such as a STW or RUM, 280 AI or what ever and also the 30's Wby RUM,etc Which has the bet potential for accuracy? What are the pros and cons of each? Cover all your favorites or your hated what ever you want to bring to the table. I am pretty much open for opinions and I know you guys have them.

Thanks, in advance

RH

Re: long distance 7mm 0r 30cal

Whats it for?

I allways go with a 30 cal I dont know just love them. I know the 7mm has a much higher BC wich translates to less drop, but a big 30 like the RUM or 30-378 will have more down range energy.

Just my thoughts

Depends on how fast you can push said .30. A 168 Berger pushed out of a 7STW at 3200 will have more downrange energy than a .300 RUM pushes a 185 Berger at 3200 and the Big 7's will do it with less recoil.

I believe that the 300rum will run the 180 to 190 class bullets about 3400fps. No point in debating the potential velocity though.

If some one is going to run the big 30cal, then the potential comes in with larger bullets, like 210g to 240g. Along with more high bc offerings that appear to be on the horizon.

Energy is an arbitrary number that has nothing to do with terminal ballistics. Bullet choice has everything to do with terminal ballistics. Use a hunting bullet inside ranges where it has enough velocity to perform. Using energy as the deciding factor is like shooting dull broadheads on an arrow traveling very fast.

Re: long distance 7mm 0r 30cal

I think it all boils down to recoil. I can get 3100-3200 fps from various bullets from my plain 7mmRM. Some of those bullets don't have the greatest BC but the AB and Bergers do. Recoil is very managable without a break.

I like the 30 cal but don't own one and have only shot a 30-06 so I can't speak much to them. Like I said I think recoil one of the main factors to consider. Also you might want to read the article "What's wrong with the 30" here on the web site.

Some people love one or the other. Craig Boddington (the writer) is a big big fan of 30 cal and thinks the 7mm is a bit overhyped. I don't know him but this is an inference from his book Hunting Rifles of NOrth America.
