At 94grs 150 miles from the gulf with the 160AB.....but what a great combo for the 7RUM.

I have shot both an Elk and deer with it.

It is a very effective combination.

180 bergers are the only way to fly. .684 b.c. and bang flop terminal performance. I get 1/4 m.o.a. with them. For powders in a 7 retumbo is the best choice imo.

Smokepole,

Linksmechanic gave good info on the Berger.

I don't shoot a 7 but have used a pecker wood 270 Win for years with 130 Sierra Boat Tails. If the deer was closer than 200 yards meat damage was always successive especially if the shoulder was hit, not bone just meat and ribs). Whole front half was pretty much wasted.

However it was bang flop pretty much each time.

I have since switched to Nosler ballistic tips to keep from blunting the lead points on cartridges in the magazine. I've shoot deer quartering away, hitting just ahead of the ham and exiting the off side front shoulder. Great penetration, great performance and bang flop and minimal meat damage.

Another question I had for some of you 7mm RUM reloaders.I tried to find the lans in mine but with the bullet just barely seated it still didnt touch the lans.One of my friends at amother site said that the ultra mag might be like the weatherby magnums and not made to seat to the lans.On the other hand I read were it said for you to reload the berger 180 gr bullets touchin the lans?That must be for the 7mm cartride and other smaller 7mm than the RUM.

Peters,
Thanks!That is what I had read for the maximum col. 3.600".
I guess that is what I should keep all the col.s at for the RUM with all bullets,dont want to build up to much pressure!LOL

I second use of the Bergers. Depending on what distance you are shooting, the 168 or 180 grains might do well. And accuracy is usually better with these bullets, being made to very good standards. With the Berger bullets, you should be able to find the lands, as they are loooong bullets. If you really want to shoot 140 grainers, Berger told me they are coming out with a 7mm 140 grain bullet later this year. And as a plus, Bergers like being shot in the lands, or very close. As an alternative to Bergers, Amaxes have done very well for me.
