This New "Remington Ultra Mag" (RUM) cartridge should be a hot selling item. Handloading 140 grain Nosler Partition bullet, load is 93.5 grains of RL-25 powder, Federal 215 primer, this load delivers around 3493-fps at 15-feet.  Reduce all Initial loadings by 10% but, NO More!

For deer and antelope at long range, the 150-grain Swift Scirocco bullet with 94.0-grains of H-1000 powder, Remington 9 primer will deliver around 3281 fps at 15 feet.  "Reduce" all Initial loadings by 10% but, NO More! Slow burning powders can detonate instantly like dynamite when the load is reduced too much!

Swift A-Frame, 175-grain bullet, 98.0-grains H-50BMG powder, Remington 9 primer, delivers around 3014 fps at 15', great for elk, moose and bears. You might feel some recoil with this load with a heavier bullet and powder charge! Reduce all Initial loadings by 12% but, NO More than 12%! 

Nosler Partition 160-gr. bullet, Powder- Retumbo-94.0 grs., Rem. 9 pri., 3212-fps @15-ft.

Barnes XLC 160 grain bullet, RL-25 | 91.5 grs. powder, Fed 215-pri., 3233-fps. All @15 ft.

Hornady spire-point 175 grain bullet, IMR-7828  powder, 80.5-grs., Fed 215 pri., 2950-fps.

Nosler (BT) Ballistic Tip 150 gr. bullet, 89.2 grains Magpro powder, Rem. 9 pri., 3324-fps.
Good bullet and load for mid-range on deer & elk. You could sight your rifle in with the long range 150-gr. BT loads and find another load with a close enough impact point at closer ranges for those shots.

The Heavier Premium high terminal performance bullets are a better choice over the 140 grain bullets for larger animals in this ultra high velocity cartridge. Also, the Ultra large case volume to bore diameters' normally perform better with heavier weight bullets.

I've probably made a lot of enemies posting the reality concerning leading running game, as I have heard every imaginable story of how "the critter was running at top speed 300 yards away broadside and I held on his nose and blew his brains out." "Oh yes, this ultra mag bullet gets there at the speed of light." Well, if you  were shooting the above 7mm Ultra Mag with a 140 grain Nosler Partition bullet @ 3425-MV and the deer was running broadside at 30mph/44fps at 300-yards (no cross winds) bullet flight time is .296-sec X's 44-fps, you would have to lead his brain by 13' feet! That's pure unchangeable ballistics math that can't be modified much by a mere miscalculation of reality.  At any rate what I put on the chart is very close to the required lead, barring a lot of other factors I won't list here; you can probably think of a number of them.

If you wound an animal it can be very important to make a vital hit on a moving target.

Shooting at running game is a lot more dangerous, exercise extreme caution!

The 7mm-RUM (Rem Ultra Mag) is the ultimate performer in the 7mm caliber arena. Even I have a deep interest in it, but I realize that I have some problems that tend to limit me to the recoil of the 6mm caliber's, therefore I can shoot better with my 243-06 Wildcat.

Hunters are already shooting moose with the new 7mm Rem Ultra Mag with excellent results. I like the fact that it is a beltless cartridge case. 

I know a guy by the name of Ray K. -- in Prairie du Chien, WI that can come close to cutting 3 shot jagged holes with his hand loads in his 7mm Weatherby Mag at 100 yards at the PDC outdoor bench-rest range. Ray K., also has a 7mm Rem Mag that is extremely accurate.

I just read an article in the advanced June issue of "HUNTING" magazine by Grits Gresham, where he says Whiskey Chamberlain of Idaho told him that he hunts elk with a 243 Winchester. Whiskey Chamberlain said he had killed 15 consecutive big bulls each with one shot, and hadn't lost any using a regular .243 Winchester.

They list the .243 Win. with 100 grain bullet as getting 2960 fps MV.  My 243-06 Wildcat should deliver over 3400 fps MV with a 100 grain bullet. With well placed and properly distanced shots the New 100 grain .243 Premium Bonded bullets should do the job on elk.

Rick Jamison writer for Petersen's Hunting Magazine, July 2002, p- 20, Guns & Loads Article Long Rangers, - http://www.huntingmag.com  says in essence that for deer sized game you need a minimum of 1000 ft/lbs of energy and 2000 ft/sec velocity at the impact range for adequate bullet expansion. The bullet needs a sectional density between .215 to .265 and a high ballistic coefficient for long range shots. This is a great Hunting Magazine, I subscribe through the local school magazine drives.

You can look at the various ballistic tables I have on the Net and determine the approximate outer range limit your cartridge and selected bullet will be capable of killing a deer with a well placed shot. If you can't put the bullet in the vital kill zone don't take the shot no matter how capable the cartridge you're using is at that range.
