Thanks,

Post by: Jamieb on January 14, 2010, 07:25:50 PM: 200gr accubond and 95.5gr of retumbo.
The 208 gr A-max also shoots real well in my rifle when seated out long but thier so long and pointy that I cant run those loads through the mag. well.

Post by: high country on January 14, 2010, 07:46:31 PM: 180 tsx on 110grs 8700. this load shoots well in both of mine. one of them also likes 7828 under a scirocco

Post by: Red Dawg on January 14, 2010, 07:58:05 PM: 87.5 gr of imr 7828 works real well with a 200 gr accubond in my remmy 700. I also like imr 4350 for 180 grain accubonds. As much as I like the AB I am thinkin if going to the 210 berger. With a BC of over .6 you almost cant beat it. I am just waiting to here more good reports on the bergers performance with big game. I have found that the 300 rum is not a picky caliber I have achieved good accuracy and consistant velocity with many different loads. I just like to use imr powders with because it seems you get a better bang for buck as far as grains per foot of velocity, because as you can see a pound of powder doesn't get you very far.

Title: Re: 300 Remington Ultra Mag
Post by: MtnMuley on January 14, 2010, 08:18:13 PM: Red Dawg, I've only shot at and killed one big game animal with bergers, and at 530yds, here was the result. We just switched to the bergers this year and are very impressed with all aspects of the bullet.

Title: Re: 300 Remington Ultra Mag
Post by: high country on January 14, 2010, 08:30:04 PM: I think long range they do killer....but what if you smash into one at 32-3300 fps? I bailed on the scirocco after killing an elk at 20 paces with my ultra.
Title: Re: 300 Remington Ultra Mag
Post by: bow-n-head on January 14, 2010, 08:33:24 PM: I'm using 95gr's of reloader 25 with 190gr berger bullets. I have shot a lot of different loads through 3 different 700 rem's and they shoot most very well.
Title: Re: 300 Remington Ultra Mag
Post by: MtnMuley on January 14, 2010, 08:35:19 PM: Not quite understanding your question, high country. Previously, I shot only scirocco bonded bullets at 3380 fps. Killed several muleys at under 100 yds, with minimal meat damage and great knockdown power.
Title: Re: 300 Remington Ultra Mag
Post by: 257 Wby Mag on January 14, 2010, 10:20:46 PM: 96 grains RL 25 @ 3460 average, 180 swift sirocco=1 killin sonafabitch..
Title: Re: 300 Remington Ultra Mag
Post by: high country on January 15, 2010, 05:32:44 AM: I shredded a scirocco on the elk I killed with it, but was less then sure if its future performance based on the pieces of bullet that were scattered in my meat. I have no doubt that they are good bullets, but IME at 3400 and 20 paces it was a scatter. the berger is not as tough as the scirocco.....so I doubt it would have been better.

not saying either is a bad bullet, cause they sure aren't......but at big velocities.......chit gets violent.
Title: Re: 300 Remington Ultra Mag
Post by: MtnMuley on January 15, 2010, 10:15:51 AM: Oh, gotcha. One of my shots at 70yds on a muley went through a rib on each side and left one inch holes through both sides of the rib cage with the bonded scirocco. I was thinking the worst at first though.

Awesome accuracy. Your post is one of the first that I have read where someone realizes where the Nosler BT belongs, way the hell out there so it won't blow up and in a weight that will retain some mass. Lots of shooters wont shoot them anymore because of their violent expansion/fragmentation at hyper velocity and close range. I have gone to the accubond in some of my rifles because it's more versatile all around and you get the same accuracy that you would from the ballistic tip. thanks for the info.

Post by: haugenna on January 15, 2010, 03:36:21 PM: Gadwall,

I must point out that I use the BT's way out there for a few reasons.

1. Point of impact and BC is identical with the accubonds
2. The BT's have proven in my gun to be more accurate at the long distances.
3. I don't know how they would hold up with that kind of velocity.

Both great bullets when used properly.
