Here is what I have learned so far from friends and some other forums:
H 1000 is the powder that most folks are having the most success with for accuracy and still maintaining velocity. It appears that most folks are between 92 - 100 grains - which I believe is getting to be overpressured at 100 grains.
Biggest complaint is with Remington Brass lasting as short as 3 loads and as many as 6 -7. But it seems no one is willing to pay the money for more expensive Nosler Brass, Does anyone know if Nosler Brass holds up any better? I was just about to buy brass, but Cabelas was sold out and it appears that Nosler Brass is backordered a few weeks.
I have heard a wide array of bullets, but most folks seem to come back to 165 - 180 grain bullets.
The only other feedback I was given that I thought worth sharing is that a couple of my buddies have gone to Vais Arms, Inc muzzle brakes to reduce recoil and improve accuracy. I posted this information on another thread if anyone wants to view it - Thread - "Which Brake?"
Anybody like to share on this subject? it could save me some significant time and money in getting this ironed out.
Thanks!
Neil

Remington Brass, CCI 250, 97-98gr Retumbo, 180gr Nosler Partition. I have a lot of brass with five fires, and it looks perfect with no trimming done ever. I neck size only starting with new unfired brass, and have not had to FL size yet in the custom.
One rifle is a stock 700 shooting 97gr at 3360 with a brake and holds right at .5/3 @ 100yds. The stocker shoots SAMI spec OAL, and the custom OAL is different. OAL data is in the shop but can get it if you want. Stocker only one bullet type was tried, but the custom shoot's four different 180's almost exactly the same. The custom (Lilja barrel) has no brake at 3400 into .5 also. Chronographed velocity not book.
165's in the custom go up to 3600, but groups open up to .75-1.00 depending on bullet.
As far as killing goes I have had three extremes on Elk, and deer it just slams down with one shoulder ruined. If was so worried about damage or killing power, I would go to a .243 shooting the least expanding bullet I could hunt with.
One spike shot from back to front literally into hip 2" deep, into ribs, out of ribs, across shoulder, along neck, through base of one horn. Alert and running. Looked like a grenade went off from the hair that flew off but he dropped in his tracks. Just a nasty groove the entire length of him probably fatal but only because of injury and time of year. It required a neck shot to kill him. 165 Partition at 3600fps/200yd shot. Almost no meat loss.
Another Spike at 23yds, in just beind front shoulder, and out between last rib and hind quarter on opposite hip. Dropped in his tracks. 165 Lost River at 3400fps. No meat loss.
A good long tined 5x5. In the front point of the shoulder and out the front edge of the offside back hip. Bullet recovered almost through the hide. Pretty much ruined the shoulder with about 25% edible, but minimal damage to rear ham. Dropped in his tracks. Alert and had just ran a short distance. 180 Partition at 3360/350yds.
I mentioned alert because in my experience animals that have no clue they are going to die tend to drop in their tracks faster then one spooked or ready to take off.

I was loading 96 grains of RL 25 for a pard, Rem hulls, Fed 215 Mags', 180 Swift Sciroccos', @3460 average, few ripped a hair over 3500. Rifle was a Rem Sendero. That gun would put 3 of em in a 3/8'' on a bad day...
Any pressure signs?
Might be a typo, but what is "pard"?
I have the 300 RUM Remington 700 LSS. Is that a similar action to the Sendereo?
Post by: 257 Wby Mag on December 18, 2008, 07:23:59 PM
The LSS has the same action, different snout. The Sendero has a heavy fluted snout, synthetic stock. Pard has a LSS 257 Wby Mag, its a shooter...

I've tried a bunch of powders with the 200gr. accubond in my 300 RUM. My load is 95.5 gr. Retumbo, Fed 215 primer, 200 gr accubond, PF sized RP cases, 3175fps with a very low ES.
PF= ?
ES= ?

I have a 300 rem. ultra mag I use H1000 shooting 92 grains with 200 grain accubounds and 215 primers at 3127 my hunting partner loads his with 89.5 grains his gun is 2 inches longer than mine and the 2.5 grains more that I shoot only gives me 10 more feet a second than his We both have beartraps put in our stocks instead of muzzle breaks.
your pard needs to switch to a slower burning powder. Sounds like you both are burning up all the powder. Thats a good thing.

Is it me or is that bullet buried in that case????????? Anyone else run into that?
Post by: 300UltraMagShooter on February 13, 2009, 11:10:03 PM
ok guys..... what's a beartrap in the stock? my 300 RUM Sendero weighs 10 and 1/2 lbs naked. Would that help absorb some recoil? thanks.

After going through the steps to touch the lands and then seating .015 to .03 deaper to ensure that I am not touching the lands - my COAL ends up being 3.74. I backed it off to 3.72, but this is still to long to fit in the magazine. The Magazine is actually 3.69. So I called a couple friends and they are seating at 3.63 and 3.65. I ended up putting all of mine at 3.65, as this was the longest I could be and still fit all three rounds in the magazine. I finally get to shoot this thing soon.
I loaded 165 Accubonds at 96 grains of H1000 with Fed 215 primers, I loaded 180 grain accubonds with 96 grains of powder, and 180 grain combined technology balistic silvertips with 96 grains of H1000. I will let you know in the next few weeks how it turns out.
Thanks for all the help

I was not happy with the runout (.003 to .007) of the bullets I was shooting. That might have been the problem. I changed to a RCBS Gold Medal Match Seater die. (.001 to .003) I was not happy with the seating depth either. I changed them both and got the results I was looking for. I changed it from 3.600 to 3.663.
H1000 and the 200 grain accubonds was much slower than 200 grain accubonds and retumbo. I got the 200 grainers going about 3250. Got to be too much recoil on the gun.
Retumbo and the 180 grain Ballistic Tips and Accubonds proved to be the best combination.
98 grains I had the bullet going 3350. It takes 108 grains in my Weatherby 30-378 to get the bullet goin that fast.
I ended at 100.7 and capped her out at 3487. Pretty darn fast but pretty darn hot. I backed it off a little bit to 100.2 and was moving the 180 grain BT at 3460ish, give or take. What was more impressive was the groups that it shot.
I seated the bullets as far out as I could in the magazine. COAL came to 3.663. Charge was 100.2 grains of Retumbo. Bullet was 180 gr BT and Accubonds. Primer is a Fed215M. Brass is R-P weighing 268.7 to 270.2 grains. Both had the same POI. BT were a little tighter. The picture is the BT. The gun is a Stock Remington LSS with a 26" barrel. (purchased on this site) Lightened the trigger, installed a muzzle brake, bedded the action, and replaced the spring in the bolt. ($550)
THE TARGET WAS SET AT 300YDS!!!!!! There are 6 shots here.

Nice work... I have some 180 NBTs sitting on my bench, and about 5 pounds of Retumbo... might be worth playing with.

Do you happen to know how many grains it would take to keep the speed right around 3250? And if the grouping would be at all similar?
JP,
I didn't go that low. I am going to guess around 95-96. Only one way to find out and that is to shoot it. Thats a starting point though.
I did chronograph some Federal ammo and that was right around 3268fps. The weight was 180grain, not sure the manufacturer. I think speers.
