Re: First post. 6.5x284 ladder test problem
ol Greyfox is what I consider an expert on this caliber. Follow his advice it will save you some head aches.
What is interesting is how similar some of the savage findings are. For example: at 53 gr H4831sc, I started getting pressure signs. 54 was too much. I was able to get 2900 at 53grs .015 off the lands with Berger TARGET VLDs. They had a much smaller bearing surface so pressure was lower. As soon as I switched to the VLD hunting and larger bearing surface pressure went up and speed went down.
Also, I had to pull my bullets off the lands due to a long throat, common in Savages I believe, and so far the rifle seems to like .075-.080 off the lands. This depth puts the bullet far enough in the neck to get better seating alignment and securement. It was easy to knock the bullet off center while handling.
Good luck and happy shooting/hunting. I wish I could find reloading supplies around here so I could test more and fine tune Thank god I have a good load to work with that performs well now. 2970 fps, .075 off lands, 215M, Lapau brass, neck sized, 57.5 grains retumbo. Seems to shoot consistent .35 MOA. Not too shabby, although I am hoping for .25 or less someday.

Re: First post. 6.5x284 ladder test problem
BrentM,
I have heard that about the savages aswell. Is urs a 30" tube aswell? I am using the target hybrids. Only chose them because they have the highest B.C. (0.618). Do you sort your bergers by bearing length? I have only just started on the journey of 1000 yard capable reloading so I have not done that yet. I think I am gonna have to watch for pressure signs if I touch the lands or the air temp rises. It was only about 45°f when I tested. Can't you mail order reloading components there? I am guessing ur from the USA? I am from the UK. Do u target shoot or hunt?

24" barrel.
Hunt. I am not much of a target guy.
It is hard to find components in the US right now. Freaking Obama and anti gun agenda has folks flipping out and hording supplies.

Re: First post. 6.5x284 ladder test problem
24"? You do well to get those velocities then!! I must have a slow barrel as I have 2980fps with 52.8 grains of h4832sc and its 30"!! In the UK we can just about get any components thru the post. Powder has to be sent via TNT courier ($30 a delivery) but you don't even have to prove u have a permit unless u want ballistic tip bullets. The UK government says those are more dangerous than hollow points or hornady a max's!!! So those need to be collected from a dealer and u need to show ur permit. What do you hunt? I am mainly foxes and the occasional deer.

I think your velocities are very close to what would be expected using your load of H4831sc out of a 30" barrel. A 24/26" barrel runs around 2920-2940 with H4831sc. Brent's higher velocities are being generated with a slower burning powder. I would expect your 30" barrel to run 3030-3060FPS with Brents load of 57.5 of Retumbo.IMO.

Re: First post. 6.5x284 ladder test problem
Deer, elk, bear, wolf, mountain lion, antelope, coyote, turkey. Those are the main hunting animals here. You can get a draw for mountain goat, big horn sheep, and moose if you are very lucky.
With this rifle I will hunt wolf and coyote. I primarily archery hunt deer, elk, turkey, and bear.

Re: First post. 6.5x284 ladder test problem
Grey fox,
You're correct, brentM was getting 2900 fps with 53 gr h4831sc. I was always under the impression that you got 30-50 fps more per inch of barrel tho. Now I think that's way over optimistic. 10-15 fps seems more realistic. I am happy with reaching 2980 fps. Seems a popular accuracy range for this round. On my ladder test 52.6-52.8-53.0 grains gave me the same velocity(2fps spread) and a mere half inch vertical spread on the bladder test at 500 yards. I admit this may not be particularly repeatable at this range but its a good place to experiment with seating depth.
BrenM,
Your really lucky there in USA to have such a variety to hunt. We have just deer (4 main species) and foxes plus small vermin. Bows are illegal to hunt with here. Would not want to face elk with a stick and some string tho!! Lol
