Can't hardly wait to get behind this thing. It's been floating around in my head for about 3 years now and finally about to happen. I'll be sure to keep everyone posted, whether you like it or not.

Sounds awesome, when do you pick it up? Who did the work?

 

[LRPV]

Tomorrow. Chris Matthews (Longshot Rifles) He has been very helpful so far.

Pics!

 

[LRPV]

Here are a couple of pics. It weighs 13.8# with the scope. Haven't shot it yet, so more to come.

 

[LRPV]

Shot a few to get started and on paper. Started with 54grs Retumbo and Berger 105vld hunting CCI br2 With a 2.293 OAL. Seems to leave a lot of carbon. Started on a 300 yard ladder over the chrono in .5 increments. 54grs got 3133fps and went up to 57.5gr which got 3267fps. So far no sign of pressure but I have to think I'm getting close. Might have to try H-1000. Nodes at 54-55 and 56.5-57. I'm going to see if there is another one coming up but the case is getting pretty full.

Looks great- how was accuracy?

 

[jonbearman]

You gotta try 4831 as well. It lists this cartridge in P.O. Ackleys book and one of the only remaining powders available is either h4831 or IMR. When I get my books next week,I will let you know as I loaded my friends 6-284 with it and shot the tightest group with a custom sporter I have ever shot. Maybe bozo(aka wayne) will chime in as he shoots this caliber. By the way,sweeet build.Its gorgeous.

Jason,
As Jon said Sweet build i have used 105 vld's 105 Lapua Scenars with good luck but settled on 107 SMK's.
I have used Retumbo, RL-22, H-4831, H-1000, VV-165, all with good luck but settled on H-4350 48.5 grains and get the lowest SD/ES with federal 215M primers in Lapua brass, single digit ES/SD. It has the capability of shooting under 5" at 1000 yards but I don't read the wind good enough to shoot better than 7" 10 shot groups yet but I am working on that As always with internet loads start low and work up. H-4831 gave the best groups, but I couldn't get the speed I needed, if I remember correctly 3030fps, I am getting just under 3300 with the H-4350. I hope this helps some,best of luck to you.
Wayne.

Thanks for the compliments. It's really not very pretty, but it's more of a function thing that I find beautiful. I have some H1000, H4831sc, 5# of RL22 that I'll probably never use, and H4350 sitting here that I can try too but I wanted to give the Retumbo a try. I never would have guessed that H4350 would be that good in the 6-284, figured it might be too fast. I use it in other stuff and really like it. ALF said to go with IMR 7828ssc but I've always found IMR to be too temp sensitive for the way I do things and found the same with the Alliant powders. I haven't tried for any groups yet but I like it'll do just fine, I hope. It's raining here right now, and we are trying to get things loaded up for Prairie doggin' 2011 so it'll probably be a day or two before I get to shoot it again.

I've been shooting a 6x284 for years. I also thought the slow burners were the key powders,. Not true (At least in my rifle) H4350( Re#19 was interesting and H4831 was also) was awesome until Re#17 showed up. I suggest you start at 46grs of Re#17 and work your way up.

How long is the bbl ? Why Med/heavy Palma ?

 

[LRPV]

28" and the taper was just what I found. Robert Whitley had the barrel in stock and for sale and I had no idea how long the wait would be to order one and other than the taper it was exactly what I wanted and the taper was close enough. How is the RL17 on temp sensitivity? I used RL22 in a 300WM for quite awhile and in 243 until I saw what happened to loads I developed in the summer and then shot in the winter (which as it turns out is a lot safer than the other way around. I don't have a lot of time to mess around with stuff in the winter, I'd rather just hunt and shoot. I decided to try the Retumbo because Hodgdon data shows it with quite a bit more velocity and less pressure than other powders. I hope H4350 is the ticket as that would simplify powder supply since I'm using it already.

Jason,
My rifle shoots many powders well, I chose H-4350 for several reasons,
#1 I have a Lot of it.
#2 The SD/ES was the lowest with this powder
#3 It grouped second best but the velocity was where I thought it should be
over 3200 fps.

I tried RL-17, the velocity was great but the groups were not very impressive and neither was the SD/ES

Remember every rifle is different, this is what worked for me in my rifle, as a matter of a fact Retumbo worked very well and had I had a lot of it I would have used it but I only had 3# of it.
I will try to post my findings with my rifle later this evening, I will go down to the reloading room and get my log book for that rifle.

Alot of the benchrest guys using 30 inch barrels are getting 3425 fps for best accuracy and they seem to be using RE22.
The nbrsa 6 target oup record held by Randy Dierks was shot using 107 Sierras and RE22.

I am shooting several 6mm-06 rifles with 30 inch barrels and 57 grains of H1000 is giving me 3433 fps and outstanding accuracy.
The node on this case is wide compared to a little 6BR so don't assume you are not already there.Your comment on the two nodes being so close together makes me think you are on the same wide node.
3200 fps on the slow node 3425 on the fast one with a 30 inch barrel.
If you call Sierra's tech line and tell them what you are doing they will give you Randy's load or atleast they used to.I believe he was shooting 54 grains of RE22.

In my rifle I believe 52.5 grains of RL-22 was a max load so at 54 I would proceed with caution.

I ran some more of the Retumbo 105vld's today. Went from 56.5 up to 58.5 which about all that will fit under the bullet. 58grs ran 3350 and 58.5 ran 3367 and were the same elevation basically same hole. This is 2 grains over Hodgdon data for a 107SMK with 56.5 at 2.8 OAL. Cases still look good and so was bolt lift, primers flattened out a bit on 58.5grs. I want to try some more around the 58gr charge and maybe move the seating depth around and try some groups. If someone with quickload would want to try to figure me a pressure number I would be much appreciative. I have looked at buying it, but it looks like it might be too much for me to figure out. 3350fps will work for me if it groups and is consistent.

[bozo699]

Jason,
You only gained 17fps with .05 grain, I would say your at the end for sure, I think I would drop back to 58.0 myself. When you were working up I would have imagined you were seeing close to 100 fps between each grain added, at some point it will flatten out, at that point it won't gain any or much velocity as you go up in powder charge, at that point I believe you have reached the peak or optimum powder charge.

I decided to switch from br2 to CCI 200 today. I have never had luck with the br2 before so I'm not really sure why I tried them to begin with. Still working with Retumbo and 105VLD-h. 56.5gr-58.5gr had a 150fps spread between them and at 250yds 7shots landed into a 1" wide 1/2" tall group with two others that were unexplained, one low and one high flyer. Nothing conclusive yet except for the primer switch, so I'm not sure what direction I'll go next. I kind of suspect my brass is not the best for accuracy (I don't have a concentricity gauge just a feeling and should be corrected after firing) but may take the blame for the fliers. The shot groups I've tried have had 2 in one hole and one over there about 2". I increased seating depth and it looks promising as it did tighten up from the previous settings. Since I'm going to use this some for hunting I try to stay away from jamming them too much but seated out to put a 1/4 of a square mark on the bullet did seem to be better but need to confirm it. Thanks to everyone for the suggestions, and don't bang your head against the wall because I haven't tried your powder yet, I'll get to it. ;D

Retumbo is to dang slow. That ES was what happened to me using IMR 7828. Try a magnum primer with that Retumbo,in order to launch those 105gr missiles
