Re: H1000 in a .243 with 87gr Berger VLD's

A much as I hate to ask because its about H1000 has any one tried retumbo in the 243. I was thinking about that with mag primers with a 90 grain accubond or a 95grn bergers. Any thought on this?

Re: H1000 in a .243 with 87gr Berger VLD's

I don't use Retumbo in my .243 but I do use it in my 25-06 with great results. It is the best powder I have ever tried in my 25-06. I do not use mag primers with it though.

I don't think H1000 and Retumbo are limited to big magnums. I believe they are actually made to function well in any overbore type cartridge. The .243 and 25-06 are considered overbore. Seems heavy for caliber bullets are prefered when using them in any cartridge. For example I use 110 Accubonds in my 25-06 with Retumbo.

That's why I got interested in this thread. I may try H1000 and Retumbo sometime this winter in my .243 also. Seems like a good idea.

There are Retumbo loads for the .243 on Hodgdon website also. Just for heavier bullets though.

Re: H1000 in a .243 with 87gr Berger VLD's

I've seen those on there web site. If my wife's rifle had a tighter twist barrel then I wouldn't think twice about it and get some of the heavy 107grns bullets but I think it only has like a 1/10 twist. Along time ago I seen where I think it may have been the best of the west crew working on a kids gun that was a 700REM bull barrel 26 inch gun that had the tighter twist and they were using retumbo and some heavy bergers I think. Not 100% sure but I think it may had been John Burns. I thought they were using retumbo powder in the rifle. Reason for wanting to use retumbo is I could have all my guns shooting retumbo and just buy in bulk but I have to get through the rest of my powder first.

Re: H1000 in a .243 with 87gr Berger VLD's

Well guys, last night was interesting to say the least. The rifle range was absolutely packed. There was only one bench left open, and there were no target stands left at 100 yards. So I ran a few targets out to the 200 yard line and began to shoot my groups of 5, working up to find my max load. After I shot every bullet I never found my max load, even at 47 grs with a WLRM primer. To my surprise, this load (47 gr H1000, Winchester Brass, WLRM Primer, and 87 gr Berger VLD .0075" off the lands) shot far better than the others. Unfortunately everyone else at the range thought my targets were there for everyone to plink at. So I didn't take pictures of any of those groups while working up. They were just too hard to determine what was mine and what wasn't. I did however keep one target, and my best group, to myself (Shown below). I know it's not a great group at 200 yards, but I was not prepared like I should have been. The sand bags offered at the range were all taken and I didn't have my own with me. So this group was just off a bench with a 13.5-23" bipod (My coyote hunting bipod). Another thing that was difficult to over come, was trying to be steady while 2 guys are beside you burning through 223 rounds (AR's) like they grow on trees. Another mistake I made was not bringing my chronograph. So all in all it was not the most productive night, but at least I have a decent starting point. I'm going to load several more rounds at 47grs with different seating depths (according to bergers recomendations) to see if I can squeeze some more out of it. I will also get some velocities the next time I go out.

Re: H1000 in a .243 with 87gr Berger VLD's

47 grains of H1000 and the 87 grain Berger with CCI LR gives me a Average 5 shot group of 3196 FPS on the magnetospeed.
I'm Very happy with this it is a factory Remington 700 CDL it will produce .4s-.5s at the 100 yard line all day if I do my part. I seat to magazine length most bergers like to stuffed in.
I also tried Retumbo and it did do very well in the 243 however a couple others not so much so I went back to H1000 to keep things simple.
I also have a custom 243 with a 1:8 28" Brux that H1000 will push a 105 berger out of at 3150 with amazing accuracy.
I will say this with 47.5 grains and LRM primmer is started to show some pressure sighns I went back to standard LR sighns went away and in further testing it did not increase velocity enough with LRM to even speak of and accuracy suffred slightly now this was just my experience.
it looks to me that your group could be tighten quiet easly play with seating depth for we all know bergers are very sensitive to it but looks like your on a good track
I love the 243 and H1000 and it sure puts the deer and antelope down with that little Berger in my neck of the woods

Re: H1000 in a .243 with 87gr Berger VLD's

Yeah, that group could have been tightened up a lot (It measured 2.25" at 200 which is just over moa). Most of that was me . It's amazingly difficult to not flinch when it sounds like a war is going on just beside you LOL. I'll take my shooting bags out next time, and do a better job of trying to get a good group at 100. That should help a lot. I agree that I do need to play with seating depths too. Luckly with my magazine, I have plenty of room to jam these bergers if I need to. One thing I noticed is that the rifle recoil is different with H1000 compared to the factory loads I have been shooting. It's hard to describe, but it feels more like a push rather than a kick. The recoil is a lot more predictable. I can stay on target after each shot which I really like. I noticed the same thing with my 7mm. We shot a bunch of factory ammo in my dads 30-06's and they all kick like a mule. 30 shots out of those 30-06's and my shoulder was sore. I can shoot my 7mm all day without fear of the recoil. Once I get a custom barrel on it and a brake, it's going to be absolutely wonderful to shoot.

Re: H1000 in a .243 with 87gr Berger VLD's

I will agree with you on the recoil the lower pressure powder seems to give more of a roll opposed to a snap IMO make it makes it more comfortable to shoot
Better Velocity great accuracy better barrel life what's not to like!
Now if I could find couple 8lbs jugs I would be happy happy happy!
I'm not knocking the ol faithfull 4350 4064 Varget there proven just feel H1000 had some strong benefits to it in more than the big boomers
