I wondered about that myself. I kiss the groung every time I find a load that will shoot 1.5 inches at 200 yards.

...Shooting Sierra and Speer 140 grain...




Hey Bill, I've checked this thread a couple of times now and am a bit surprised no one mentioned your rifle might not like 140gr bullets. Some rifles just don't shoot some weights as well as other weights. So, you might want to try another weight like 130gr, 145gr or 150gr.

Nothing at all wrong with your original powders. I've found the H-414 you mentioned to be the very best powder in my 7mm-08 with bullets from 115gr-150gr.

...

But, then we get to the heart of the matter when you said:

Quote:

...A Bolt ...holds about 1 1/2" at 200 yards.




Perhaps some of the fine folks have "mis-read" your 1 1/2" group at a distance of 200 yards as 100yds.

What size groups do you think that you and the A-Bolt should be shooting at 200yds? < !--color-->

I'll go out on a limb(about 1 1/2" off the ground at 200yds) and say that you may never shoot groups better than that "with your A-Bolt", irregardless of what case/primer/powder/bullet combination you choose to try. That is an outstanding rifle and load combination as it is to do that well.

Congratulations on the fine shooting.

Thanks Jay and all for the suggestions. I'm going to try some RE 15 and Varget and give it another go. Sorry about being blockheaded over the H1000 but just could not understand why it worked in the 6.5 x 55 and would not work in the 7-08. Both are great cartridges arn't they. Like shooting 20 guage. And Varget and RE15 are both great powders. Thanks, again. Bill.

Has anyone tried H1000 in the 7mm-08? I have had a hard time getting an A Bolt to group under and inch. Best powder todate is 4895 and it holds about 1 1/2" at 200 yards. Tried 4831, H414, IMR 4350, H 4350 etc. Shooting Sierra and Speer 140 grain. I recently finished loading for a CG63 Mauser in 6.5 x 55. The folks at Hornady suggested H1000 saying some have had good success. Well it worked great in the 6.5 x 55. It is an honest 1/2 - 3/4" rifle with about 49 grains of H1000 even with the standard Soderin receiver sight. My quesion is why not use H1000 in the 7-08. Case capacity is within 6% of the Swede cartridge and so I don't know why it would not work. Has anyone ever tried it?? Thanks, Bill.

there is no way you can get enough h1000 into a 7-08 case to make any decent speeds...I'd try Varget, RL15, 4350's, or RL19, that is as slower burning as I'd go...I use h1000 in my 260 (basically same case capacity as the 6.5 swede) with decent results with 140 gr. bullets. If h1000 was to be useful in a 7-08, I'd think it would be with 175 gr. bullets, not 140-145 gr...

I think I'd take a closer look at that A bolt. Screws, inletting, scope mounts and such. With some of the stuff you've been using, it should be doing better than 1.5 inches.

I agree Beemanbee. I've had it out of the stock a half dozen times and everything looks fine. Actually was pretty impressed with Brownings bedding and barrel clearance. Might be the scope...using a Leu 3x9. Could change that I guess. Using good bench practices so I'm compfortable there. As stock the barrel was a horrific fouler. For every shot fired I spent 15 minutes getting the copper out. Took it through Holland's pressure lapping and found incredable improvement in smoothness. Zero fouling at this time. Maybe its in the crown or maybe in the action lug engagement. Don't know for sure.

Bill,
Don't give up on the Abolt 7mm08. I had a Composite Stalker that shot 140gr Ballistic tips with 43gr. Varget into 3/4 in groups. I bought my father a Micro Hunter in 7mm08 that will shoot the same load into 1/2in groups or less. This past fall, when I tested his rifle for deer season, he shot a 3 shot group that measured .368. I told him maybe I should use his rifle for benchrest matches . I just bought a Stainless Stalker in 7mm08. Using the same load, I fired 3 5-shot groups that averaged .695in. All that to say this, before you resort to drastic measures, TRY VARGET!! It's been a great powder for me. By the way, my seating depth was about .020 clearance on the magazine from tip.

Bill, I can't believe Bob and or Doug told you to use H1000 for the 708, they always told me Varget or something in that burn range, RE15 is by far the best powder for the 708 for 140-150gr. bullets, Varget or N140 being the 2nd, 38-39grs. RE15 shoots very well with 150MKs,(under 1/2") Varget didn't work well with that bullet, 39.5grs. of Varget worked very well with Nosler 150gr. BTs,(under 1/2") to give you an example, RE15 is the accuracy load for 140 & 150gr. in the Sierra manual, try it, you won't be disappointed. Jay

Hodgdon did not recommend H1000 for the 7-08. They suggested it for the 6.5 x 55 and they were right. My Swede is an honest 1/2 t 3/4" shooter / 5 shots at 100 yards with Receiver sights. And I find this incredable accuracy for a 100+ year old action (CG63). The initial question that I raised was "why does it shoot so will in the 6.5 but is not recommended for the 7-08. Case capacity is only 6% different and bullet weight is the same. EVERYTHING I have read indicates that H1000 does not work in small cases. It worked in my 6.5 and it was recommended by Hodgdon for the 6.5. But has anyone tried it in the 7-08?? Thanks, Bill.

Bill, H1000 isn't recommended for the 708 because, to quote my Hodgdon manual, "H1000, This very slow burning Extreme Extruded powder is perfect for highly overbored magnums like the 7mm Remington Magnum, 7mmSTW, and the 30-378 Weatherby" As you know the 7mm08 isn't a overbored magnum cartridge, and that's why nobody uses it in the 708, Jay
