Slow loads for 7-08?

[muleman]

I want to shoot the 175ABLR and the 195 Berger at around 1800fps into jugs. I want to simulate impact at 1000+ yards. Q/L says full loads BMG50 or H869 will do that at about 27kpsi. Is that safe? Will it work? I'm concerned they'll just keyhole. What do you think?

I would use H4895...

I am also looking into using Unique pistol powder.

I'd be pretty scared of trying that ultra slow powder. And I'd love to tell you exactly why but I can't! It just seems like if it was a good way to produce slow loads you'd see a lot more of the data out there..... instead the trend is towards bulky faster burn.

Inconsistent ignition is the likely result, with the possibility of an uneven curve with a nasty spike.

H4895 or Trail Boss would be my picks.

Thanks guys. Hogdon says H4895 is the best to use as a reduced load. They say 60% of a max load of a listed cartridge will be a good starting point. They list 38.5 as the max for a 175gr Partition. So 23.1gr is my starting point. 24gr supposedly will give me 1800fps. I was kind of leary about a 60% fill. I'll try a few and see how they chrono out.

Looking forward to the results of your expansion test.

Scott,

H4895 is the right powder choice.

I did a 1000 yard simulation with the 7mm 150 gr ABLR and 168 gr ABLR
bullets shot from my TC Contender in 7-30 Waters with a 14" barrel.

I loaded a few ELD-x's yesterday for jug testing . one at 1800 fps , one at 2300 FPS , and one at 2800 FPS . I used H4895 and the 60% rule to get the 1800 FPS . I used H4895 for the mid load too . I'm saving water jugs now .

 

[SJB358]

Nice. Looking forward to the results Jim.

I think Jake has another one of the ELD X's at 2700'ish coming as well.

that's great , maybe we will get a few different calibers tested . I think ridgerunner is going to test the 7mm's too .

 

[Ridgerunner665]

I am...but they're the match bullets I believe.

ok , I'm still interested in seeing how they hold up .

 

[SJB358]

Wondering if the match bullets will hold up better, similar to the Berger.

that's my thoughts too Scotty .

I knew we were on the same track.

Why do you want to use such heavy bullets in a 7mm-08?

To test them for expansion at longer ranges from a larger rifle at longer range.

HA!! Wasn't sure what that meant at first!

 

[muleman]

Made it out to the range today and shot the 7-08 loaded down 26gr H4895 and 175ABLRs. They chrono'd at 1663fps and shot 1/2" in groups . Recoil was easy and they were fun to shoot. The 28 will be out at 1200+ yds at that velocity. I also tried the 195gr Berger but it wasn't stable and I ended up with a keyholed shotgun Pattern. Almost ready for the jugs.
