Gday fellas,
late evening at home on the couch just wanted to strike up conversation on this Forum regarding the 7mm 08, The loads, velocitys and Sight in @ 100m Point of Impact, and what purpose the "little Seven" serves you.
I'm loading 139gr hornady interlocks an AR2208 for around 2700fps in a Kimber 84m.
id previously been using 150gr Federal Factory round an look forward to the reloading side of the 708, once I find the right projectile for thee job at hand.
Keen to hear more
Thanks
Rees
140g Nosler Ballistic Tip @ 2925fps
100 yrd zero
Dial up scope
1000ft/lb of energy @ 600+ yrds
I'm using 110gr TTSX H335 powder for about 3000fps from an 18" barrel. Close range to about 300yds.
My go to load for the past five years was the 140gr BT @2750fps - killed like lightning. Now I'm playing with the 162gr Amax @2640fps...just because!
howdy.
I went an shot in 100- 200 and 300m with these 139gr loads.
my trajectory was
+2
-1.5
- 15
which I estimate a velocity of around 2700fps
good times, not much recoil in the light gun, not a bad bark either, just going to test on some game this weekend hopefully, sit an wait for dog tucker
cheers

I load 120Bt in front of 2206h, the gun never leaves the gun room, I have a 7mmRM that I have for longer distances and always decide to take that instead. So I can't talk about how she shoots as I never bother shooting her, the big boy is only a couple of kilo heavier for much more capability
Give it to me I'll shoot it
120 grn NBT @ 3k, 18" barrel. CFE223 powder. Kills well. Have shot deer out to 420yards.
The 120 has the same jacket thickness as the 140 so it penetrates well.
Do you mean accubond or partition Tahr? Pretty impressive whichever.

what I have learnt though is the 7mm08 is that little bit slower from the get go and at 200-300-400 maybe even 500m the bullet is goin slow enough to penetrate and expand without violent expansion and shallow wounds. same kind of theory as the big bullet moving in slow motion pushes in further. just a few more steps away.
cheers
570mm barrel 140gr NBT G7=0.214 860m/s 48mm bore to sight
Zero at 100m
Trajectory at 1000m ASL and 15 deg C
25m -1.2 mRad (-3cm )
50m -0.1
100m zero
150m -0.2
200m -0.6
300m -1.3 11m / 0.1 mRad click; +0.3 @ 30deg slope; rough guide wind @5 m/s full value 0.7 mRad
400m -2.2
500m -3.3 8m / 0.1 mRad click; +0.6 @ 30deg slope
after that you're on your own, mate.
The trajectory is within 1 cm of the sight line from 40m to 130m. THAT's a point blank range.
300m would be about my limit on animals in good conditions.
Excellent knockdown within that.
Trajectory verified on paper and plenty of gongs up to 500m but kinetic energy is getting down out there.
Slower compared to what? A magnum?Quote:

Maybe your cousin needs to work on his shot placement rather than blaming the bullet?
I have considered a different bullet for this rifle on a number of occasions but I still can't come up a good enough reason to do so.
Hmmm - more likely target species. Sambar is a whole different ball game than reds or japs.
For sure. It was a consideration I thought would be worth mentioning but I have no experience on Sambar so did not.Quote:

The hornadys, which I am picking out of Dirt , don't seem to be holding up too well, Dirt being harder than any Sambar deer ,
No beginner to killin Sambar, just a beginner to the 7mm08 ....
Slower in comparison to the +2900 Gang, in which over that Speed ive found Cup an Core projectiles Don't penetrate very well nor hold together. just my findings over the years.
i'll never touch a BT for our big deer.
Your 'Lazy ' Load is quicker than my go to Kimber load albeit by 70fps...
.
cheers
For the 7mm-08 I have yet to see a bullet with more put down capability than the Barnes TSX. I could get the 120TSX to 3100fps using RL15 and think they may be your Sambar solution.Quote:

personally not a Mono fan either, was gifted a lot of Vortx factoy 270 stuff, so am using that to 400 no dramas. once there gone, I don't see replacing them.
cup an Core, bonded if needed , just me personally.
the 120tsx would be a good choice for mono fans on Sambar though, providing you can push them at 3100..
an all time Favourite is an Accubond, proberly 140gr in 7m08 knowing il proberly be only at around 2700 range from the muzzle.
Interlocks though.... look to act like a Super X SP...
With the Hornady 139gr bullet, choose the spire point over the boat tail version - holds together and expands well. Don't know the length of your Kimber barrel but you should be able to comfortably get 2,800 fps from a 20" barrel in 7 mm/08.
Similar here, 120NBT @ 3080 from a 22" barrel. Only shot one deer with it so far (170yds) but it died quickly enough and didn't go far.Quote:

Ive just started playing with a 120 NBT load in an old Mod 7 7mm08 that ive just had bushpig'd to 15", using a book max load of CFE223 i have them going 2900 fps, and accuracy is looking promising.Quote:

poor penetration an jacket core seperations were all too common in the 5 sambar ive shot this week with them... not good in my book.
better luck with the Woodleighs at around 2650-2700 if lucky.
Hi mate! geez this is good advice, but I have 70 loaded up haha!Quote:

I'm around 22 inch barrel. low charge , appx 2700.
