Hi Tean,
I have recently had my 7-08 chopped to 18 inches in the hope to turn it into a bush pig..
Looking at building up load for the bush pig and was looking for recommendations on powder would suit this length barrel.
Look forward to your thoughts.
What bullet weight do you want to go with?
140gr Nosler BT with 2208 or 2206H should do well
Was thinking either 120 BT or 140 BT
I'm using 45gr H335 with a 120gr NBT in an 18" barrel. Getting approx 3000fps load to 2.810" base of case to tip of projectile.
140 gr Nosler BT (P/N: 28140) with 41.5 gr of 2208 is working ok for me.
+1 for 2208
Weirdly the 120 NBT is a harder projectile than the 140 NBT. To make the 120 they got the 140 cup and cut it shorter, so the 120 jacket wall is thicker at the tip than the 140 jacket. I've posted a cross section pic of the two on here before. It's on my computer though, and I'm on my phone.
CFE 223 works well for 120Gr and short barrels
2208 for 140Gr or higher

If you can’t get cfe223, blc-2 is the same in my 708 with both 120 and 140. I use 120.
H414, 2208 and 2209 is what I use in 7mm08.
I load for a mates T3 cut back to 18 inches
43 gr AR2209 behind a 120 gr Sierra (#1900) which has been great on (Fallow, big bodied reds, thar) all the way out to 300 mtrs.
I run the same projectile & powder in my Kimber.
As Stug says the 120 gr NBT is a tougher projectile still
I had 2208 in my 18inch tikka running the 140 at 2650 no pressure signs. Great combo, killed well out to 450 which is as far as I ever launched it. Shot into half an inch
Anyone tried the 162eldx out of a 708? Have 2208 and those to load in a mates gun. Will be chasing reds and rusa mostly. Only a 20" bbl
I shoot 162gr ELD-M through a standard barrel tikka (22.5" I think). They do 2550 fps in the load I'm using (41gr 2208). Good groups, I've pegged a couple of deer with them and they seem to kill as good as anything else. All pass throughs so far with reasonable damage. ELD-X would be similar with more expansion I'd expect.Quote:

I zapped a spiker earlier in the year with one, straight through the engine room.Quote:

Much pressure? That is max load according to adiQuote:

Only shot 1 deer with the 120 NBT so far. A heart shot on red spiker at 220yds. Only bones hit were ribs, exit hole showed expansion. Spiker went about 10-15m and then keeled over.Quote:

Probably go one level slower than 2208 for 162's will get better fill volume and better velocity. RL16 or h414 could be worth a crack. Even at 2500 a 162 is going to be good deer medicine out to 500 oddQuote:

Have you tried the 150 ELDX?Quote:

50grn 2209 pushing 120bt
Tack driver, purchased from @Tikka7mm08. All the work was done.
Very effective on animals, my 9yr olds gun so pleasant to shoot. He has shot bull tahr, deer and pigs.
42.2 gns of 2208 out of a 16" barrel gives me 2580 fps using a 140 nosler BT . This has proved a deadly recipe for red deer time and again.

Velocity loss for any calibre is a function of the case capacity to bore size ratio IE the more 'overbore' a cartridge is the more velocity you'll lose per unit of barrel removed. It's not dependent on the powder choice. If Staball gives higher velocities than the other powder choices within safe pressures at 24", it will still be the faster option with a shorter barrel.Quote:

Velocity via a Pro Chrono is 2739 so it's not exactly matching the data.
The load is nice and accurate though so I'm happy.
That's good to know.Quote:

Punches above its weight it's pleasant to shoot.
Just picked up some Staball 6.5 , in the loading manual it is suitable for a raft of calibers, the 7mm08 shows very good velocities. Burn rate is about the same as AR 2209 ( H 4350) so should have plenty of applications, also isn't temp sensitive , has added anti copper fouling in it.
Tried a few loads in my 303 180 gr PPU behind 46 grs of Staball 6.5 and got 2341 fps av (max load is 47.8 grs.) Got some 95 SST loaded to try in the 243 next time I go out.
