Thread: 308 vs 7mm08 all rounder?

Re the short 308 I have been looking into it recently and shooting the speer 165 btsp (0.52bc) @ 2600fps, which isn't that outrageous out of a short bbl with the right powder, gives you just under 1800fps and just under 1100ft lbs at 600yds so really opens up your options if it shoots

Well I'm not a fan of the 308 but if your are looking at short barrel rifles and heavy / larger bodied game at ranges out to say 300 mtrs then a larger hole will be more efficient accelerating a heavy lump of lead in a short barrel.
ie I shoot a 24" barrel 243 and a 20" barrel 358.
The 358 has about done it's chips by 300 mtrs ie 1450 ftlb energy but velocity is under 1800 fps so bullet performance reduces.

16" barrel?

I use these to good effect in an 18inch barrel with cfe223. I only shoot them at 100m so nothing validated. Someone who ought to know said the ,520bc was a bit ambitous and he figured them for ,477

I had no idea I was supposed to wear a dress all this time. What colour?

White, to match those glasses.

Nothing. I'm just a bit fashion challenged. It's not easy figuring out dresses and stuff for the first time.

Yeah I thought they were lower and then got corrected to higher? Still shows 0.52 last I looked which is annoying. Mate has just loaded some to be an all rounder in his 300wsm

Don't see why not. I use to drive the 165gr hpbt gamekings at 2550~ out of a 16" bbl with 2208 so with 2206h, cfe223 etc I reckon it is not outlandish.

Agree totally. A 16in 308 is well suited to the bush but still capable if something pops up on a slip 300yd away. The 280 has it covered for hunting the open country. So the 7mm08 is redundant really

My 2 cents worth as I went down this track couple years ago , ended up with 308 with 20 inch barrel and DPT , I have a small 10 power nightforce scope for reliable dial up , obviously the 308 has its limitations for longer range type shooting but i set a personal limit of 400 so it’s fine , really no difference in Calibres in that set up just personal choice , what ever you choose and after you nailed your first couple animals and gain confidence with it you will be happy with either I’m sure .

708 softer flatter shooting with a bit more projectile choice. 140gr Berger vld good up close and out to 500m. Chopped to 18inch
