this is to the experts.what 7mm cal can i change my 308 too that will b a good performer out to 1000yds.not a 7mm08.not sure if i need a long action to use the 180gr berger hybrids.didnt know if short magnums are short actions.atb swaro
 
Is a 308 that bad at 1000yds ? heres a quote from another forum " I use 44.00 grns varget,175 smk,win cases,fed 210m primer, 2630 fps , average group @ 1000yds is 10.5 inches , I have shot 6 inches group on a calm day, very rare at the range I shoot at!"

Can you get those on a short action?

Be a bit of a tight squeeze. I had a look at 6.5x284 on my 7mm-08 predator action, it just to say extracted with the 140gn bullets but only just. They certainly didn't fit in the mag.. I ended up going for a long action donor rifle for the 6.5x284 to give me plenty of space. I think with the 7mm high BC bullets, you wouldn't stand a chance in a short action. Not so sure about the 7SAUM or 7WSM.. but imagine either a new bolt would be required or a bit of engineering required on the old one.

PS: Im no expert..

yes thats pretty much sums it up for the short action


i m shooting the 6.5-284 out of a no4 sako 75 action with 140 and its ok but my .284's are both long actions the shehane is on a bat mb action and the .284 straight (which is now up for sale) is on a barnard s
 
The Tikka m55 will take a case and bullet length of nearly 3" and go in the magazine,ive got a 257 ackley that i seat out to 2.95 and beyond...C
 
Higher the bc, better the accuracy at long range apparently, in theory the 6.5 06 I am having made should **** all over my 308 at 1000yds
 
yes bewsher u r cock on.if my 6.5 06 has 3 to 4 moa less winddrift at 1000yds in 10mph wind than my 308 i should b way better.elevation is the easier of the 2.ive loaded some 175gr smks to try next time in my 308.ive used 155gr scenars up to at 1k to good effect..155gr smks out to 600yds
