Quick question, anyone got a riflling twist calculator table or program handy? My search has proved not so good....

My 7mm08 Rem has a twist of 1 in 8.5" and is great for heavy for caliber bullets like 168gns, but I want to try some 130's and think that the twist may be a little fast to stabalise them.

Any ideas or does anyone have the answer?

Ta!

Dunno if this helps you Sim

I like this one by Tom Myers.

Thanks chaps, it looks like 130s will be too light in a 1 in 8.5" twist.....

Sim if thats the case then have you tried going up the way to 175s ?, sporting services have some SMKs in 7mm and it says specifically for 8.5 bbls

Trouble is, I'd be struggling to make 2400fps with 175's...... In real terms, I'm just over that with the 168's. I like the idea of 130's at over 2900, so I may give some 150's a go.

But, if anyone has a few 130gn sierra matchkings kicking about for me to try......

If you still need one I have one in excel which is only 18kb, so I could e-mail you a copy?

I have a remmy model 7 in 7mm08. it has a 1 in 8.5 twist barrel. it's favourite is hornadys 139 gr interlock. i shoots sierra120s to about 2 inches at 100 yards. but the interlocks cloverleaf.
