Hi Guys,

Well, I've "set my jaw" and plan to wait as long as I need to until these become available here in Edmonton. I'm looking to acquire one in .223, in single shot -right bolt / left port configuration (I just think it's neat) and I'm wondering..."which twist rate should I choose"? This assumes that both advertised 1 in 7" and 1 in 9" twist rates are actually available... So, what'ya think?

Mostly to start with I'll try every "cheap" factory .223 cartridge available, to see if one will yield "minute of gopher", and take it from there. I will undoubtedly load for it, but not right away.

If I plan to use it mostly with 45, 50 and 55 grain bullets I think the 1 in 9" twist is adequate...is this correct?

Is there then any detriment (as far as shooting the light bullets go...) to going with the faster 1 in 7" twist barrel, should I eventually decide to play with heavier bullets?

Thanks, Jeff/1911.

Oh yeah.

1 in 9 would be my opinion for going longer range. If you want shorter range, 1 in 7.

Think I got that right.................

It would be the opposite wouldn't it?

If you're going longer you would need to use heavier bullets which need a faster twist rate to be stabilized.

I think I have read that having too fast a twist rate with light bullets creates certain extreme forces and can hurt accuracy. It also contributes to barrel wear but I think that is more a problem on the really high velocity small calibre rounds, ones over 1000 m/s and such.

I've never heard of 1 in 7 for standard rifles. I thought standard is 1 in 12 and then heavier barrled rifles for higher long range accuracy will use 1 in 9.

Ace,

I too was surprised to see that Savage is offering it in both twist rates...I think if I am mainly going to fire cartridges with bullets in the 45 to 55 grain range - I best stick with the 1 in 9" twist. Just looking for a little confirmation here, from the "boys".

Jeff.
 
IMHO, go 1:9 The heavies are accurate at long distance but they're slower. Using light bullets in a tight twist (1:7) gives sub optimal results and wears the throat faster. I'd love to play with a 1:7, but for most general medium and occasional long distance, you're better off with a 1:9
