Recommended bullets for 308 with 1:14 twist, subsonic!

[andym79]

Hi guys, apologises that this thread is very much like my last, but I figured I might receive a better response if I worded the question better.

I want to use a load for plinking and casual target shooting at 200 yards, so expansion characteristics are of no concern only accuracy, the barrel is a 1:14" 23".

What bullets would you recommend shooting in it that are likely to be stabilised and remain so out to the 200 yard mark even though they are subsonic loads?

I am guessing a round nose profile may help and probably something lighter than 170, maybe 150?

Thanks

length not weight.
use more drive band length to compact the boolit.

Do you mean something like this?

It would be hard to go wrong with the Lyman design (or clones) of the 311041. Depending on the mould, they come out between 170 grains and 180 grains. They're rather stumpy as the design is for the 30/30 so they should do just fine in your 1 in 14" twist at lower velocities.

If the 170 grainers don't stabilize at longer ranges, and you are really down in the cellar velocity wise, perhaps the RCBS 150 grain design would be a good choice if you want to shoot to 200 yards.

My squib loads (subsonic) usually use a plain base bullet. I've had good luck with any of the 115 grain 32/20 designs when fired right at 1,100 fps from any number of 30 calibre rifles from Krags to Springfields. Great bullets for rabbits and vermin and they hold well on steel at 200 yards. The RCBS 30-115 bullet is also very good, but is a gas check design. I usually shoot it at higher velocities and on vermin it is just perfect and is a real killer as well as being accurate. I once shot my limit of 10 cottontail rabbits with 11 shots from a 1903A3 Springfield at ranges between 50 and 70 yards using this load. Jack rabbits don't stand a chance at even longer ranges.

I'm not sure what powders you have down under, but Bullseye powder has always been a good choice for the really light loads and lately I've found Tightgroup to work quite well too. To keep from shrinking your case with very light loads, drill out your flash hole a bit so that the high pressure in the primer pocket is equalized with the lower pressure in the case hull.

Be prepared to add some 8 to 10 MOA to your sight setting to zero at 100 yards with the really light loads.

Oh, and yes. The bullet you posted a photo of is probably just what the doctor and Run5Rnun ordered.

Mid weight and lower velocity.

Might be tough. I have never been able to get a 30-30 w 1-12 twist to shoot much more than 150gr subsonic.

[runfiverun]

if you fill in some of those lube grooves with lead you'll add more weight and still have the same length.

Out of my Savage 340 30-30(12"twist) both 311466(no CG) and 311410 PB are sub 2moa at 1100 fps with Bullseye. Very consistent 1-1.5" 100yd groups with a Weaver K2.5 scope.

So you think a 170 won't work?

If i must I think I could go up to 1400fps!
