.223 in 1 in 8 twist


Recommended Posts

I recently took delivery of a southern guns AR15 with a krieger barrel amongst other modifications, I'm new to this calibre and wanted a 1 in 9 twist but could only get a 1 in 8 due to delays in production... it had been on order since the beginning of the year. :good:

 

my question is can I use ballistic tips through this, if so does anyone have any suggestions, I have currently some 77 gn serria match grade hollows.. although they don't look very hollow to me, up until now.. due to the weather i have just been bedding it in with some brazillian 5.56 loads :good: as instructed :/

 

I'm told it won't or is unlikely to settle the remmy 55 gn vmax load.. infact there is a strong possibillity they will just vapourise on exiting the barrel. :/

 

I was after a fragile round for foxing with and shooting very long range rabbits, I'm more comfortable using ballistic tips.. I'm quite happyy to learn and go down the route of homeloads if I have to, but just wondered if anyone else has any experience of this rifle and or configurations with a similiar barrel twist?

Home loading is the way forward :good: You can get some 64grn factory ammo which will get you under an inch but if you want the best ...reload your own :/:/

I use 69grn serria matchking BTHP for everything from rabbit to fox to paper and had no complaints from any yet :D:D

Get a pic up :/ always good to see another black rifle :D:D

John,

 

I take it you have sorted the Tikka then, what was the problem?

 

Changed the scope to one with a chunkier reticle, the ret on the NF was too fine for my eye I can see the Viper ret much better :/ . Also changed the cleaning regime, now all she gets is two soaked KG12 patches then 2-3 dry. Some will say that's too little (or too much :good: ) but the cleaning and chunkier ret seem to have made a difference so far :good:

 

I'm begining to feel the happiness again :/

I heard the vaporsing story from someone I trust, apparently this <can> happen with bullets in the 45grn region and driven quickly.

 

I don't have an AR but a mate of mine has a 1:9 and that shoots very well with AE 50grn hollow points.

 

I will dig out a picture from the weekend for SL...

I appreciate all these replys... I will go and get some 55 gn vmax and put them through and see if it groups.

 

Its a round I'm very keen to use

 

As for a picture.. :good: I haven't really had time to photograph it properly but will when i get a chance this week,

 

meanwhile heres one from the mobile phone :good: ,

 

just the barrel and A.R.M.S. rail, now its almost bedded in I will slot on the can, also waiting for proper scope rings 34mm for the Schmidt PM2 thats going to sit on the top! :/

i have just bought a new mannlicher pro mountain does ant body know the twist rate for this rifle s i cant seem to find out any where

Even their own site doesn't quote it :good:

I would ring The Sportsman, they are the UK dealers I believe.

 

I think I would have asked the question before buying it, but then I don't what the circumstances were . . .

if its a .223 then it will be 1in9 :good:

 

 

mine liked factory hornady 55gr v-max and really liked fairly hot loaded 40gr v-max home loads so i think a 1in8 barrel should easily cope with 55gr's although i might have just been lucky.

I use 50 grain bullets in my t3 223 are they to light for a 1:8 twist barrel?Would a 55 grainer work better anybody know??? :good:

 

What groups are you getting? My last three were inch with Vmax, and 3/4" and inch with Accutip, both 55grain. If you're happy with what your getting though... You could always buy a box and shoot it, no need to adjust scope even, just see how they group.

Twist rates and ballistics is a science .My .223 is 1 in 12 but you can bet your botom dollar that if it was 1 in 9 I would still try 50 grn through it because a faster twist rate and heavier bullet combination is.nt always the case .

 

When you witness a .243 with a 1 in 10 twist shoot Homeload 65 grn ballistic tip as well as Factory 105 grn Sp's with eqaul amount of accuracy at 100yds then the theory is kind of blown out of the water IMO .

 

 

A lighter grain bullet in a fast twist rate giving eratic groups might be down to the quality of the factory ammo and not necessarily down to combination .

 

 

The biggest advantage about Homeloading is the fact you can set the seating depth of the round to interact with the lans of ther rifling .

Having seen a 22/250 shooting Hornady factory group like a shotgun at 100 yds then compared to a homeload round for the same rifle whereby this bullet sat a further 3/5mm out of the casing compared to the factory version to just kiss the lands . :good:
