3 Groove Barrel ?

Has anyone had any accuracy problems with them? Do they shoot as well as a 6 groove barrel? Do you gain more velocity? Do they foul less?

IMO they are just as accurate as a 6 groove barrel, foul less, and last longer.I believe they offer slight velocity gains too.

Re: 3 Groove Barrel ?

I have used 3 groove Lilja barrels with great results, they are as accurate a barrel as I have shot in my custom rifles.

Only thing I will say is that in some of my 1-8 twist barrels in 22 and 6mm calibers, they seem to tear bullets apart in rounds like the 22-6mm AI or 6mm-284 when using the match type VLD bullets such as the Berger bullets and the A-Max bullets at less them top velocities.

The Sierra Mks handle more speed.

I have talked with many shooters who have fast twist small caliber rifles with big cases that shoot these bullets great at much hogher speeds then the 3 groove will.

The only difference inthese set ups is in teh number of rifling so I assume this effect bullet integrity to some degree.

If your going to built a fast twist, high velocity small bore rifle for use with the VLD bullets, I would go with a 5 groove or 6 groove barrel.

With stouter bullets they perform amazingly well but on the thin jacketed bullets they seem to tear bullets apart faster then a 6 groove.

Good Shooting!!

Re: 3 Groove Barrel ?

Thanks for the info guys. I was thinking of using a 3 groove 12 twist for another 375 H&H and a 3 groove 10 twist for a 300 win mag. In the 375 I would just be using hunting bullets like the 260 Accubond and X bullets. For the 300 win I would be using Hunting and match bullets. The main reason I am building the 300 win is to use the 200 grain Accubond. I was told that a 3 groove barrel will give you about 100 FPS faster then a 6 groove in equal barrel lengths. Is this true? If so with a 28 inch pipe on a 300 win you should be able to push that 200 accubond around the 3100 fps mark which would be a nice long range setup.

Re: 3 Groove Barrel ?

Fifty, Your helpful comments about the the 3 groove barrels and VLD bullets in 224's, just made me decide to order a Krieger rather than a Lilja barrel for my next .224 Clark.

Once Richard Graves 85 grain and 85+ grain ULD bullets arrive, I will measure their length, and then decide whether to use a 1 in 7.7 inch, or 1 in 7.0 inch twist Krieger Barrel.

I have heard several reports that the 7.0 twist can cause the 80 grain VLD bullets from Berger and JLK to come apart, but they will often work OK in the 7.7 twist. The 80 grain Sierra HPBT usually seems to shoot OK with either twist.

It will be interesting to see whether the 130 and 140 .257 cal bullets he is sending me will stabilise in the 1 in 10 twist barrel of my 25/06 AI. The surprise report of them stabilising in a 25/06 has given me a little encouragement. Regards, Brian.

Re: 3 Groove Barrel ?

If you are considering a 5 groove check out the Mike Rock 5 R barrels.

Re: 3 Groove Barrel ?

Demarpoint, I am aware that Mike Rock barrels have an excellent reputation, but according to an acquaintance, they are reluctant to export barrels.

As I live in Australia, it is simply a matter of choosing from those barrel makers who do export. Over the last 35 years, I have used numerous Shilen, about 2 Douglas, and 1 Ackley. A local rifle club imports Krieger barrels, so that is the reason, I was seriously considering their barrel.

Maddco, who many consider to be Australia's best barrel maker, do not make a faster twist than 1 in 8 in 224 calibre. Regards, Brian.
