30 Gibbs shoots

Got my rifle back from the gunsmith last week and I have fireformed and shot some loads. The initial results are excellent.

With fireformed Fed 30-06 brass, I just shot some molied 165gr Hornady SST bullets into a ragged hole at 100yds. The powder was H4831SC (64gr) and CCI BR2 primers. The throat has been cut so that my bullets just engrave the rifling when chambered (still feed from the magazine).

Will chronograph soon but should be in the WSM/win mag range. Rifle has a 26" barrel. Recoil is stiff and a muzzle brake will be added soon. Will try some long range shooting as time allows.

For someone thinking about the WSM but because of budget can't do it, I would recommend the 30 Gibbs as an alternative. Any 30-06 rifle can be rechambered for this round and it should give the same performance for the cost of rechambering (about $75 to 100).

Get a neck sizer or maybe a Lee Collet 300 Win mag die and you are set. The reg. 30-06 or 308 bullet seater will work. When the brass gets too big to fit, throw it away. After three full loads, the brass looks great. A tight chamber and sharp shoulder are keeping the brass from stretching or bulging.

My new "skinny long" magnum...

    Hi Jerry,
    I will be interested in your chronograph results.
    About 15 years ago I chronographed a .30 Gibbs, and the velocities were only slightly higher than a regular 06. I realize that it might have been the loads the guy used, but I have always doubted the claimed results of the Gibbs cartridges.

    Please let us know your chronograph results.

    Thanks,
    Jerry

    Don't ever "doubt" the claims of the Gibbs line of cartridges until you own one and load for it at max.

    I have two 30 Gibbs, a 25 Gibbs and a 6.5 Gibbs. Just sold another 6.5 Gibbs to a fellow here on the forum.

    With 30" barrels the 30 Gibbs and 190 gr bullets are right there with the 300 Win Mag with 190s.

    The 6.5 is right there with a 264 Mag both with 140 gr bullets.

    The 25 Gibbs is right there with the 257 Weatherby.

    Ray Romain has all the Gibbs reamers and we use the 270 case as the base instead of the 30/06 case.
    It gives a .050" longer neck and a great cartridge to shoot.
    It has the 35 degree shoulder which works very well.

    You don't have to go to some of the smaller mags when you have a Gibbs Gun. Good brass is available also. Norma makes 270 brass which is ideal for the 6.5 and 25 Gibbs.

    Have had several Gibbs guns ovcer the years and like them alot.

    Send me an Email and I'll give you some loads for the 30 Gibbs. Mine really likes the 168 and 190 gr SMK bullets. The 190 gr load gets to 1000 yds in a hell of a hurry.

    Darryl,
    I was thinking about a 6.5-06 but your Gibbs sounds interesting. Could I get some more info please? I have an Obermeyer 5R barrel with a 1 in 8.5" twist that will finish at 27" just waiting to be put together. Thank you for your time.

    The 30" barrels seems to really make the Gibbs shine.

    The 6.5/06 is a dandy cartridge too and I would consider looking further at that one unless you like to fireform cases like you will have to do with the 6.5 Gibbs chamber.
    Some people don't like doing this, but others don't mind.

    The Gibbs cartridge will hold up to 9 more grains of powder over the standard case depending on the brass you use.

    It is a serious improvement over the standard and will perform quite well.

    For normal use and shooting with the 6.5 bore, the 6.5/06 is a very good one. If your after more velocity, then the Gibbs is the answer. The 6.5 Gibbs and 140 gr or 142 gr Bullets with the 8 or 8.5 twist will amaze you.

    Ray Romain (Gunsmith) has a 6.5/270 reamer that is even better then the standard 6.5/06. It will give a .050" longer neck. He also has the 6.5 Gibbs reamer on the 270 case.

    With up to 9 more grains of powder capacity, the Gibbs is a dandy and like I mentioned above, will give you added velocity and the wear factor of the barrel, is very good.

    Ray's phone number is---814-265-1948 if you want to call him.

    Darryl,
    Thanks for the info. I think I will call Ray next week. Also, why do you say that the 6.5 on the 270 is better? Does the 0.050 longer neck really help that much? I hope I don't sound too ignorant but I don't understand the benefit of a longer neck. The use of better brass without having to trim 0.050 off sounds good though. Do you have to have custom dies for the 6.5-270 or can you modify a set of 6.5-06 dies?
    As always, you have been a great help,thanks.
    Wayne
