270 Gibbs

panhandlepr1 · Jul 21, 2007

sold my 270 several years ago and have kind of missed it. Would like to have a 270 cal. but maybe something a little different. Everyone seems to I have a 270 or an 06. The 270 AI doesn't seem to show much of a gain and I was wondering about the 270 Gibbs. Does anyone know anything about this round? It looks interesting but can't find any info. Need help!!

panhandlepr1,

The fact that you can't find much data for the 270 Gibbs might be telling you something. :shock: I'm sure its a great round but with limited data, you will really be limited.
If you want something different, consider the 280AI. It can get you 7mmRM performance in a different case. You could also look at the 270 WSM and the 270 Wby if you want to stay with .277 cal bullets.

Just something to think about....

I would also consider the 280AI or maybe the 7m-08AI. I have the 280 and have had a couple of 7m-08's. Both are great cartridges especially for the reloader. The Ackley Improved cartridges are starting to come on strong, I think I see one in my future. Maybe in 22-250AI

Like JD338 said, if you cannot find any data for the Gibbs cartridges, that should tell you something. Most had very short necks as I recall. They were ahead of their time, to be sure, but I am not sure they were all that great.

I CAN tell you that if you want a hot 270, the 270 WSM leaves little to be desired. I probably would not have gone out and bought one as I already had a 25-06 and a 7mm Wby Mag, etc. etc. BUT, I won one in a raffle and the WInchester Model 70 that I wound up with in 270 WSM is a great shooting rifle.

I shoot 140 grain Nosler Partitions 3200 fps from this 24 inch rifle and it groups them into 3/4 of an inch day after day. It also shoots 140 Accubonds well, but I just prefer the Partitions.

The only thing I shot with the AccuBond was a wild hog, but it dropped him in his tracks.

With the Paritition I have shot hogs, black bear, and mule deer. None of them every took another step.

I have not had a chance to try it out yet, but I have a coyote load worked up for it that sends a 90 grain Sierra HP out of the barrel at close to 3700 fps and shoots 1/2 inch groups. This load has worked in 3 such 270 WSM rifles we have tried it in.

I read complaints about the short mags not feeding well, but this Model 70 feeds those short, fat cartridges with no problems. Case life is good, no reloading problems with the fat cases.

Ron,

What powder are you using for the 140 Accubonds?

R Flowers · Jul 22, 2007

I tried a number of powders in the 270 WSM all gave pretty credible results. However, with the Paritions and Accubonds both I got the best results with RL 22 sparked by a Fed 215M primer.

Back in 1991, Wolfe Publishing Co., in Prescott, AZ put out a book known as "Gibb's Cartridges". It has 65 pages of all of Rocky's favorites, including many loads for the Gibb's .270. The book is still around, as I saw a copy of it at a recent gunshow. I've always been interested in "improved" cartridges, that's why I have a copy of this book, along with others, such as the ICL line and the Ackley line.

I've been reading P.O. Ackley's book and he stated and this is a loose translation. "The .270 Winchester while being slightly overbore is an efficient round. All other cartridges require much larger powder charges to get a marginal increase in velocity." I guess that is why there haven't been many wildcats using a .277 bullet make it to commercial production.

I have a 270 Gibbs with a 25 inch barrel, to date my best load has been a 130 grain AccuBond at 3300 fps. If you have any questions about the round I would be happy to tell you.

I have found the 270 Winchester to be as exceptional round when it comes to balancing recoil, powder needed, long and short range performance, exceptional killing power and a very reasonable range of bullets available to select from .... but my hunting has been in the eastern half of the USA. The 270 has stood the test of time better than most in the Eastern USA and apparently in the Western USA as well based on all the reports from experienced Western hunters.

There are many newer rounds on the market now that offer opportunities to play with something new, sell new rifles, ammo, loading equip etc. and stir up heated conversations in the hunt camps and at the beer parties.

I have had a number of rifles over my 50 years of hunting and find that I always tend to pick up the old reliable 270 when I get serious about deer hunting, thus the name 270fan I use on this board.

That being said I am getting a 260 built now. At 67 years old I want to reduce the recoil a bit, still be in the old reliable 270 window of performance and I to want something new to play with for a few years. Have fun with whatever you get.
