Which 6.5 caliber ??? need your experiences.

OK folks, this may be a big question, hope you all can help. I am having my first custom rifle made. I have chosen the 6.5 caliber, and ordered a Krieger #3 contour 26" 1:8 twist barrel. Now I have to decide on which case. My gunsmith is recommending the 6.5-270. I would like to use this for deer and elk hunting so I am looking at shooting 130gr or heavier bullets. Please give me input on your experiences with the different 6.5 cases, ie... comparing 6.5-06, 6.5-270, (maybe improved versions of these), 6.5 Gibbs, 6.5-280? any other suggestions? I have been going through "cartridges of the world" and the data is confusing if correct, showing less case capacity and lower velocities in the improved versions in some cases. This rifle will have a standard action, and will be used predominately in Washington state and hopefully, Montana. Thanks.

A 6.5-284 would be nice.

I pondered a 6.5 -280AI ?

I'm a greenhorn w/ wildcats and reamer specs etc. but i wondered if you could take the nosler 280 AI brass and neck it down to 6.5.
The 40* shoulder would already be in place so maybe if you could just neck it to .264 it would be a nice and easy process .

6.5 gibbs would be a nice/neat round also.

Oh sorry i see i'm not helping here ....Mike

6.5 Stw

My choice would be a 6.5 STW. As they say " Go big or go home!".

The ones you mentioned are all really based off the same case and will be more or less the same. The 284 case will also be close with a shorter case and possibly more room to seat bullets depending on what action/stock you are using. It really depends on what you want to shoot and how far. There are lots of other choices also, the 6.5X47, 260, 260 improved, 6.5 WSM or WSSM, 6.5 x 55, 6.5BR are all fairly popular. It really depends on your plans and how much case work you want and if your willing to change bolt face sizes. If your looking in the 06 case capacity range the 284 is hard to beat with brass available and a very good track record. Pick a bullet you want to shoot, speed you want and that will help you pick a case size. It might also be a cost consideration with what reamer your smith has on hand. If you decide(or pass on) what your shooting, how far and how many rounds you want your barrel to last you can get more specific info. just my .00002 cents

You might consider actually going with a non-wildcat cartridge, the 264 Win Mag. I'm not totally sure the 26" barrel can get the full potential out of this cartridge but it should be comparable to the 6.5-284 and a little slower than the STW (but the STW would benefit even more from a longer barrel).

I have a hunting rifle in 6.5x284 and absolutely love it. I shoot mostly 140 AMAX bullets out of and it is very accurate. Recoil is mild and just fun to shoot. I use Lapua brass. The Lapua brass is very consistant, a little expensive, but will last for many firings. Good dies are readily available and would have more appeal IMO than some of the other wildcats. I also have a nice 6.5 06 AI in a Mauser action. It would be more difficult to trade or sell.

Going with the comment "Go Big or Go Home", I would have to recommend my 6.5mm Allen Magnum based on the 338 RUM case .

My wifes 1K rifle will throw the 142 gr SMKs out at 3550 fps with relatively comfortable loads and do so with 1/2 moa accuracy.

Just need to keep the barrel cool.

Probably not what your looking for. She can be a bit finicky and very limited in powder selection. Still if your looking for shear HP, hard to beat!!! A 142 gr SMK loaded to +3500 fps is a pretty flat shooting round.

If you want a high volume shooter, I would not recommend it!!!
