6,5x68s reloading data!

[Andriux]

Thank you all. For your thoughts. Today it was perfect with 100gr hornady a- max; 70gr vihtavuri N160; COL:83.6. I still don't know the speed. But it shoots very good.

Thank's

Best regards from Lithuania!

The 6.5 x 68 by its' very nature is a speedy little rascal. If 129 Gr. bullets shot well I think I'd try something heavier like a 140 Gr. I wanted to use a 140 GMX in my 6.5 x 55 Swedish Mauser. The trouble was I couldn't find any, I called Hornady and asked their Ballistics Technician about it. He told me that they couldn't get the 140 Gr. GMX to stabilize. Mind you this was at 2775 FPS. I suspect that you are running into the same issue with your 6.5 x 68 and its' higher velocities with the 120 Gr. I really like the 140 Gr. bullets in this caliber so I went "old school" Nosler Partitions for deer size animals and Swift A Frames. Since then accuracy and bullet performance has never been an issue. BTW I'd love to get my hands on a 6.5 x 68. I've never seen one on this side of the ocean.

Shootist43, me too, that is why I started a thread in regards to the barrel life of the 6.5x68S..meanwhile there was a set of reloading dies for sale on the forum last week..so I jumped at the chance to buy it...I now need a reamer ..already have a lot of 6.5X68S brass , courtesy from my good friend HWL...I believe a Shilen barrel may be in the order of the day??
So I now will have a 8x68S hunting rifle as well as a 6.5x68S hunting rifle build on Mauser actions..it will be hunting rifles and not long range shooting rifles..

Members, what twist rate will be optimum function in the 6.5x68S barrel with a 28" inch length ???

gert,
for up to and including 140 gn bullets, 1 turn in 8" would suit.
there are now some very low drag 6.5 mm bullets coming out that will require a 7.5" or even a 7" twist.
bullet length not barrel length is what matters.

Great, it would be nice to use bullets that will compliment this type of re-loading and shooting..
