Lineotype and gain twist rifling questin

[Rapidrob]

6.5, .266, 150 grain gas check bullet made from Linotype. How fast can it be pushed in a Carcano '91 with Gain Twist Rifling?

Start low and work up. Your target and barrel will tell you.

For hunting or paper punching? 264 dia bullets or boolits have not been kind to me. Linotype is an expensive alloy for paper. I have used it in other caliber for high speed varmint rounds.

I have tried 150gn .269 G/C bullets at 11.8 BHN and 20.9 BHN at 1500fps in my M91 Carcano and the softer bullets produce better groups.

I can obtain 3" groups at 100m with the softer alloy and 4"+ with the harder mix.

it'll go as fast as you wanna push it.
you may not hit anything, but you can push it that fast.

alloy is NOT what makes a rifle shoot well nor fast, it's fairly far down the list and depends on the design of the boolit as to the choice of alloy needed.

I was wondering if the gain twist would allow a faster bullet. I plan on shooting the bullets 500 yards and perhaps further.
I have shot cast bullets in competition out to 500 yards on a regular basis. The 6.5 Carcano I have for these bullets has a .265 bore. I could only find at the time I got the rifle a .266 mold and sizing die. There were no .268 molds as yet. I was hoping Linotype would hold up better being a harder alloy. If softer is better I will try that as well.
Steel targets,no paper.
I do a range report if the loads posted work in my rifle.

I took five loads to the range. 200 yards. The rounds sized to .266 worked very well as long as I kept them around 1,800 fps. Faster proved to lead the bore even though they tested at Brin-22 ( gas checked) Rounds were high on target even putting along. I'll need to modify or make a taller front sight.
Thanks for all the good ideas.
