I rebarrelled a 1938 Mauser 98 with a Brownells 6.5x55 barrel. Nice barrel, but it has a 1:9 twist. I broke it in using factory Lapua 120gr ammo. It shot pretty well. About 1-1.25 MOA groups out to 300 yards. I believe I'm going to be stuck loading lighter bullets with my twist rate. I'd like to use this rifle for deer out to 600 yards, and was hoping to load 130-140gr, but I don't think they will stabilize. Looking for some input. TIA
 

Partitions aren't sexy, but they work.
 
Actually heavier. 156gr IIRC.
Not in a 1-9 the Swede hat a 1-7.5 twist in the 96 Mauser the 121 gr hammer will work that's what I shoot in the 6.5-284 1-9 the 130 gr accubond will work also but I would prefer the 121 gr hammer 600 yds is a little beyond effective range in my opinion though 400 yds would be my limit with the velocity you will achieve that being said watch your impact velocity minimum recommended 1800 fps on the hammer
 
The question regarding weight was not about the heavy bullet in his rifle.
The 121 gr hammer the 130 gr accubond the 120 gr ballistic top 99 gr hammer and 125 gr Nosler partition will stabilize in a 1-9 twist 6.5x55 any thing heavier probably won't that's my experience with that twist rate in that caliber the 121 gr hammer will perform above it's weight with a velocity gain that might fit the ticket for his twist rate if not the 130 gr accubond would be my second choice
 
130 and less would survice for most 1/9, but 135 and a 140Spbt (I've used in a mod70 264wm w/1/9 twist stabilized). Speer might have a 140 available?

I have a Tikka 6.5x55 with a 1:8 twist that shoots 140 Gamekings very well. I think you would be ok with those.
But, that's not the bullet I would pick for 600 yards. Berger has a stability calculator you could use. It will give you a good idea as to how stable the bullet will be.

A note of caution on that 96 action. They aren't very strong, not even close to a 98 action. I have one in 6.5 x 55 with a 28" barrel. Load have to be kept down. Other than that I love the rifle.

another bs story with no FACTS.
THEY ARE BUILT INTO 30/06'S in europe and CERTIFIED safe. as in proof rounds.
they do use 58700 vs 60000 psi, with a 25% safety margin, that aint much.
