Will this bullet stabilize in a 1 in 13 twist?

I want to use the 85g Nosler partition in my 20" 6BR as one of my deer rifles. Do any of you have actual experience loading the 85g NP in a one in thirteen or fourteen twist rifle? What about accuracy?

I also have a similar .244 Ackley imp with the same twist in a 23.5" bbl. Would the results be similar? I fired some 95g ballistic tips and 95g SST's in the Ackley this morning with both loads getting 5" groups at 100 with the bullets keyholeing. I would appreciate your thoughts.
 
Your barrel in a 13 twist should get a 80-85gr but it also depends on the brand and velocity you push them at the 244AI might stabalise them with the extra velocity where the BR might not the only real way to find out is to load a few and give them a go.

Cheers Bill
 
Sam, the 85g Partition will not stabalize in a 13 and is marginal at best in a 12. I have also had a lot of problems getting the 85g Partition to shoot accurate, the Barnes 85g tripple shock is a much better bullet, but it needs a 10 twist.

For your 13 twist, most bullets are varmint bullets and perhaps the three best bullets are the 80g Winchester, 85g Sierra BTHP, and the 85g Sierra Spt with the 80g Winchester probably being the better bullet for the 13 twist and the toughest also.

I loaded the 80g Winchester in a 243 for a good friend. He killed 19 deer out of a box of 20, and he killed a dog with the 20th shot of the box.

Good luck!
