Jim,
The 55 NBT with IMR 4895 was one of the worst I’ve ever concocted.
WOW one of the BEST loads i have ever used in a half dozen 22-250's over the years for me ! RJ
Jim,

bump...
Brand new to the caliber I am. Picked up a south paw version because availability in my $$$ range was soon to be extinct. It's certainly not the rifle of my dreams but I couldn't wait any longer. I am making best on very recent life events that have changed perspective.
I've read the threads regarding combinations others have had success with but need some solid direction. I realize that the twist/bullet length is important to understand to obtain performance but I would like to confirm what I am picking up from what everyone is putting down.
Given: new Savage, 1/9 twist. Lego construction version if you know what I mean but I am gonna dial it in if it lets me.
Powders: 4166, w760, Staball, Varget, N540
Primers: WLRM, F 210, F GM215, CCI 250
Intent: primarily a coyote and beaver round that has 4 season capability. Consideration to include different bonded/premium C&C /partition bullet option for deer - thinking of my daughter in the future. Don't want to re sight based on game/season if it can be minimized or avoided or at the very least satisfied that it will work at some determined distance with the same weight of bullet.
I am thinking 55gr bullet .... but would like to know if I have that right?
Experienced suggestions for bullet weight / manufacturer and powder combo for above givens from those that have a similar setup is what I am after to get me started on the right foot. Or at least what you would put your money on to start with?
Thanks to those that have already shared in the post. Some good content for me to build off of and it's appreciated as a launch point.
Regards and have an awesome weekend!

Practically speaking, Dan is correct - the faster twist usually works fine to stabilize "heavier" bullets - but is technically the length of the bullet that is affected by / related to the twist rate - usually, but not always, a longer bullet is heavier, as well. Go back up to Post #14 to see pictures of lighter bullets that are longer than heavier bullets, of the same diameter.
If you are right on the edge - perhaps why flat base works fine, but not great with a Boat Tail of the same weight, the Boat Tail bullet will usually be longer. I have no experience with them - your 9" twist might do fine with 60-something grains, may not do so fine with 70-something grains.
A 9 twist will let you run heavier bullets normally. Try some in the 55 to 69 gr range. - dan

I have to correct myself...I posted the incorrect twist. I was looking it up on the Savage website and the first model specs were for the 223 and not 22-250 in the mobile view. I looked it up again from the PC and realized my mistake. Listed is 1:12 twist. Apologies for the error but I appreciate the response Potash and Dan.
I think that combination is cool! Franken it is!
I am going to ladder all the powders to see if anything jumps out as head and shoulders above the other with 55gr pills. Not to put this thread into the rhubarb but I tried W760 with 150gr bullet in my 7-08 and the ladder group was incredible Didn't do well at 140gr where my hunting bullet preference is, so I abandoned it for that reason. 760 was significantly better compared to other choices so I know there may be a preference that sends it better than the rest. H380 is where I will start.
Thanks all.
