The 55, 55.5 and 56 grain loads all had similar accuracy and point of impact so I would choose this range. I would choose 55.5 to give you a good margin of error on charge weight accuracy, and provide some wiggle room for high/low temperature variation. IMR4350 will be less temperature sensitive than 760.

Thanks SG, I'm using a lee powder dipper along with a digital scale and trickle to the tenth.
I don't mind the extra time.

what temp range do you hunt in? If the temps could be near or below zero I would go up to 56 to make sure you don't fall out of the accuracy window on a cold morning since you are trickling. I test my deer loads at -20 to be sure I know whats going to happen. Cold can do crazy things to POI!

Our temps in MS. can get down to 18 * so I'm hoping things will work out for my powder, primer and the groups.

Which a lot folks say I'm good to go.
I do plan to shoot again closer to the hunting temps.

I agree, this is the direction I would go given these groups too. If you pick the 55.5 gr you might be able to play with seating depth to refine the load.

Thanks Gtscotty, out of curiosity why not the 56 load ?
It holds tight and probably has upper 2700 velocities .

Thanks , LTH

I would probably load up 55.5 and 56 with different seating depths to fine tune, and see where I find the best accuracy. I might lean towards 55.5 because it's right between 55 and 56, both of which are fairly similarly placed on the target, whereas 56.5 looks like it is starting to move up and left towards 57. Some folks say they don't see any changes with seating depth, but I shoot almost entirely hunting type bullets, and at least with those type bullets I've found you can almost always fine tune with seating depth for best accuracy.

I used to use 56.6 gr of IMR 4350 under 165 SST's in a Tikka T3 I had; that load chrono'd at 2840 fps out of the Tikka's 22in barrel. I'd guess 55.5 and 56 are going to be pretty close in velocity around the high 2700's or maybe 2800 out of your 24in barrel.

Thank you GTS, I'll experiment with that .
