Anyone shooting the 143's in a 260 Rem or a Creed ? I have 4831SC and RL 19 on hand. How much of a jump seems to be working? Rifle is a Tikka T3 with the factory 22.5inch long 8 twist barrel.
thanks, Jim

Have exact same rifle. 44.0 - 45.0 gr H-4831sc and 50.0 gr H-1000 were good loads - both easily sub-MOA. Seated to max. magazine OAL of 2.800"

Thanks for the quick response.
I have a spare mag from a 30-06 T3 and was willing to modify the bolt stop to allow longer OAL if it improved accuracy. Have you chrono these loads?
Thanks Jim

Have not run them over the Oehler. Should be right at 2,700 fps.

I normally run 44 grains of IMR 4350, with 140 grain bullets, and the load proved just as accurate with the 143 grainers.
MV is 2750 fps out of a Ruger 77, 22 inch barrel...
with 4831 SC, I'd go with 47.5 to 48 grains with it... MV should be the same range... 2750 fps...
RL 19 same charge...MV should be a little faster than 2750 fps...
H380 or H 414 ( W 760 or AA 2700, same powder) will yield faster velocity
all had great accuracy in my Ruger, 1 in 8 twist.

A max load of Re 19 should be good. I loaded the 147 ELD-M over a max load of 19 and got 2725. The 143 should be a bit faster.
