Hi just starting loading for 6.5, have had great success with 120gr Norma/nosler BT factory
plan to reload 129gr sst. With N160.
have just measured my chamber on my T3 at 3.280. If I load 20 thou off lands which is what i would do for my 223 & 308, that is very little bullet in the neck. The Norma measure 2.90 and are loaded to the canulure.
sould I start off loading to the canulure depth on the sst and vary loads then play around with length?
Does the swede like to jump? If so how far? I see some lengths in the loading data as 2.935 (hogdon for the 129 hornady sp which is a different profile to sst) which would seat more bullet in the case would this be a good starting point even though the profile as said is different? On SD some have loaded sst to 3.082 should I start there?
any help as always is very welcome
