Am interested in loads and OAL stats others have found optimal for this round in .243 caliber with H4350. May consider other powders, but right now have that in hand; and for same reason would prefer to use Lapua brass and BR2 primers -- but main point is to get some references on what is working for others, whatever the configuration of the rounds. Rifle is a Surgeon 591 with 26 inch Bartlein barrel. Thanks in advance.
Load for Berger 105 hybrid in .243
- Thread starter Roslyn
- Start date
42.0-42.5 gr of h4350 with win or lapua, br2, and a 105-107 bullet has shot great in several different243 1-8 twists i own. Also 43.0-44.0 gr h4831sc with mentioned components shoot outstanding. The h4831sc is usually in the 3000-3025 fps range in 24-28" rifles, the h4350 will get 3075-3150 in 24-28" barrels. My h4350 loads are accurate, but the h 4831sc show tighter es &sd, usually low teens es and 4-8 sd. Been starting to get low on h4350 so started to change my 243 loads all to h4831sc to save my h4350 for 260 and creedmoor rifles .
For the 105 Berger Hybrid bullets a .010 jump has been working well.
H-4350 is a barrel burner in a 6mm
For added barrel life on your 26 inch barrel give some H-1000 a try.
Start at 43g and work up to 46g
