Morning guy's, I recently bought a 114 American classic in 270. I am getting everything together to start reloading get for it. I want to push a 140 grain bullet really fast and flat. It's going to be my moose/deer rifle. What powders should I lean toward? It's not my first go at reloading and I have a few books. I plan on being near the top end of the load data if it's accurate. I'm just not sure which powders will do what I need. Thanks
Jesse.
Imr 4831 is what I use.
Jesse, 52 grains of I 4831 pushes my 140 grain Sierra Game Kings out the muzzle at 2800 fps, so you may want to take a look at that powder as a possibility.
Not sure on the speeds (Chronograph is my next item to buy) but I use H4831 and it had two nice group nods one high one low in the powder range. I use Hornaday 140gr SSTs for what its worth.
Look into the berger classic hunter 130gr option. Very high BC in fact higher than their 140gr vld offering. Higher BC translates into more retained energy down range and the lighter weight means more velocity. I am getting 3030fps out of my factory savage 22" barrel and 54gr of H4350.
What is everyone's opinion on bullet weight? 200 yards or less for moose? And I know shot placement is key. Shoot em in the boiler room.
150g and rl22
Is a 1:10 twist enough for 150 gainers?
mine does I have a numrich 270 mag profile and it does
10 twist is plenty for the 150 grain bullets. If Moose is on the menu I would not consider anything lighter than 150 grain and would give the 160 grain (10 twist should be ok ) Partition a very hard look. I know Jack O'Conner used a 130 grain Partition on moose but I would prefer more bullet weight. H4831 usually gives good accuracy with max loads for me, just work up slowly.
