Like'em.
Before getting into reloading, and then the introduction of Federal Premium ammo, used the ole Dual-core Grand Slams back in the day.
Then migrated to a combination of SPEER Hot-Cor and NOSLER Partitions for load development/range fodder/hunting as they tend to shot the same.
Now the Grand Slam is a "Cup-n-Core", using the SPEER Hot-Core process with a three-part Lead alloy in the same tapered/fluted jacket.
...and they are no longer Premium priced.
($0.22/pop w/ factory rebate)
So have gone back to them for both my .270 Win/150 gr. and new 6.5x55/140 gr. loads.
At muzzle velocities of ~ 2800 fps (in the .270, have not loaded the 6.5x55 yet), they are not over-stressed and seem to perform like the old two-core bullets - accurate with good expansion and penetration.
So, am I alone on this bullet, or do others here have experience w/it?
