I have been partial to the 52 gr. hpbt Sierra. I have shot a LOT of groundhogs back in Illinois and as long as I did my job, the rifle delivered.
I used to load them with 33.7 gr, IMR 4064 or about the same amount of IMR4895. I now use 38 gr. H380. I also use BLC2 but do not have load data at my fingertips.
My rifle just seems to prefer that bullet.
I did load up some 50 gr. Sierra Blitz bullets at warp nine. I was shooting at foxes prone through wheat stubble. I could not figure out why my bullets were not reaching the target until I noticed puffs of snow about 60 yards out.
Either I was hitting wheat stubble or the bullets were blowing up. Not sure which. I still have the partial box of bullets and will probably never load them up. . .
