RE: Buffers for rifles
Sorry for the confusion.Boy don't I feel stupid.
I was thinking of fillers not buffers when posting this comment but couldn't
remember at the time what was added to rifle cartridges to take up space in reduced loadings so I guessed.
It was a late night for me couldn't get any sleep so I went on the forum
at 3:30am to get some things off my mind.
Anyways, with the bullets I mentioned the 180gr TBBC, Hornady Interbond, Nosler Accubond one would think powder charge would have to be compromised because these bullets are long.Yes I'm sure you can
compress the loads but if one was to compare powder capacities between bullets ( eg. partitins, interlock,hotcor) and the bonded bullets you probably will find that the max charge of powder will be reduced in cartridges that use the bonded bullets.
For my moose hunt this year I handloaded 20 3006 rifle cartridges using
TBBC bullets and 52gr of IMR 4350 that was the starting load.The max load of powder that Speer loading data offers for this 180gr bullet is 54gr MV with the 52gr. is only 2568fps. MV with 54gr is 2606fps.
H4831 has a min charge of 57gr( MV 2606fps) and a max charge of 59gr
MV 2689fps.
Keeping this in mind how then are comercial cartridge manufactures able
to break the 2900 fps with a 180gr bullet in a 3006 cal. if some other loading method has not been develped and now used.
