Has anybody here had any success with the 120g SIERRA HPBT MATCH KING and
AA2520 POWDER .
Or any other powder and did you load it to maximum magazine length of 2.260ish or what ALEXANDER ARMS web site has it at COAL 2.220 !!! with the 120g Sierra .
Why would this head have such a small COAL than say the usual 2.260 OAL that most of us use for the 6.5mm Grendel to have less pressure in the case with heads in the
120g and up .
The 120g Sierra HPBT is a normal shaped head and not a short stumpy head like a short hollowpoint so why the short over all cartridge length on the ALEXANDER ARMS web site .
I would have thought they would have had all their loads that they recomend all be in the 2.260 realm for OAL to keep presure signs down .
Or am I missing some thing here ???????.
I have been using LAPUA 123g heads for years , but the cost of them have went through the roof over here in the UK at £320 or $500 per 1,000 , so they are out .
The 120g Sierra`s are alot more afordable , so that is why I am looking at them .
Any help would be appreciated .
