[QUOTE="justincase, post: 2942403, member: 80421"] For what its worth; I have had good personal experience with Hart barrels and of the very few complaints that ive heard about hart, none have been validated.. If barrel length will be over 26” yes varget will be a prime candidate for powder choice. Dont remember who said it but there is some truth to being able to push a heavier bullet faster in a select few situations. High capacity cases, with small caliber bullets will sometimes show pressure signs at certain velocity, where a slightly larger diameter/weight bullet can be pushed a little faster at a lower pressure. Just simple physics - you can vent the pressure out of a bigger hole faster than you can a smaller hole. Fast barrell twist rates contribute to higher pressures too. Fact: a 30 cal, 125 grn bullet can be pushed over 4k without any sign of pressure with a 1:15 twist 30” barrel. This would never happen in a 1:10 or even a 1:12. [/QUOTE]
