[QUOTE="speedengineer, post: 1975924, member: 112986"] Interesting idea! Though, I think the difference in mass in front of the bullet will be quite negligible. Considering a 0.204" diameter bore, 24" long in front of the bullet: [ATTACH type="full"]213015[/ATTACH] That shows that by replacing air with helium, the mass of gas in front of the bullet will be reduced by 0.208 grains. This is less than 1% of your specified bullet mass. For a larger cartridge with a heavier bullet, the percent reduction would be even less significant. Good luck! [/QUOTE]
