Re: Need 220 Swift Loads: V-max 55 gr/Berger 55 gr Varmint - Varget/H380
Can't help with either powder or bullet choices you have, but in my Swift I shoot the 55 Bal-Tip with VV N-160 just an awesome powder in my rifle getting 3900 out of a 27" in 1-12. and it shoot's in the .2's....longest kill was 627yrds doe antelope.
I have also used IMR-4831 with very good results. Keep an eye on case length...the swift cases grow very fast. It is a great cartridge in any make rifle, just need to find the bullet/powder combo it likes. It is a very accurate cartridge.
I have found H-380 to be too temp sensitive for my liking. You should be able to get a load with Varget to work. You can call/email Berger and ask them, they will give you loads for their bullets.
