220 swift reloading

[Beardog]

Hello

 

Ok well I took the swift out today with my new loads. I feel the results were inconclusive, only my second reloading project. Using a Rem 700 varmint 24in fluted barrel, not sure of twist. Used once fired Norma brass trimmed to 2.195 and COAL of 2.680. Used varget powder and 40g Vmax. I loaded up five rounds of the following with following results. I'd already ready established its max pressure.

38g 1.035 more vertical spread
38.4g 1.009 --- .541 round group
38.8g 1.094 --- .665 round group
39.2g 0.984 --- .632 round group
39.6g 1.306 round group
40g 0.645 round group
40.4g .930 round group
40.8g 1.024 more vertical spread


Its an old barrel so I’m taking that into account, but I had hoped for better groups. All groups, grouped well, reasonably circular groups, pretty much clones of each other, just varying in size.


With the 2nd, 3rd and 4th groups. I had four very tight holes and a 5th hole about half inch left and half inch down, all three identical. Not sure why. If I take away that 5th bullet the groups were as above.


So my question really is, what next? I’m thinking I will redo 40g and 40.4g and also 38.4 and 38.8g

Cheers

Alright,

Found with my swift, Rem vssf 26'' barrel preferred H414 with the 40gn Sbk's. Use Varget with the 50gn Vmax. Also try pushing out the C.O.L a bit. I know you won't touch the lands with light bullets in a factory chamber but you might get better groups going 20-100tho out or so, or a bit in.

Regards,

Ben
