It would appear that is not enough to make the velocity difference according to QL . Both should be close to 1800 fps with a 20" barrel.
As the others have said you need to run a string with each to tell the actual velocity.
Also the less friction on a bullet or in the barrel equals less pressure which equals less velocity. (exception would be long barrel and low powder volume where barrel length begins to slow down bullet. In that case less friction can equal more velocity. Example 22LR with long 24" barrel, some friction proofing products have seen increase in velocity)
I run HBN on all my jacketed rifle bullets and when I switched from non coated to HBN coated I lost velocity with 2 different 30-06 rifles, 2 different 6.5 CM rifles, a 308 win and a 243 win. The lower friction allows adding a bit more powder and in the end gaining velocity. (with the 6.5 CM using RL26 it was .5 grains to equal velocity loss)
