When testing loads with different bullets??

[capitol]

Im going to the range and have loaded 70 rounds. All have W748 powder, but Im using vmax and speer bullets.

Should the barrel be cleaned before I shoot the different bullet? What if I was using a different powder?

Thanks for the help.

From my understanding you only need to clean the barrel if switching from solid copper rounds to lead bullets. Someone else with more expertise will chime in shorty.

It shouldn't matter. If you clean the barrel, you're going to have to foul it again anyway.

When load testing for my 6.5 Grendel, I was shooting 123gr amax's and 100gr ttsx's in between loads back and forth. No cleaning of anything. Did not notice a difference in accuracy. Accuracy was still moa to sub-moa out to 300 meters. Just my experience...others will have differ opinions.
