I loaded 400 rounds of 45 acp 200 grain Berry's plated swc (using 4.6 bullseye powder). First couple hundred cycled perfectly.....accurate as hell and low recoil compared to 230 factory ammo so plate shoots have shown a great improvement in my times. Had 4 failed to feeds on my latest batch of 100. Had a buddy look at them that has been reloading for 20 years .... Looks like I didn't crimp them enough and they are hanging up on the feed ramp. I was giving them a light crimp because they are plated......but seems I was too light on the latest batches. I'll run them through the crimping die tonight and tighten them up a bit and I'm pretty confident it will fix the problem. Very satisfying so far in making my own for the 1911. It's a learning process
