Ernie, Only had 20” barrels. One for AR and one for Howa Mini Action. Best shooting powder was IMR 8208 in 123 ELD M. CFE shot ok but it had a tendency to build pressure rather quickly. If you use it especially in hot weather be careful of pressure spikes. H335 shot really well with 85-90 gr bullets. This was out of 20” rifle barrels though.
