Slugsrus.com is recommending a new powder for loading their 12 gauge SPW with hammerhead slug. It is called ProReach Long Range powder for 12 gauge by Alliant. A big thank you to long time customer, Mr. Larson for sharing the load information in using this powder. The 'Larson Load' has proven to be more comfortable on the shoulder when shooting and is very accurate. Check out our updated 12 gauge load data and 20 gauge load data.
