Will go buy 30-06 dies soon. A friend offered to give me about 500 .309 match bullets. Many people state that the heavier bullets can create too much gas pressure for the op rod. Is this also the case if you reload with the minimum recommended powder, such as IMR 4895, very similar to original spec. GI powder? My only reloading so far is for the Enfield #4 and #5s, began last February.
