Theres no load data for Hammer bullets. Once you replace a major component like the bullet your on your own. I do suspect there is something to Hammers PDR drive band technology, I dont have much experience but these Hammers shoot different than all others ive handloaded... they all shoot the same accurate group regardless of seating or charge, as advertised. I think this is why many hunters are raving about them right now.Bottom line, at 34.0 gr., you're up to the max. recommended load using a substituted bullet and a ball powder.
Im also not just only going by primer condition. Im including velocity and even fireforming size. At 34g my velocity was way low for any 30-30 and the brass shoulder barely fireformed. If I was even close to max at 34g I woulda blown up my rifle now at 37g.
yeah, I ignored the guy claiming 2800fps.
I did some loading this week and in my unscientific way checked for compression and do not think I am compressing the load at 37g but am close to full capacity. Im going to zero at 37g/2400fps... Im not going to chase another 100fps if it means compressing the load but did load 4rds at 37.1g to check velocity and pressure signs. Im hoping to get out shooting today so I gotta get offa here.
