I'd hardly consider what I wrote a tirade and I do feel I answered your questions. Who decides what's "general all around use"? I'd be willing to bet at least 95% of the people shooting cast bullets never shoot past 200 yards and probably 99% never shoot past 100. For the vast majority of cast bullet riflemen out there an under an inch 170 gr bullet in a 16 twist would be the perfect fast general use combination. It's not that I can't relate what I've learned about slow twist barrels it's that you can't or won't understand it for some unknown reason. Your answer is always some obscure "if you really know what your doing" thing while ignoring the advise and knowledge gained and willingly shared by people that do know what they're doing and have actually done it. I'll repeat what I believe and have said at least 100 times about .30 caliber velocity and twist rate one more time. Starting with a 10 twist you're going to find your best accuracy at around 1850 fps. For every inch slower twist you can add about 100 fps or so. I've proven it to myself with an assortment of .30 caliber match barrels and study of the CBA match results backs up my personal findings.
I don't buy your "dog in the fight" argument. What would anyone possibly have to gain by lying about how someone shot or the velocity they got. The people I was referring to that had a chance to see what would happen were friends of yours at the time and when I offered to come down and witness your claims I offered to bring my chronograph and a camera so there'd be no hanky panky. I also offered to let you bring unbiased witnesses who had "no dog in this fight". This isn't a me against you thing. It's all about being truthful and realistic about what cast bullets can do. The old "your methodology is wrong" thing can only work for so long before someone is going to want more than words on a web page as proof. Why keep trying to convince someone that they're doing something wrong when in reality they're trying to do something that ain't gonna work. Bottom line for everyone is keep the 10 twist .30s around 1800 fps or so and listen to the guys that have actual experience and you'll live long and prosper. Try to get the velocities with accuracy claimed by some proven by none and you'll have nothing but frustration. I also wish people would stop calling what we're talking about " Larry's theory" because it's a fact and known about long before Larry talked about it here.
