in2anity wrote:Nice SHV - love your work mate, all things considered that’s a bloody tidy group for irons They must be fairly hard to handle 21gr; holes look nice and concentric so looks to be stabilizing well. Just curious how low did you go? 17gr 2207 under a cast bullet is popular in the 30/30. Did you chrono them?

Your TB group has some room for improvement; 10gr TB is pretty hot for the 30/30, I’d start at 7gr min 9gr max, moving up in .5 or even .3 GR increments.
With regard to your 2207 load; 2207 isn’t the cleanest powder, then again it shouldn’t cause excessive smoke. Your theory about the velocity might be plausible. That 21.2gr would be a good small-medium game hunting load though; I’ve hunted with 20gr 2206 under cast; it expanded ok, reasonable accuracy. But yeah, for 2207 try starting at 16gr through to 20gr, possibly with magnum primers.
Keep up the good work!

will do and update later
thanks a lot and BTW what's single action data for? is it mainly for cast lead?

It’s for single-action cowboy shooting, where you can only shoot lead (close range, metal targets, reduced loads)
in2anity wrote:Really good shooting SHV You can also sort your projectiles based on weight; there is sometimes a surprising discrepancy in those commercial cast projectiles. Oh and another thing, you could start to experiment with lubricants; a simple pan lube of 1 part paraffin wax (candle wax),1 part pure lard and 1/2 part beeswax tightened my groups up a measurable ammount. Take a squiz at my thread viewtopic.php?f=2&t=6817&start=54#p106634

But that isn't great for lead bullets. They Tenn to strip at lower speeds\pressures
Even my Marlin 223 doesn't like hot loads and I think this is the reason. My 3006 is the same.

Yes, but SHV's is a Winchester?
With regard to the microgroove and lead; I know that's the commonly circulated theory, but I think it's more or less a myth. I've done a lot of load development for the 30/30 microgroove and I got my groups down to a consistent 2moa:
I'm yet to see a winnie consistently group much tighter than that. I just don't think the microgroove is much of a (negative) factor (with lead).

That looks about right; if you had some better sights it'd probably put 5 into an inch at 50m (i.e. ~2moa). SHV you should get it drilled an tapped for a rear aperture; that'll go a long way in realising the rifle's potential.

cool! was going to suggest the lyman looks right at-home on the 94! very nice! Btw who does your gun-smithing?
