16" twist in 32/40 (Read 4062 times)

	What are the general bullet weight range in 32/40 for a 16" twist rate? Newly acquired rifle has 16" twist, my other 32/40's all have 14". Would imagine the bullets that work in the 14" twist I use 200-210gr probably won't work. It is way to cold currently here where I live to go to the range. bob

	My original Ballard barrels in .32-40 are all 16" twist and work good with a 190 gr. bullet. Never tried heavier, but can't imagine a 200 gr. wouldn't work well.

	Accurate mold bullet. 187gr and 200 yard group. Base is exactly groove diameter. Minor diameter is exactly bore diameter. 14.1 gr 4227. WLR primers. Old 32-40 Remington barrel with six grooves, 16 twist. 20-1 alloy. Bullet breech seated ahead of the Hudson throat.

	my original Winchester barrel likes the Ideal 319289 in 20:1 and around 186 grains shoots best with 14.1 grs of 4227. I also have a bullet from Jerry Simmons estate that weighs about 193 grains but has a stubby blunt nose. Good with 4759 and 4227.

	For a 16 twist it would be three times the groove diameter for the bullets length. Weight is actually not the determining factor.

You know me, low tech. Another rifle with a 16 twist shoots the Ron Long spitzer at 1.170 long most accurate. So that's why I never rely on numbers. The Accurate bullet in my previous post is .957 long. Results on the target.

	I have a High Wall with a 16 twist liner installed and it will only work with bullets under 190 gr. But I have an 8 groove 16 twist barrel on another HW that shoots great with both of my 208 gr bullets. Neither work well with the Seaco 200 gr tapered bullet that shoots well in my 14 twist HW and my 11.5 gain twist 32-40 Ballard. I only have 4 32-40s so far. Jack

	If being a Spitzer Bullet the Bullet length can be abit longer based on my own 16 twist 32-40 experience. But why even try to push it to that extent ?

	Thanks to all for the info you shared. One thing you all confirmed, my rifle will let me know what it likes best. Will try the molds I already have before I go order a new one. You all have a good day. Bob Iowa

	Early in my shooting career an original high wall in 32-40 and an old 200 grain Ideal 31952 mould crossed paths at my place. I was stronger and had better eyes back then and with a good set of tang sight could regularly break skeet birds laid on the berm at 135 yds. That was fixed ammo with 13.2-13.6 gr of IMR 4759.
