Handi-rifle throat length
« on: February 14, 2005, 10:39:55 AM »
Anyone know why the long throat on some calibers, and such a short throat on others?  My .30-06 is very long, and my .45-70 is so short I can't shoot 500 grn round nose bullets.  I've been thinking about calling H&R and asking, but thought some one might know.

As best we can tell, it is mostly the high pressure rounds that have the long throats.  It is a known fact that if the bullet has a slight jump before hitting the rifling it reduces the pressure spike in the chamber.

In most of these and many other brands that do the same thing it doesn't seem to have an adverse affect on accuracy.

You could also lengthen the throat a little if you like, or have a gunsmith do it for you for very little $$$.

I've thought about throating, but hate to risk an accurate rifle.  I'm deferring a decision for a while.  I was curious about how many calibers had long throats.

New reamers are made to the maximum allowable SAAMI dimensions so that they may make the minimum dimensions after being shapened so many times. It's the luck of the draw where your firearm may have been produced in this scheme of things. When the 45-70 surged to popularity in modern times, the book was rewritten for modern times on it. When Ruger built the first 45-70's in the #1 and #3 they had non standard chambers to cater to the BP shooters and long 500gr cast bullets. Marlin's reintroduction of the 1895 brought another light on the subject and the action capacity made the 2.55" length mandatory and the rest became history. :D
