What kind of accuracy can you expect from a Danish RB?
« on: July 04, 2004, 06:47:14 AM »
I have a Danish Rolling block that has been reamed out to accept 45/70. I had a good time at the range yesterday loading BP and 4795 one at a time with my lee loader. This gun is a for certain man killer. I could easily keep all my shots in a 8in. bull at over 50 yards some kissing the same hole. But this is not a target barrel and the sights are like lining up your thumbs (rear sight wobbles left to right) I can see promise in both loads. what kind of accuracy can one expect from an average millatary piece? There must be some average that people want to leave behind to rebarrel and add peep sights? Thanks in advance for you info. JB

Accuracy is a product of way too may factors for me to even hazard a guess as to what the original Danish RB were design to produce. Probably "minute of a man" @  a certain range....

I would try to develop a powder & bullet combination that duplicates the original military rd., then tinker w/ the load from that point.

Having said that, one of the 1st things that I would do would be to slug the bore, measure the slug dia, then measure the bullet dia. to see how well the bullet fits the bore. then carfully look @ the crown for any damage or wear.

It would also be a good idea to measure the rifling rate of twist.

Of course if the sights & the trigger pull (which you didn't mention) are atrocious, all of this may be for naught....

You mentioned “4795” powder. Did you mean SR 4759 instead? In the past, I utilized SR 4759 & found that for it to work well, it should be held against the primer flash hole for complete combustion & better performance. In my .45-2.4" (AKA .45-70) loads, I believe I utilized a one-quarter sheet of toilet tissue as a wad, & gently tamped down over the powder charge. I have also observed Fellow Shooters elevating their rifles to slide the power on the flash hole area, then slowly lowering the rifles. I think the wad works better & is safer for the rang roof/overhead covering….

Unless damaged, most barrels will shoot better than a person can hold so it sounds like your sights are the main problem to fix.

Yes, the powder is 4759, I have a problem with that number.  It has taken me forever to buy it because each time I found 40 someting powder for sale I passed because I could not remember which one.  Old age stinks.  Thanks for the filler reminder.  I have kapok I can use.  I use kapok in many of my light cast 30 cal millsurp loads.  Since the Dane does not seem to be a high value colletable on it's own I think I will look into drilling it and installing a peep sight and matching front sight.  It is somewhat annoying to look at this front sight now as it is regulated way to the side for accurate point of aim to the rear blade.  Shoots straight, looks funky!  Thanks for your input.  JB
