slumlord,

If you can't find a cataloged lens, you might check with your local non-national chain opticians. If they can have the lab they work with grind eyeglasses to meet your prescription, they could probably duplicate your scope lens.

  

There are three kinds of men: The ones that learn by reading, the few who learn by observation, and the rest who have to pee on the electric fence and find out for themselves.

Good idea. Need to take a look at it again since I put it back together. As Redsetter said it may not be as bad as I thought. Still need to know how the pieces go back together. Thought I kept them straight but now I am not sure. Would be helpful if someone here knew what order all the pieces go in.

As a help to working on these type scopes, I'm opening a thread in Gunsmithing.

Hi Guys,

    Solved my delema with to tap and drill or not to. Went to CPA in PA yesterday and ordered a new barrel for my 44 1/2 Stevens. Can't ask for two nicer people than Paul and Gail. They took the time to answer my questions and offered advice that only comes with years of exper & knowledge. I now have a Douglas 28" #3 barrel half octagon and half round with a 1 in 15" twist on the way. The barrel will be D&T for both Unertl type scope blocks and an extra hole so that a Weaver base could also be used. 
    I want to thank all of you who replied to my post as it did offer much insight and helped me in making my decision. In this case the 44 1/2 remains untampered with and I will have a barrel that will allow me the uses of a scope, as well as a better than average chance that it will be an accurate barrel. I could have D&T the org barrel and found it was not as accurate as I'd be content with. So at the very worst in this case I will have an org untampered Stevens 44 1/2 and it is a two barreled set with a new barrel set up for scoped use. 

     Now I pose the question of what bullet to start with for distances of 200 yards and beyond. At present I have a SAECO #632 170 grain mold that is working for me in a 1 in 16" twist org barrel on a Stevens 44. Should I seek purchase of a mold that cast a bullet of 200 grains or more? I'd want it to be a tapered bullet for breech seating. What about a pointed or spritzer shape? Would like to hear your suggestions.

      Thanks, Sendaro

Good starting point is the Hoch mold CPA sells.  200 gr tapered. it's the result of a lot of experience rifle builder mold maker and shooters.

2nd mold want to experiment the Hoch will have given you a good baseline

Boats,

      Thanks for the reply. I've sent an email to CPA and asked them to suggest a bullet mold. I'll bet they suggest the same one that you make mention of. Have not had the chance to cast with a HOCH mold as of yet. Will I have to purchase HOCH mold handles, or will other mold handles accomadate the use of HOCH mold blocks?

You will need the Hoch handles for the Hoch blocks, the others will not work.

JLouis,

   Once again you are there to help. Thank you. What Hoch bullet? The spitzer or the traditional Schuetzen type? I plan to shoot at 200 yards and beyond. The beyond part is just to see what it will do. I have 500 yards on the range at our shooting house. It should be a hoot!!!!

Sendaro the Schuetzen as provided by CPA. I personnely feel there are better choices but that bullet is a good place to start.

CPA's Hoch is a fairly conventional bullet, round nose tapered and 200 grs. Main point is it's going to fit the barrel which is 3/4 of the job. It's considered to be a standard, nothing radical. Like J Louis says there may be better but it's a good starting point.

Started with it and for a dozen years never saw the reason to look for another. Am moving my offhand shooting from breech to fixed next season, ordered a duplicate of the tapered bullet that's cylindrical for fixed ammo, basic design, length & weight is the same.  Fixed is an experiment not recommending it for maximum rifle performance.

Some like the spritzers and I have had very good success with a 38/55 290 gr Spritzer intended to give better 500 yard results. However spritzers are fussy and mine may have worked more due to luck than design.  It's real easy for the long nose to slump on ignition, while the better B/C is marginal at plain base cast velocity. If it won't shoot due to too long, B/C is not important.

Others may see it different

Boats I tend to agree with you on the spitzers, it was my bullet choice for 12 years and I accumulated a lot of honors with it as well as some range records and a NT. This past year I started shooting a flat nose bullet and I can only say I wish I had done so 13 years ago. I like everyone else was caught up in the BC race, plus they looked cool and the longer and sharper the nose the better they looked. Nose slump is indeed the route to lost shots and once the nose slumps over and it is quite common there goes the balance and there wonders off the shot.

is " bullet (nose) slump" more of a problem with bp that with smokeless.   my understanding is that the two have a different burning rate; with BP having more of an initial explosion that gives the bullet a real hard kick in the butt to start, while smokeless has a more gradual launch.

I first heard about bullet slump when reading about the long range spitzers with their long unsupported and  bore-rider noses in the bpcr/quigly-shoot context.

DW not sure about the differance between BP and SL.
SL catch box results showed anywhere from .005 to .012 nose slumps.

OK Guys, What's up with nose slump. Just what are you making referance to? The bullet in flight tipping down as velocity starts to drop off in flight, or as it enters the bore at the start of being fired?

Sendaro I will have to explain my thoughts on it Via an e-mail, it's quite lengthy and I will get it off to you as soon as time allows.
