OK, so here we go! Let me preface this little "ditty" with the following facts: The re-cut .45 Pac-Nor barrel is now exactly 23" from breech to muzzle. The tight/loose spot has been moved back to approximately 3.4" forward of the breech. I am using a recessed breech plug and 56 gr. of H-4198 keep the bullet/sabot form loosening in the bore. In other words, when I seat the bullet, I do not feel the sabot get loose! Temps today were 50 to 65* with light wind. All shots at 100 yards using Harvester blue smooth sabots. Bullets were all 200 gr. XTP's. I used my 4 drops of Rem. bore cleaner on a 2x2" patch, in and out, followed by two more dry patches. (in between shots) These get re-used for five shots. The "cool rod" is also used in between each shot for about 30 sec. The barrel NEVER gets hot, so it only takes a short time to keep it in a "normal" condition/temp. I also installed a new Weaver 4x16 CV A/O scope. In finding the height of the powder column at home I used two sabots which were in and out of the bore several times. So, being cheap ;D and not wanting to waste them, I used them at the range for my first two shots. I had Herman watch my first shot on the berm to confirm POI (which was about 6" low of POA) A scope adj. was made and I proceeded to fire the next (used sabot) shot into the start of group #1. As you can see, it was high and to the right. Note: This load was 56 gr. of H-4198 ALA Double D! Well, as you can see, shots 2,3 &4 formed a .324" cloverleaf! (This is causing Major Wood!!!) Made a scope adj. and fired a 5th. shot in another target. From here, you can follow my list and view the actual targets. The last group was shot with a duplex, don't know who gave it to me, but it produced the worst of five groups.......Ha! Five shots in 2.2" (my .50 on a good day). I have included pictures of the sabots...........As can be seen, the five from this duplex stressed the skirt on the base. Herman and our friend Bill also saw some flames come out of the muzzle. I also kicked pretty good. This load will be modified/replaced. One thing I noticed was I did not get a lot of good "ES's" with any of the loads. In that area, my .50 did better??? Still have a lot of "stuff" to try. However, even with the large ES's, accuracy was phenomenal. Thanks for putting up with all my shotgun patterns this past year or so. As you can see, I am able to shoot with a decent barrel. Richard (In group four I did not want to mess up my pretty little three shot one holer, so I shot #4 & 5 on the next target )

Hey Richard, Glad it finally came together for you.Very impressive groups. Herman has already PM,d me talking about getting him a 45. Larry Well since you have two might as well get one for yourself. ;D Good shooting Rich. Shame your barrel still has the bulge, but still cranked out some nice groups. Look forward to seeing more.

Dave W.............I really don't think that "little-bitty ole' bulge" is going to cause me any problem other than the shorter length. The bulge was not that severe, in my opinion? When running the sabot down the bore, yes, it would get "looser" but not like it was going to fall thru? It was still relatively tight. Yes, there would have been a concern shooting sabotless, since we are playing with ten thousands of an inch making contact. Next week I will play with some more loads and probably put a target at 200 yards I have some of the Barnes 195's and the SST's yet to try also.......Man, I got of lot of #$%#@ to try! ;D Anyway five shots in the 2700 fps range did not blow up the barrel, so I'm feeling pretty confident it will hold together. Richard

Richard
If my eyes aren't playing tricks it looks like you have an arm/lever on top of your scope. Is this a type of level that I also seen on Harleys scope. If so where can one purchase such an accessory?

Richard, congratulations!! I know you are relieved that your shortened barrel still shoots well. I would be tickled silly by the worst of those groups! YeeeeeeHaaaawww!

Who said Richard couldnt shoot? Richard I have been using a lubed wool wad and the sabots look hardly used other than petals missing. You are really going to like the new barrel ......Bill

Very Nice! I'm glad that you got everything worked out. Standing by for additional range reports.... maybe those SST's will tighten the groups up even more?

Thanks all! Yep, glad to be back. ET........Yes, thats the "Scopelevel" available at most all of the supply houses. They come in 1" and 30mm. Great with the rounded forends to keep you on the level. Richard

Dave d.........how do the velocities I got compare with what you get on your rifles? Also what length are your barrels? Both the 56 gr. H-4198 load and the duplex. Richard

Just kidding Richard. Nice shooting and I'm glad you're getting the kind of results you've been trying for.

:)richard,my barrel is 24"s with a 1.250 plug and i get 2500fps with 56grs of 4198.60grs will give me 2600fps.i just looked thru my notes and i don't have the velocitys of those duplex's.so it looks like you are around 75fps down which is no big deal.keep shootin i want to see more groups ;D.

Yes, Ed, I recently put a ScopLevel on my own rifle. It took a little effort to be certain the action, scope and ScopLevel all agreed. I was surprised to find that I normally cant the rifle; the Scopelevel helped me correct that tendency. I ordered mine from: www.eabco.com/Gadget01.htmHarley

Glad you getting what you like,Richard! 'them little groups! By the way-those used sabots look still OK-maybe you try and shoot with them again. (you can call it "recession" sabots ) I won't be surprised if they work.

Its funny how you don't realize you are canting your rifle until you get one of these gadgets. All my bench guns have flat forends and I have a level attached to the rest. At the matches, most benches are pretty level to start with. So, after getting my stuff set up on the bench, I just level the rest and never worry about canting the rifle. Now with these rounded forends and particularly the thumb hole stocks, its easy to feel you are set up perpendicular when you are actually not. I really got Herman doing some serious thinking ;D Its just that since I took him and our friend Bill up to the 1,000 yd. match on Saturday, that is all that is on his mind. I also sold him a 6.5x284 rifle and he is spending $$$ on custom dies and I have to put a muzzle brake on it $$$. I might also mention that our club has an all out custom light class benchrest rifle that "newbies" can draw straws to shoot. Ammo and all. I was able to get Herman to shoot it (since no one else came forward to apply) and he won his relay and got his first "relay pin" for score. (46 out of 50) Congratulations Herman. Here again, he saw the difference between shooting a Factory rifle and a Custom one. (It was also a 6.5 x 284) Richard

Richard and Harley
Thank you both for identifying the tool and where one could be acquired. On my last outing my hunting partner caught the slight cant I had on the 10ML-II and that is why my posted group started to arch to the right. Hopefully I don't get a hassle for ordering 2 and hopefully they will ship to Canada.
I need those training wheels to break a bad habit. ;D

Dave d.........how do the velocities I got compare with what you get on your rifles? Also what length are your barrels? Both the 56 gr. H-4198 load and the duplex. Richard With 57 grains of H4198 I clock 2618fps +/- 35fps. My barrel is 25" but my breech plug is only 1.5" so my usable length is 23.5"

Rich, I shoot 10gr N110/49.5gr H322 @ 2690, have to use a veggie wad or it will blow sabots intermittently like Dave D said. 12/48 N110/2015 times nearly identical but without the wad. Both loads are with a 195 BX. 56gr H4198 almost 2600 with the 200 XTP. 24 5/8" usable barrel.

OK Richard, now you will be tuned in with one-holers and get bored. At that point all you'll be doing is wearing it out. Then what? Seriously I'm glad it came together for you. Another bonus for us .50 cal dinosaurs is that the price of components will drop for us since you aren't using them anymore and are no longer creating excessive demand. ;D

This may be going off thread, so I apologize if I should have started a new one, but all the reported loads/MVs above reminded me that I have a question about the chronographing you guys do.
I have an Oehler 35P that I have had quite a few years. I normally set it up so that the middle screen is at 12' from the muzzle, but have also set it at 20' at times. I have not been doing the math to correct instrumental to actual MV. Mostly using the chrono to help me work up loads for my own use, and not to compare loads from other sources. Now, I'm thinking that I should be doing the correcting for any load numbers I might post here. How do you experts do it?
