I bought my last 2 pounder a month or so ago from a gun shop we pass on our way to matches (about 50 mi. away). Don't know if it was not a good seller or what? Actually, I bought two. The first one about 4 months ago. When he still had the other one left this last trip, I bought it also  The short range benchresters were the first to make use of N-130. Then when V V came out with N-133, they liked it much better and N-130 fell by the wayside. Richard |

I have a TC encore prohunter with a 45-70 20" barrel. I use a push in breech plug to make it a ML'er. You may have seen it on the mod. muzzleloader forum. I get about 2550 from the short barrel with the 200 SST & 60 gr. H4198. I might be interested in trying a duplex like the one you used. So far..the sabot problem has not happened..I swab between shots too. I figure to try to have things as close to exactly the same from shot to shot.

Squirrelhawker........I do the same, but it seems others do the opposite and get good results so....................  It may be the reason I have not been blowing sabots and they have? The cool rod between shots and the smooth surface in the bore. Rougher bore...More friction.....Softer sabot. Just a guess? Also, when I get home from the range and do my cleaning procedure on the rifle, I end by short stroking a JB patch in the bore and then a final swabbing and dry patching. Richard |

Richard, Thank you for the info on your home cleaning process I do use the dry process both sides But I am a firm believer in the Jb clean up It is great for break in. Again thank you for the educational input.

Richard, Just a question why doe the bench rest shooter preferred 133 I can't find 130 but have 5 lb of 133 I have great exactions when I bought my Pack nor I was not smart enough to look at the options. Otherwise I would have gone as long as possible and if I knew it was available I would have gone with the top of the line lap It seems to work well for you. this something no one mentions when they can't under stand why one is better than another.

Jon......As far as the N-133? Its burning rate is better suited to the 63-68gr. bullets shot by most benchresters. Just like I have found N-130's burning rate suits my needs better than N-133! Not that N-133 will not shoot accurately in my rifle, just that because of the shorter barrel, I require a faster powder (N-130) to get the velocity I want. The benchresters found the accuracy better also with N-133.
As far as the better lap job? Personally I think its BS! I borescoped your barrel, Herman's, jhm's and mine. I could not tell you which one had the "super" lap and which had the "standard" lap? Maybe the tech at Pac-Nor ran the lap in a few more times, maybe not? I think my gun shoots the way it does, is because I shoot it a lot, I have a great high power scope, my rest has been tweaked the concrete benches I shoot from are solid and have gathered a ton of information which I use to modify and tweak my loads? No magic, just good equipment along with time and effort Jon. I feel bad you cannot get out more to shoot and try various loads. If my barrel was as long as yours, I would be shooting the N-133 more than I do. I had excellent accuracy with 133 and could achieve 2800 fps.
