rifle is my custom modern browning 1885 Hiwall rifle. [yes I know it is NOT an original Hiwall in any respect]. I had it re-barreled with a GM barrel in oct number 4 taper which is very heavy. it has a 14 inch twist and at .0025 inch deep rifling they are fairly shallow. barrel is 30 inch finished length. forearm hanger is in the same position as it was originally due to a milling a spot in the heavy barrel underside to allow for it and the ejector. the forearm is dug out to be in relief of the barrel. the chamber is cut as a 2.095 inch chamber and throated for cast boolits ...so I thought. the groove is .375 so it is not an original 38 cal.
I have shot this rifle with hornaday 220 grain to break it in and it did wonderfully doing so. thoroughly cleaned and ensure to have no copper wash of any sort I then set about to find a paper patch load that would do well in it. NO JOY.
I have wrapped 4 different thickness papers and wrapped boolits from .372 down to .358 with all kinds of paper to try all combo's for a boolit/paper combo that would work. boolit weights have been 250 thru 330 grain with lube to include my home made bee wax combo to now using SPG lube for all. I usually do not shoot lube on the patch's however I have just to see if it made any difference. have blown my brains out thru my blow tube and wiped the bore at other times to repeat the barrel to the same condition with each shot. I have loaded GOEX cartridge powder from 40 thru 55 grains with primers consisting of cci // Winchester // federal // Remington and both mag and large rifle heat. cases were Winchester and starline cases and in 2.125 down to 2.085 in length. smokless powder in RL-7 and IMR 3031 as well as 5744.
needless to say that over time I have re-visited this little heavyweight rifle to try to persuade it to come around for me with the paper patch and be able to keep it on a 6 inch target at 75 yards. so the question I have for ye'all is thusely;
do you all think that the shallow 14 inch twist is defeating me with paperpatch?
now for the pee cutter ... I can load 30 grain of RL-7 behind the hornaday 220 flat point in WW cases at 2.086 inch length with cci 200 primers ... these do absolutely incredible in the 100 yard accuracy dept. I can repeat groups in the sub 1 inch any time I take the time with my shooting. with a hot barrel or a cold barrel these bullets perform very well and repeatable anytime I desire them. I just don't want to shoot jaxeted bullets thru it. I spent a ton of dollars to have it built and now I fear I have chosen the wrong twist barrel.
what say yee. should I continue my quest ...or... determine if I should do a bit longer twist in another barrel? maybe get it lined to a better combination?
