Oh, and Speer lists this load as max velocity of all powders. The powder is compressed at that load with that boolit at an OAL of 1.58". Now I know why the 15.0 grain load is considered tops. My burning rate chart lists N110 right next to Lil Gun.Įdit: I just loaded some of the same boolits with 15.0 grains of VV N110. I likee the accuracy with a peep sight and a 1/16" brass bead. I have gotten safely to 14.5 grains N110 with no pressure signs.
One coat of Smoke's John Deere Green and unsized. In my alloy, COWW, it comes out at 160 grains. The boolit I am using is Lee's 158 grain flat point plain bae. My Speer reloading handbook Number 14 lists a maximum charge of N110 as 15.0 grains ahead of a 158 grain jacketed boolit in a rifle like mine. N110 is a cut powder and seems to be easier to light. They seem to need small rifle magnum powders. I have had trouble with the speherical powders like W296 and H-110 being hard to ignite. I have been working with VV N110 in my Marlin 1894C levergun in.357 Magnum. Considering it for hi-vel loads in a 32-20.Yes. At any rate, final dial in with the scope should be done with the rifle configured as you intend to shoot it.It gets great reviews for clean and consistent performance and available locally. Many silencer manufactures claim a minimal POI shift with their products, however I think it is more a function of altered barrel harmonics than silencer design, but I couldn’t say for sure. Point of impact shift with the silencer attached and detached was significant in my application. I know this seems nonsensical, but I have observed it on every load. Once you have determined that your load is on spec for velocity and is stable, then you can finish up fine tuning the load for use with the silencer, which in my experience will general add anywhere from 10 to 25 fps to the velocity of any given sub-sonic load. An unstable bullet could very well contact the baffles or end cap of a silencer resulting in damage. I tried many different bullet and powder combinations and more than a few failed to stabilize in my 1-8" twist barrel as was evident by the key-holes in the target.
Keep forgetting stuff! If you plan to shoot with a silencer, you should do your load development without it installed on the rifle. I didn’t like many of these powders due to the smoke they produced, which would linger for quite some time trapped in the baffles of the silencer, leaving a steady wisp of smoke coming out that would obscure my vision thru the scope on calm days. VihtaVuori N110 = 9.0 gr gave 1050 fps, great accuracy, no smoke. Hodgdon H4895 = 14.0 gr gave 1044 fps and decent accuracy. This was a load the 300 Whisper guys have been shooting for years. Hodgdon H110 = 9.6 gr gave 1041 fps and decent accuracy. IMR 4198 = tried 10.2 gr to 10.7 gr and the extreme spread was always high and the loads not very accurate My results differ a bit from the published data, but I think every rifle is unique in this regardĪlliant Unique = extreme velocity spread and pierced primers and sticky extraction at around 860 fps which was 6.0 gr of powderĪlliant RL #7 = 11.4 gr was a compressed load, velocity was low 981 fpsĪccurate 1680 = 11.2 gr was a good load 1024 fps and is reportedly the go-to load for autoloaders. That said, I tried the following powders with the intention of finding an accurate sub-sonic load with either the Sierra 220 gr hp bt, or the Hornady 225 gr hp bt The OP didn’t mention if he was trying to load sub-sonic or if he was using in conjunction with a suppressor/silencer.
