Levels of competition shooters understand that the bullet’s position during the chamber throat/leade can noticeably affect accuracy. Sometimes, I've experimented with different bulletseating depth to achieve better groups in my bolt steps, though the genuinely short throat of your 223 Rem. cartridge case seriously limits exactly how much you could vary bulletseating depth, so I haven’t completed Significantly of it.
"Given suitable penetration, a larger diameter bullet can have an edge in wounding usefulness. It'll destruction a blood vessel the lesser projectile barely misses.
Insert to quotation Only show this consumer #13 · Dec 23, 2012 No doubt Fred, as normally I enjoy your input. I've it narrowed down to a nosler fifty two gr custom made competition hpbt or a fifty gr zmax bt. I will likely be using them within an ar-fifteen rifle primarily. I'm not selected a powder and will likely not know until finally I commence establishing test loads as mentioned in many posts. I just picked up some H335 to try out and I think I have Various other spherical base powders which i will seek to operate from the dillon powder evaluate too for examination loads.
The post relates the near destruction (bolt lugs established back and also other harm) of a personalized gun from slight excursions past reloading handbook maximums in the course of a ladder screening technique. This was working with H335 as well as the creator was chasing velocity during load growth.
As we predicted, The 2 spherical powders had been quite close. Even with a 400x microscope, very small measurements were being challenging to discern. We couldn’t explain to a distinction from the duration of Varget vs H-4198, although it can be visually apparent Varget has a larger diameter.
Incorporate to quote Only show this person #4 · Sep eight, 2016 Here is a connection to your DuPont archive file that exhibits IMR powders and involves Remington bullets. It can be old data. Notice that the photographs of the powder are in the previous square cans.
I have already here been reloading for near 40 years and you've got misplaced me Along with the discuss of head House and so forth. I load and shoot, searching for signs of about strain and possess no way to examine head Place!
I believe some powder measures work better than Some others. I've Lyman, RCBS, Lee and a single other brand name I can't try to remember at this instant along with the RCBS seems to be improved for me compared to Other individuals.
I don't shoot weighty bullets. Heaviest is 62g Acquire PP. Seriously I am looking at 55gr. I like accuracy, but gnats butt is just not a requirement for these.
2 grains and never exceed 3100 fps. The effects posted from the manual for a longer barrel do yield increased values, however it would seem that the value of your NATO ammunition in that barrel would generate even bigger values.
I didnt like Functioning up for benchmark or h335 all all over again, but now, h335 is my head over to powder, for my ar
Give up chasing velocity and exceeding Max load data for H335 loads as H335 will return you damage to your gun and maybe you, much too. It is unique in this regard, according to this post.
In the article the author did badly injury his gun (took place about twenty years back) while reaching for your little bit extra velocity applying data higher than the mentioned data. He stretched the load simply because he wasn't receiving the velocity he felt the cartridge was able to. In stepping up the demand in one/two grain increments, the load amount ahead of the detrimental just one, knocked the the journal protect open up and he disregarded that only to go to the subsequent action and established again the lugs about the rifle.
Scenario production approaches and annealing processes will even have an effect on how they carry out. Due to this fact, some scenarios will display indications of force before (typically sticking while in the chamber) than circumstances which have a more difficult or more durable blend of metals.
