225gr. ELD-M in 30-'06
@ 10:43 am (GMT) |
Paul LevermanJust another bullet/load combo tried for the heck of it. Rifle is a run of the mill Savage 110 with a re-worked Accutrigger, stabilized and bedded. Stock barrel. Magazine length 3.509", max COAL 3.478, loaded to 3.463" (-0.015"). Medium crimp from Lee die (how do you measure this?). Average velocity 2376fps (2401 - 2330) ten rounds. Average group 0.606" (#1 .727", #2 .631", #3 .482"). First group was shot in a not so good head wind and strung vertically. Hadn't even made it to the target stand and the wind died completely for the rest of the day. Go figure. I'm going to try a slightly heavier crimp on the next work up to see if I can tame the ES a tad. As it sits now, I would be comfortable to use this load out to 400yards which is four times our normal hunting distance. A good day. |

Anders ÖsterbergRe: 225gr. ELD-M in 30-'06Hello.How long in front of the muzzle do you have the cronograf...? Over 70 feet ES ...thats something wrong... If it's not a magnetospeed-chronograf I'd say you should have a minimum of 15 feet between the muzzle and the chrono , the muzzleblast gives false readings if it's to close. |

Nathan FosterRe: 225gr. ELD-M in 30-'06Hi Paul, typing on crappy spare computer, will keep it short.Might be a sweet spot at 2400-2450fps. SF powder normally improves ES once the air space is removed / higher charges. Some rifles will handle a range of powder, 4350 to 4831. Others need high bulk density slow powder but other than SF, it can be hard to find something around 4831 burn rate that packs down well. 4831sc can be crunched down a bit but not like a ball powder. If using ball powder, a mag primer can help with ES, same as the crimp. And yes, set the chrony out long, get finl readings on a cloudy day. Have used the 225gr at slow MV's, seems to work just fine without twist issues, fine for killing, may be a bit of bummer for transonic gong killers. |

Paul LevermanRe: 225gr. ELD-M in 30-'06Good morning gents. Yes, setting up the chrony is always a challenge. The law requires berms in front of the firing line, so it's tough to get it set up on the off-side if the range is busy.I was using a 4831 equivalent, and was at 102% density. After settling the powder in the case, would just get a slight crunch from the top layer. I've reloaded some identical rounds to try, this time with a slightly heavier crimp, just to see what's going to happen. If it shows promise I may try one more time, going even heavier. If not, I'll probably switch to SF. On a side note: buddy brought along his Winchester Mod 54 in 30-'06. What a dream to shoot. |

Warwick MarflittRe: 225gr. ELD-M in 30-'06Paul you could possibly use a torque wrench that we use for tightening engine cylinder head bolts to get uniform and a repeatable measured crimping force. They come in different sizes and measure in "inch pounds, Foot pounds, newton meters.You'd have to make it fit to use it for the handle on your press. Kiwi ingenuity is what we call it.... |

Paul LevermanRe: 225gr. ELD-M in 30-'06Warwick seems to me we discussed this last year sometime, and I made up an adapter. I wonder what I did with it? Maybe it didn't work. For now I've been using indexing marks to correlate the lock nut to the collet. Seems to work pretty well, it's probably not real accurate for increase/decrease, but it does seem to put a consistent crimp throughout the load. |

Thomas KitchenRe: 225gr. ELD-M in 30-'06HI PaulI believe me and you talked about this titan reloading do a product called consistent crimp https://www.titanreloading.com/consistent-crimp Which is pretty much you replace handle on press with a torque wrench. |
