What is the min.caliber for class 1 nitro. Regards,Shaun. |
||||||||
|
|

Group 1 Nitro · Minimum calibre .330 · Minimum Bullet weight 165grains · Minimum muzzle energy 2,900 ft.lbs. |

Not sure why this topic was moved here but rather than start a new thread... Can anyone who is shooting one tell me if the .338/284 and 9,3x53R make Group 1 energy requirements with standard loads? |
||||||||
|
|

As 416SW stated those figures are the bare minimum, if your rifle can exceed that then all is OK. But remember to keep 2 cartridges for examination should you be queried on your loads in a comp. rough calcs 200gn .338 at 2560fps 2911ft.lbs 270gn .366 at 2200fps 2902ft.lbs Cheers 93x64mm |

Hi, I don't think the 9.3x53R will make the grade. The 9.5x57 just scrapes in. The energy factor is where it will come undone. The 35 Whelan, 338-06, 318 Westley Richards are about the starting point. LesLeeSpeed. |

The 9.3x57 easily makes it to 3,100fps+ in a Model 96 Swede with handloads. Even higher in a Model 98. Mine ran: 270 @ 2,300fps 285 @ 2,200fps 300 @ 2,175fps In these figures, the 286 low-balls but still passes at 3,074fpe. |

Unfortunately in Australia the official rules state: "Ammunition is to be as close as practical to factory ballistics of the original ammunition..." ...so juicing up an inadequate factory-load to sneak over the 2900 ftlbs energy level is technically illegal for competition. The .444 Marlin makes it with the 240gr bullet though.... Quote: However like LesLeeSpeed I recommend the .318 WR for traditional reasons and the .338-06 in bolt-action rifles for practical reasons. |

Quote: Seriously is that an issue? If a handload meets the ballistic criteria. Quote: As the BGRC was setup to create target and range disciplines to provide purpose of use/jestifications for many classic firearms and calibres in case the banner authorities choose to try to ban many of these rifles/large bore calibres, I have always thought the .318 WR was the idea behind the minimum of the "nitro class 1". Since the orgination of the club of course it has become a very established and real target shooting discipline. No doubt that a 9.3x62 would qualify for nitro class 1. And in the absence of a .318, .338, .358 would be a good practical choice IMO. When I have shot it, I have used my .375 H&H Mag as that was the smallest I had for it. |

Hi NitroX, The 9.3x62 is a great choice for Group 1 competition. I use one myself. The OP's question was "Is it the minimum?" and will it make the grade? Yes , it does and does it well. LesLeeSpeed |

I am going to acquire a 9.3x62 barrel for my Mauser M03. Not a "classic rifle" but a good usuable plaform for the calibre/cartridge. Hoping to trade in a .30-06 solid M03 barrel (near new) to partly finance the 9.3 barrel. |

BGRC experts Seeing the original question is well answered, can removable magazines be used for BGRC competitions? Never used my M03 for BGRC yet, but with a detachable magazine, it is difficult to load the rifle in the magazine. Where more than four shots is required for eg rapid fire competitions, would be far quicker to have a second magazine to load up instead. If this possible? Thanks. |

Not sure about changing the mag specifically however I believe they are currently looking at those rules. Eg mag changes and say having a mag that holds for example 10 rounds. For group 1 I use a BRNO 602 in 375H&H and it will fit 5 in the mag box and if you hold the rounds down you can slide one into the chamber. This works out well for the 6 shot competitions that are timed. For the 8 shot event (forgot the name) you need a reload. Personally I like the events where you are under time pressure and you have to do a reload. There is a lot going on in 30 odd seconds and it is nice to get them all away with acceptable accuracy.

Loved that about my 1970 ZKK602 .358 NM - 6 rounds - on a flock of coyotes on old Pete Andersen's ranch. When shooting 200gr. RN's at 3,100fps, it doesn't matter where you hit them - it's an instant kill. |

Quote: Have you thought about a 8,5x63 Reb barrel? |

Quote:Quote: You like it so much, buy one yourself. I would go for a .318 WR before that cartridge or a .333 Jeffery. Probably anyway. I wonder how th 8.5mm in reality handles the wide range of projectile weights? A 9.3x62 barrel would make a nice hunting cartridge for larger medium sized game, and running/driven game hunts. Already have barrels in 8x68S and a .404. A .375 H&H barrel might be another alternative but still have the issue with recoil and already have one in a Whitworth M98. |

I'm debating about the short action equivalent, the .338/284, though it would probably be cheaper and quicker to find a R93 barrel in 8,5x63 and have at it. Something smaller than the .375H&H appeals for Group 1 so my neck and shoulder unknot earlier in the following week.:D How do you find the .404 on the M03? |
