AR2213sc

Mario RibicicHi gents,Quick question. Can I use ar2213sc in 130gn or should I stick to ar2209? Shooters on the net are using up to 62grains apperently. I will be reloading 150gn mainly with above powder. Chrony has been ordered so it will be interesting to see what powder charge will I need to acheive 2850-2900fps in the CZ. Regards Mario |

Nathan FosterRe: AR2213scIf we are talking .270, I have written about this countless times on the forum and related my experiences via the cartridges book.Much depends on the barrel length and throat length of the rifle. It takes a long barrel and long throat to make the most of 2213sc (H4831sc) burn rate in the .270. Even then, this powder can at times be dopey and unresponsive. This is why you see cases filled to cornflake crunching charge weights above 60 grains. In contrast to this, 2209 (H4350) tends to be highly responsive, boasts excellent speeds and accuracy- but without being reliant on X throat length or Y barrel length. In either case, we sometimes have to go well above book max to get the best out of the .270 Win. Hence the steps provided in my reloading book. Just keep in mind that the reloading manuals do exercise caution for good reasons. Try that 62 grain 2213sc load in the likes of a Browning with a "oh, were we supposed to cut the throat as well?" chamber and its bye bye rifle (and vision). |

Mario RibicicRe: AR2213scHi guys.Apologies for not providing a detailed question. I know you're a busy man Nathan. I do like your funny approach to damaging your rifle and vision. Yes its a 270 with 24" barrel Coal for 150gn BT's is 87.20mm Coal for 130gn BTs is 86.61mm 2209 is more readly available where I live, but everyone I know brags about 2213sc so I thought I'll give it a go. Apperently less pressure to acheive same fps. Thanks again. Mario |

Thomas KitchenRe: AR2213schi mario.i have learnt a lot of this forum and so much from nathan's books but one thing i realize sometimes you just got experiment with things yourself. i would get a nice accurate load working with 2209 then your can move on to 2213sc from there. im playing around with 2213sc in my tikka but need more range time to work out if i get better velocity. im also playing around with 2206h with 110gr vmax's |

Mario RibicicRe: AR2213scHi Thomas,Tell me about it. I've told all my mates about this website/forum. Hold that forend article has completely changed the way I shoot. If I can work out how to post photos Id put up a group of myself shooting off a bipod with arm crossed compared to shooting off a backpack and rolled up picnic blanket. I started reloading because of this forum. My groups originally were 1.5" avg sometimes 1" depending on the day, now with hand loads its down to 0.88" avg. Between family, working away it's been a challenge finding time to go down to the range. Cheers Mario |

Nathan FosterRe: AR2213scHi mario, your rifle specs sound good for the task.Yes, 2213sc should in theory boast lower pressures but keep in mind that the differences are not huge. I would suggest that if you have 2209 on hand, start with this. If you do not achieve your goals with acceptable pressures, then perhaps experiment with 2213sc. Many will ask, is it worth chasing the last 100 or 50fps? Well, its a yes and no type of question. When we carefully work up loads for the .270, we can often boost velocities by 250fps or more past standard load specs. In this regard, the question then becomes- where do we stop? Providing we are staying within safe pressures and enjoying the process, we may well want to take these experiments through to their final conclusion. |

Charles BrabhamRe: AR2213scI am not convinced of the wisdom in developing loads at or near the limits of what the cartridge and firearm together can produce. - You get short brass life, throat erosion issues, the possibility of dangerous conditions coming up on a hot day, and by pushing safety to the last point, there are numerous small mistakes and misadventures that can jump up to bite you.All of us know how to be careful, but none of us are in charge of Murphy, and he will occasionally have his way despite our best intentions. So, this is just me, but I get maximum 270 Winchester velocity - by using starting loads in my 270 WSM. By having the 270 WSM loafing along at 270 Winchester maximum velocities, my brass lasts longer, and Murphy has a little room to play his pranks without anybody getting hurt. A hot day is less likely to result in unsafe pressure, and the throat area of my barrel does not get the blow-torch treatment quite so so badly. I have owned a 270 Winchester in the past, and thought it did a great job one notch down from the maximum listed loads. When I found myself wishing for more velocity with the same bullet - I bought a magnum. Again, this is just me, and I am aware that my way of looking at things is not popular. Most shooters want the most that they can get out of what they've got, and this is an understandable impulse. There certainly isn't anything wrong with that approach, which is popular for good reason - but it is not for me. Kind regards, Charles Brabham |

Thomas KitchenRe: AR2213schi charlesi see a lot of wisdom in what your saying but to buy a magnum to load it to non magnum velocity to me is kinder like dating a lingerie model just to hold hands. with my 270 win i found a sweet spot inside the manual recommended load and one above max load, i have no pressure signs, my barrel might wear out faster but that's just part of owning a gun. you'll see Nathan seems to talks about loading for accuracy not chase maximum velocity. just my way of looking at it to, i really like the idea of using a one magnum caliber down loaded and up loaded for situation thou |
