Can this powder be used in my pacnor 45 ? If so what amount would be recommended for a saboted 200gr bullet load or a 275gr sabotless load ? Since I already have this powder on hand I had to ask.
Thanks

Thanks smitty You could use the Bad Bull load with the 275 grain bullet. 140 grains of powder at 3100fps OUCH! Seriously if you are going to use 4350 at any reasonable speed you will have to duplex. A 10/50 duplex with the 275 grain bullet is a good starting point though it may be slow. But if that's the case you can add booster heading toward 15/45. The best speed for accuracy is probably about 2400fps or slightly less. Imr-4759 or N110 make good booster powders but Xmr-5744 will work as well. A 65 grain duplex could exceed 2400fps if you want more speed. And as you can tell by the Bad Bull load (which really is their recommended load) almost any speed is obtainable. With a 200 grain bullet it will work as well but I have not given much thought to a load. The load would be similar to any duplex given here but would require slightly more booster to reach the correct speed as compared to say a Xmr-2015/N110 duplex because 2015 is a lot faster powder than 4350. |

RB, Thanks for the great info. I'm not looking for punishing 45 caliber load like the Bad Bull and since I've had such good luck in my 45 so far with a single powder loads I see no need to duplex yet. I know this is changing channels but since I plan on adding a pacnor 40 to my collection soon I have to ask. What about using Imr 4350 powder for 40 cal sabotless (200gr bullet) load  ? : ) Sorry to be a pest but I'm taking notes while I have one of the teachers attention ! smitty |

I am currently using H322 and Varget in my 40, but 4350 sounds like it might be a good choice too. 375 H&H uses 81 to 85gr of it with a 220gr bullet at about 2900fps. What about a ML10-40? How about it RB? Class is in session and the students are listening. . . . . . . . . . . |

You got my attention. I am currently using H322 and Varget in my 40, but 4350 sounds like it might be a good choice too. 375 H&H uses 81 to 85gr of it with a 220gr bullet at about 2900fps. What about a ML10-40? How about it RB? Class is in session and the students are listening. . . . . . . . . . . I'll answer (or try) your question if you will answer mine. First everyone should know for larger calibers (yes a 40 caliber rifle is large for smokeless) 4350 in any of the 3 versions is slow, really slow. The only data I've seen for it in 40 caliber is a duplex of 9/71 to 10/76. The 200 grain bullet speed runs from 2850 to 3100fps. The 10/76 load is perhaps slightly higher pressure than desired but the load shows 3000fps with normal pressure is available. But this is a duplex. How does it work as a single? That's hard to say the only case to regularly use it in the 40 caliber bullet is the 416 Weatherby Magnum and it requires 122 grains of powder to reach full pressure with a 300 grain bullet. We are using a 200 grain bullet so it would be really slow. Still from the results of the duplex loads already reported a load in the 90 to 95 grain level would seem to be workable for 3000 to 3100fps with a 202 grain bullet. However I have not tried to reach it so the load would have to be developed. I think the powder you are using now (Varget) is more likely to reach pressure at a suitable level. So my question is how much of it have you shot. What was the load and bullet speed. Do you know the powder column length? Oh, sorry I guess I have lots of questions. |

Varget loads I have used is the 70gr. 5 gr 4759 below 65gr of Varget. With a 200gr bullet it is clocking about 2750' and the 100yd accuracy with the XTPs is well under 1". Straight 65gr loads of Varget alone with the same bullet are about 2250. So far I suppose I have gone through a bit less than 100 rounds of them, mostly with the "duplex" version.
I now have some resized 41mag 210gr SP REM bullets and plan to be squeezing some 300gr ones later. I would suspect that the 4350 might be a good bet with those heavier bullets, but it might be fun to try some light speed 200-210gr ones as well.
Not at all sure the Arkansas deer really require that much killin' but what the heck, a hobby is a hobby! Who knows, one day I may just "go a-huntin' fer a bar."
