Thread: Acceptable variation in powder charge

I've been reloading for my t3 7rm for awhile now, using the now out of production IMR 8133 with good results but i find it doesn't run through my powder measure very smoothly and gets hung up in the tube.
But if i pull the handle down and give it a couple of taps then a couple more taps with a large bolt (LOL) it comes out with pretty consistent charges. I check the charges on my scales every 4 or 5 cases and it varies by about 1/10th sometimes 2/10th of a grain so is that variation enough to cause accuracy issues.
I tried under loading with the powder measure then topping it up on my scales with my trickler(a teaspoon) LOL but that is very tedious and prone to spilages. cheers
