100 gr..257 Sierra Pro-Hunter load.

This is for a .257 Roberts. I bought a Lee 3 set Reloading Die. Haven`t reloaded for 30 some years. My old Powder Scale went wacky on me and there is a powder scoop included in the Die set. It shows that it throws a 39.5 charge of IMR 4350. Is this a hot enough load for Whitetail use for the Roberts? Or, should I step it up? The Rifle is a 7600 Rem. Pump.

Always check a current loading manual. Having said that, if I recall 39.5 grs. of IMR 4350 w/100gr. bullet in a 257 Roberts is on the low end of the data chart for that particular powder/cartridge. For what it's worth I've used 45.0 grs. of IMR 4350 in a Roberts w/100gr. Spitzer bullet. It's close to or at max in most rifles and does the deed on PA deer quite nicely.

Personally, I'd invest in a new powder scale.

Re: 100 gr..257 Sierra Pro-Hunter load.

I would most definitlyinvest in a set of scales. In a strong gun like a remy but be careful with a pump i would start 2 grains less than the max load. I have several 25's and that is an awsome bullet. I actually took a cow elk last year in Colorado 1 shot in the [censored] at 450 yards with the 100 grainer.

Looking at the Hodgon' s reloading center 39.5/IMR-4350 is less then the recommend starting load for the Bob w/100

Cartridge: 257 Roberts 100 GR. SPR SPBT IMR 4350
Start 44.8 2896 38,400 CUP
Max . 47.7 3077 47,000 CUP

Re: 100 gr..257 Sierra Pro-Hunter load.

I would possibly trust a powder scoop/dipper to add powder to a scale.I like using my RCBS powder trickler.I have a digital scale I calibrate every reloading session that I use it.I don't need gun metal in my body.For muzzle loaders you go by volume not weight.Everything else goes by weight.I'm sure I have no idea of what the weight to volume is for all powders.You most likely don't either.I also don't see how a dipper could measure a tenth of a grain.You could be over or under your desired charge by several grains.That could be bad.That's me though.

Buy a Lee powder measure kit... it goes from .3cc's to 4.3cc's.. also comes with a slide scale with a bunch of different powders and dippers. if you're just a hunter. If not get a scale and powder measure.

do the homework before the hunt

I like the Lee products. They have a scale that isn`t too expensive and the ratings, Cabela`s, sre good on it. But, the Dippers might be a good idea????????
