IMR4895/WC846

[Ron Brooks]

I am planning on ordering some powder and bullets from gibrass and was wondering about these IMR4895 and WC846. As I understand things they would both be fine for my P17. What I am really thinking is that the WC846 is going to meter a lot better thatn the IMR4895. Is this correct?

Is there anything I am missing that would push me toward either powder besides the difference in metering?

Thanks

Ron,

Yes, with WC846 being a ball powder, it will no doubt meter better than IMR4895. If you're just producing blasting ammo for a 2-3MOA rifle, then by all means go with the WC846. However, if you have an accurate rifle and want to produce highly accurate ammo for it, then go with the IMR4895. Both M72 and M118 Match ammo were loaded with IMR4895.

USSR,

Thanks for the information. Looks like I'll be getting IMR4895 sincegibrass.com is out of the WC846 anyway. Pinpoint accuracy isn't a reality with me and the P17 anyway, although I have been wanting to get a nice 30-06 hunting rifle so....

Thanks again.

IMR 4895 is a really short grain extruded powder. It should meter better than most,though not as evenly as 846. If it makes you feel better,I've found my 4895 batches from Wideners to be much less temperature sensitive than my 846 or 844 batches.

4895 and powder measures

Yes, 4895 (even tho supposedly a short little rod) is sometimes a PITA in a powder measure and I've used three different measures in an attempt to deal with cut grains, etc. But, that powder works so blessed well in both my M1 rifle (.30-06) and my M1A (.308) that I could not give it up.

I finally bit the bullet and got one of those damned expensive Lyman 1200 digital powder scale/dispensers. With the right loading procedure it takes no more total time than just dropping powder into a case with a measure and it is very accurate. You get a weighed charge each and every time and size or shape of the powder granules is irrelevant. BTW, if I had it to do over again, I'd probably get the two-piece RCBS machine rather than my one-piece Lyman. Has to do with the delicacy of the scale and their warning not to turn the thing upside down to shake out the powder granules when cleaing up after a session.

cmr 100

and what about using CMR 100, does anybody have the data, for 165 or 180 grainers?

for what its worth, i've had great luck metering IMR 4895 (its my all around rifle powder) from a cheapie lee powder drop. everyone says plus or minus a tenth, so to sound like a parrot, this thing does about that well.

i've had great luck with IMR in 223 as well, so don't be afraid to try this powder in everything! i use it for 223, 22-250, and 270 all with pretty good results.

I have shot a lot of 4895 in .30-06 & .308 / 7.62 NATO .

I shot a little WC846 , had some problems and put it away .

4895 seems to be a lot more user friendly , seems to respond linearly to changes in powder weight / charge .

WC846 seems much more touchy . A dew grains difference causing an unexpected spike in pressure .

God bless
