6BR load with 68 Berger

[lpreddick]

i found an old canister of n135 and tried it(32 gr) in my 14 tw 6 BR with 68 cheeks and YES!YES!YES! my supply is small, so i'll go slow. i know what i'm about to ask is a forbidden thought...mixing powders. i have a faint recall of seeing on this site years ago of a discussion re mixing n133 and n140 to arrive at a performance of n135. if i'm mistaked, please correct me. i have ample supplies of n133 and n140. i accidently mixed two powders once and survived but the brass was trashed, so i'm not one to foolishly experiment. is there any evidence to support this "blend"?

I skimmed through the posts and did not see any that duplicated what I am about to type. If I missed one, my apologies. So then:


If you liked the 68s in a 1/14 twist using N-135 and FC 205 gm primers the chances are you will love the column bullet using the same......all barrels are different but......where the 68 gr. did ok for me the 65 gr WEB did better and the column closely resembles the results I get with more expensive custom made bullets..........

i see a lot of loads.what are your groups like as fare size goes at 100 yards .also are your velocities quite fast say 3400 to 3500 fps.

N133 leaves a bit too much airspace in the cartridge. 31 to 32 grains of V135 fills the case to a slight compressed load....perfect!
Whatever accuracy you are seeing with N133 will only improve with N135. Use both over a chronograph and see the rather startling improvement in SD.

Let the target tell you what works. I don't get hung up on numbers.
