Going to Start working up a load for 39 grain Sierra's

[Squatting Wolf]

Now that I'm back from my trip, I am going to work up another load, this time using the 39 grainers from Sierra. I have a pretty good load worked up for the 32 grain Hornaday's usine 26.6 grains for H322.

I have 3 powders to try out which include H322, Benchmark & BL-C(2). I've checked Hodgdon's website but wasn't able to find data related to the 39 grain Sierras. I'm looking for the minimum and maximum loads for each of the powders, that way I can work from the bottom to the top, incrementing by .2 grains with each load.

I have found some information on the .204 Load Data tab on this forum and from what I gather it looks like for Benchmark the spread is from 23.3 grains to 25.7 grains. H322 is from 22.7 grains to 24.2 grains. I didn't find any data for the BL-C (2) powder.

Any info would be appreciated!

Squatting Wolf--I have had super good luck using 28.0 gr. of H4895 with the 39 gr. Sierra. I did find some decent loads for that bullet with H322, and Benchmark, but never tried BL-C2 with it.

Squatting Wolf,

I used the 40 grain load data for the 39BK. For my XR-100 I ended up at 27.7 grains of RL-15 and BR4 primers.

Squatting Wolf, the Hodgdon data shows 28 grain starting and 30 grain max for BLC-2. I was working on loads for BLC-2 with 39 gr. BK's but I quit at 29.5 grains because of pierced primers, see CCI400 primer post. 29.5 grains looked good 4 of the 5 shots were touching, 1/4". The 5th shot made for a 3/4" group that could have been my fault. I will try that load again but with a different primer. Oh yea the velocity was 2650fps avg. 29.5 grains didn't pierce primers but 29.8 grains did. I don't think the load was too hot just a thin walled primer.

Thanks for the info everyone. I'll have to get some H4895 at some point and give that a try but for now I've got a pound of the other three Hodgon powders I listed above.

Did you find that info on Hodgon's website or in their reloading book? I've been using Remington 7 1/2 primers with my load of 26.6 grains of H322 pushing a 32 grain V-Max and I've had good luck, no issues at all with the primers. A buddy of mine is using the CCI BR4 primers and has had good luck as well, I personally hate how much space a 1,000 rounds of CCI primers take up in the reloading cabinet!

Oh yea the velocity was 2650fps avg

must be a missprint?

[doctor duck]

Yea meant 3650fps, thanks for clearing that up. Squatting wolf, click 204 load data at top of home page here,then click Hodgden.

25.5 grns of benchmark @2.276 col with the 39 grn. bk has worked very well for me

[Squatting Wolf]

jwbagm - what kind of groups are you getting with the benchmark?

[jwbagm]

.3@100 all holes touching and this is in a new gun.
