100gr 6.8spc load on a 270

[ajacinto]

Howdy folks,

So I am in the search of a reduced load for my Remington SPS 270WSM. I'd like to try and shoot 100 grainers for this coming deer season. I've seen the Hodgdon® H4895® REDUCED RIFLE LOADS, but alas I don't have any of the Hodgdon powder.

Alliant's website has loads for the 6.8spc with a 100gr projectile under RL7 and RL10x. So now you know why I am thinking of shooting such a 6.8 load on my 270WSM.

Has anyone tried such a load, or a similar one? Alliant calls for 28.5gr of RL10x, compared to 62gr of RL15 for a true 270WSM 100gr load.

Any input is appreciated


PS:
I've heard rumors of low-powder-volume cases going kaboom, but most people tend to agree that such occasions are due to double/triple/etc charged loads.

I understand the differences between fast and low burning powders, which likely has a correlation on load volume. Anyhow what I am looking at is recoil.

JBM calculates:

25 ft*lbs of recoil for a 140gr with 65gr of RL22 [what I am currently shooting]
19 ft*lbs for a 100gr with 62 gr of RL15 [true 270WSM load]
7.7ft*lbs for a 100gr under 28.5of of RL10x [6.8spc load]

Just an update for whoever read this thread.

So it has been done before. Albeit its recorded as being done with cast bullets, the author does make some references to fast powder loads in standard sized cases.

Green light is a go! I receive my 100gr projectiles today, time to experiment with some RL10x
