So, I have put together a 300WSM on a savage receiver in an XLR carbon chassis. The gun was 300WSM originally, but I replaced the barrel with a pre-fit in a Varmint Contour. I ran out the other day after getting it assembled and put some rounds through it to get sighted in and see what I could get out of it shooting Southwest Ammo 190smk. Now I am getting ready to hand load for it.
Well I have a Hornady OAL gauge and Bullet Comparator.
Here are the numbers I am coming up with and wonder if I should be concerned that my throat is short.
300WSM XLR/Savage 2.267 base to ogive
compared to my other 300WSM
FN-300WSM 2.328 base to ogive
for a difference of .061
Southwest ammo 190smk measures at 2.275 which means to me that in the XLR/Savage it is jammed .008 in to the lands (am I doing this correctly)
I thought that the Bergers liked to be jammed and the SMKs liked a little jump.
Measured some factory hunting ammo all 180gr and it measures at 2.200-2.210 base to ogive.
So is there a problem with a throat that is short? Am I doing this correctly? Maybe the FN is the problem, even with the loaded long SW ammo it still had a jump of .053. I never did think the FN shot exceptional, but I figured it was me learning. I also never hand loaded for it.
Notes: All measurements done a dozen time with the same results each time. Also I do keep the fired brass labeled and separated for each gun. I am not new to reloading, just new to reloading to this level of detail.
