Tales from the Reloading Room

Found jam today with these Berger 205 Elite Hunters. Did a ladder test with Retumbo in ADG brass with a CCI 250. Hoping for 2950 out of this 26" 1:8.

Have my 6 rounds for break in and my one control round.

Do you shoot one before your ladder test?
 
I don't. I haven't ever seen a noticable difference on a velocity test between a cold bore and not.

On groups, yes if I'm trying to get a super small one. No if I'm testing real world situation. I want to know how to dope for that cold bore if needed
 
My friends... do I have some stories to tell! Looking forward to sharing the last couple weeks of data. Maybe in a dedicated thread under the advanced section!

Loading up some plinking 30-30 rounds. I was able to get my Hornady Lock N Load measure to throw a pretty consistent charge of N135. 27.5 is a good middle ground with a 20" barrel that gets me 1950 FPS with these Berry's plated bullets.

.002" isn't going to cut it with these 205's in the .300 PRC. .003" feels much better so far after loading up another ladder test. Will find out Sunday
