Any ideas on the cause?
Cartridge: 35 Remington
Bullet: Pretty much anything...have used 200 FTX, 230 Lead GC, 200 HP Custom swaged, Unknown maker (Sierra or Hornady) 200 RN
I have loaded this round for this particular rifle for a few years now with somewhere between 39.0 grains for the 230 GC bullets, to 41.4 (where I started when I got the rifle) up to 42.7 grains (latest charge I tried that shot the best groups) of Leverevolution for the 200 grain class bullets and I always get the exact same results: groups that are just below or right at an inch.
However, the gun as one idiosyncrasy that I have yet to be able to explain: the first cold shot will be almost exactly 2" below the group. EVERY time! Shot #2 and on will group beautifully! This is even on a cold, DIRTY barrel and not a cleaned barrel. I could certainly expect a clean barrel shot to be off from the group as I get that all the time with all my other guns.
I really only started to notice this while doing load testing and keeping my targets with written notes on them about the load that I was testing on that target. Started noticing that my very first shots were all 2" low.
Change bullets or powder charge during the shooting session? No big deal, they group just fine. But let the gun cool completely out and fire another round and it is back with bullet #1 at 2" low (did this the last time I had it out as a test).
Is Leverevolution that temperature unstable that a single shot warms up the chamber so much that the rest of the shots settle in 2" higher that the cold shot?
The only thing that I have not done is shoot the cold shot through the chronograph to compare against subsequent shots.
Come to think of it, I used to have an H&R .44 Mag that I had to wait for the gun to cool between shots or else bullets would climb high and right.
Still living under the curse, but one of these days I will shed this body, be clothed with an immortal one, and everything will be good.
