Another thing that just now crossed my mind is I don't remember trying the cold clean bore shot with my new tight fitting Grease Groove bullets? I have done a TON of testing over the summer and its easy to lose track! I'm pretty sure my cold clean bore problems were coming from my sized Paper Patched bullets after steam cleaning? I'll have to look at notes and see. Steam cleaning thru the Snail and Patented breech/Powder chamber might not effect the tighter fitting grease groove bullets, patched round ball, and sabots? I am pretty sure my problems were with my sized and patched bullets? Again i will have to dig through my notes, and group pictures

Ok, just did some digging/investigating, The MAJOR cold bore shot issues WERE definitely with my sized (slip fit) Paper Patched bullets after i had steam cleaned through the Snail. I thought i had cured it by popping caps off and fouling the bore with just the caps, while i did have some successes with the caps it was a hit and miss deal, i also tried the Lock eeze moistened patch to simulate a fouled bore, again i had some success but it stil wasn't great. I wish i had taken better notes, but from what i can dig up through my pictures my new full bore Greased conicals were no where near as effected by using the steam cleaner through the snail, The cold bore shots were VERY close to the group, i was popping caps off first to try and simulate a fouled bore with these Full bore conicals as well, Again The cold clean bore shots were very close to my groups. The cold clean bore TOTAL TARGET MISSES were with my Paper Patched and sized bullets.

My best advice if you are using a steam cleaner through the snail and getting that first 8-10" of barrel at the breech end HOT by doing so, is to test and make sure the cold bore shot is right? In a hunting rifle Don't just take for granted that it will be there, test it and make SURE its there!
