Back in August 2015, Curt Lyles posted a response in a thread pointing out that he was having good results using Coconut Oil as his patch lube. I promised myself I would give it a try and finally got around to it today. I was prompted in large part by the threads we have had in this section of the forum discussing wiping vs. non-wiping.
The purpose of this post is to share some observations regarding the use of Coconut oil.
The rifle is a 40 cal. SMR with a 42" Rice square bottom rifled bbl. The load is 40 gns. 3f Goex. w/ .395 RB. My untreated patch material is .020-.021 (uncompressed), .014-.015 (compressed).
Until today, I have only used a dry patch which had been soaked in 7:1 water:Ballistol. Patch material then laid out to dry overnight. When shooting my dry patch, cut at the muzzle...I wipe between every shot with a thin "wiping patch" just damp with Moose Milk (water/Ballistol/Murphy's Oil Soap).
I have followed the comments of shooters on this forum with a lot more experience than I have, and decided to give NOT-wiping a try. Being here in Florida, and after reading Curt's excellent comments about the use of Coconut oil, I went for it.
I pre-cut 1 3/16" circular patches from my usual patch material. Saturated them in liquid Coconut Oil, then patted out the excess with paper towels. Left them on a flat tray overnight in the garage.
At the range today...conditions were VERY blustery. I decided to just shoot some 25 yd. offhand, using my precut pre-lubed ( with the Coconut Oil) patches without wiping.
I fired 10 shots at one 2 7/8th's inch bullseye on the NMLRA 6-Bull target. The Bull encompasses only the 8-9-10 &"x" scoring rings. All shots stayed in the black ( 8 or better), with 4-10's, 2 "x"'s. That is pretty good offhand shooting for me, so I was pleased with the performance at 25 yds. Moreover, Each shot loaded extremely smooth with the same resistance at shot 10 as I observed on the first shot. I was very impressed with the ease of loading and the consistency of the shots. No failures to fire occurred.
Here's where the questions start:
1.) I felt a definite "crud" buildup of some kind in the breech area of the barrel. I never experience that when wiping between shots.
2.) I routinely pick the vent between shots and when doing that on this group of 10...there seemed to be more "openness" inside the vent vs. the feeling I get when I have wiped prior to loading. When I wipe between shots, I have been aware of the need to use a reduced size "wiping jag, and a thin damp "wiping patch" to prevent fouling from being pushed down onto the breech face causing failures to fire.
After firing my 10 shot test, I cleaned the bbl. with Moose Milk wet patches, then dry patch, and fired some shots using my usual "dry patch" system, with wiping. They were fine.
I'm curious about the "Crud buildup" I felt in the barrel, and while I really like a lot of things about the Coconut Oil, I have a concern that not wiping is allowing a buildup in the bottom of the barrel.
There it is...comments requested and welcome.
Thank you.
