Cerakote impact accuracy?

[willidru]

When my customs 300 WM was being built it was coming down to the wire with hunting season and was either get my rifle or get it cerakote.

Obviously no functional benefits to cerakote but I’d still like the barreled action done. My questions are:
1. Will cerakote impact the bedding job? I can have him mask off the bottom of the action. I’m already not putting and coating on the bolt.
2. Since the action is assembled when it goes through the baking process will grease ooze out of threading and cause issues?

I would think that in most cases it wouldn't, but every blue moon, there's a rifle that's affected by the slightest change. Most likely it won't hurt the accuracy, but disassembly and reassembly *might* change POI. I would treat it as if I was starting completely from scratch after getting it back from the cerakoter, and hope that I'd be pleasantly surprised by nothing changing.

To answer your questions:
1. I’ve never seen a bedding job so tight that bake on Cerakote affected how the action fit.
2. Most times the accuracy will not be affected if everything goes back together the same way. Usually any affect on accuracy is not getting the action screws torqued properly on reassembly, which has less affect if the bedding is done right.

I have sprayed probably over 100 rifles and I’ve never seen oil come out of the action threads as long as I do my part with the prep. The trick is lots of acetone and pre-heating the barreled action to make sure there is no oil left in those areas.

Twice now I have completely disassembled my .243 to a barreled action, blasted it, sprayed it and baked it. Both times I reassembled the rifle My zero was only off by 1/4 to 1/2 MOA! That includes removing the scope mounts!

One is thing I did see affect accuracy is a local shop decided to blast a barreled action and didn’t find it necessary to plug the bore. A cartridge will not extract from a sandblasted chamber!!

Great feedback, thank you

Well put some Sniper Grey lipstick on her, slapped her back together with my new NX8 torqued and thread locker and ready to check and zero.


Bore sighted at 50 to get on paper and move close to zero with 2 shots, followed by 3 shot group at 100 with Factory Federal Premium and looks like accuracy is still there.



couple more adjustments, zero set and ready to move to distance. My concerns weren’t valid. Thanks @83cj-7

I would talk to Brandon if you have any concerns. He does custom paint for some of the bigger PRS and custom rifle names out there. He's a good guy and will give you an honest answer.

That’s a great looking rifle!

, Looks great. Glad it all worked out.

Thank you Sir, cerakote didn’t improve the functionality, but I sure do like pretty things.

Sorry, I missed that you had painted it already before I posted. That is good looking!
