Misfire ?

[timeout]

I had a young friend deer hunting with us that encountered a misfire with his 783 Remington, 7mm Rem Mag. caliber. The rifle had been fired about 10 times previously with no FTF's during break in and sighting. A quick examination of the primer told me that the firing pin had not struck the primer with sufficient force. I reinserted the round later and it fired. All I could do then for my friend was to remove the firing pin assembly and thoroughly clean the assembly (and inside of the bolt) with brake clean to remove any heavy grease or forein material and relube with a light oil. On checking the PTG website, I saw that they are making complete bolts for the 783 Rems. Since my young friend just bought the rifle and is going to school, his funds are limited. Have any of you heard of or experienced FTF's with rhe 783? I am hoping a new firing pin spring will solve the problem. When dry firing, the audible click sounds rather light. Thanks in advance for your responses.

I am not familiar with the 783. However, if the bolt function is like the Rem 700, a cause of FTF in the field can be an un-noticed bolt lift. I had that happen to me once. If he inadvertently raised the bolt slightly (i.e. caught it on his close while carrying) the firing pin energy is first absorbed in closing the bolt and then the remainder is applied to the primer. It doesn't take much to end up with a FTF. You might also want to check and make sure there is adequate firing pin protrusion.

Good Suggestion, thanks!

You may have already fixed it by cleaning inside the bolt. Keep dry firing it looking for jump in the bolt handle and different sounds. Since you took the bolt apart did you check protrusion while you were at it? I doubt that could be the case but look for things dragging slowing it down like the cocking piece on the trigger or one of those firing pin springs thats 3' too long crammed in there like a j lock spring was

I:m betting on aa slightly lifted bolt.

Had it happen to me a few years back. A buck was in front of me, settle the crosshairs, CLICK.

I thought the chamber was empty, so immediately cycled the bolt, and BOOM.

Afterwards, I found the initial round on the ground below my treestand. You could barely see a dent on the primer. Rechambered it, and you guessed it. BOOM.

It happens.

I did not check protrusion. I'll check that when I get my hands on the rifle again. Thanks for all the suggestion snd help gentlemen!
