My newly chambered 375 Whelen Improved seems to have too short of a throat. I loaded some dummy rounds using Nosler 260 grain partitions and when I chambered the rounds the bullets got stuck on the lands. How hard is it to cut a longer throat? How much longer should I make it? Advice on reamers? Thanks. | ||

Quote: Do you have room in your magazine witht the dummies loaded? If not throating will only help if you shoot single shot. With an overall length gage and a comparator establish OAL to bullet ogive. Keeping limits of your magazine in mind calculate preferred OAL to ogive of your desired bullet. Buy, borrow, or rent a piloted throating reamer. Put a stop collar at desired OAL. Carefully rethroat. | |||

I use a throating reamer for my .375 H&H and built an extension and stop collar onto it. I hand load the round I wish to use.....in my case the old steel lined 300 grain solids from Hornady that I still have a ton of.....and throat the lands until the rounds have about .03 of clearance. I do this with the barrel in the lathe. If you want to send me your barrel and a loaded case with no primer and no powder I'll throat it for you and return the barrel | |||
