Re: Problemb with brass?

1. Check sized brass to see if it chambers first as has been said.

Chances are that is your issue.

You really need to use the Hornady tool or sinclair to confirm headspace if you do not have a "bump gauge" made for that caliber.

2. Take one that is hard to chamber, pull it out and reseat the bullet another .050 in and retry to see if it chambers. That will confirm a seating depth issue versus brass if now chambers.

Re: Problemb with brass?

My brother-in-law's .270 WSM Vanguard was jamming some 140gr Nosler BT's into the rifling enough to pull bullets out of cases when seated at the book listed max magazine length (I forget what it is). Strange part was some of them jammed tight and some didn't seem to touch but there wasn't more than a couple thousandths variation in overall length at the tip. Perhaps a proper to-the-ogive measurement would have been more revealing.

Re: Problemb with brass?

All loads worked fine. Didnt have any pressure signs at all. some closed tighter than others, but all ejected smooth as silk. The lightest loads shot way worse than the hotter ones. best 5 shot group was .924 including the flyer, w/o the flyer they(4 shots) measured.541 center of hole to center of hole

Re: Problemb with brass?

I did push an empty brass witha partialy seated(smoked) bullet to the lands. Then ejected and repeated the proscess 3 times each with 3 ttl bullets and brass. Each time I got 2.905 or 2.904. so I backed it off .015 for 2.890 and had a tight fit on about 10 rounds out of 25, so I backed it off ANOTHER .005 for 2.885. Thats .020 ttl. OFF the lands and still10 tight ones. Even using calipers, 20 thousandths should more than make up for SLIGHTLY different o-gives in 1 lott of bullets.
And yes I randomly grabbed 3 brass and checked Before I loaded them.
Im leaning more toward not properly adjusting my re-sizing/de-capping die, as stated by someone earlier. Ill play some more with my die and see what I can do, and post my findings.
Thank you for your replies and comments. They were a big help.

Re: Problemb with brass?

Are you setting your dies to cam over at the top of the stroke? You should screw the die in until it touches the shell holder, lower the ram and screw the die in another 1/8 to 1/4 turn.

Re: Problemb with brass?

I'll add that that from what I've done with the 270 WSM I have found it to be a big brass mover first round, your going to need a trimmer with this one right out of the gate, get the Lee trimmer, it won't set you back more than 16-18 dollars. I trim every firing or I get trouble, like locking the bolt and flowing brass into the bolt head. With new brass I have to fire form Win and Norma brass before going full tilt or it will cause problems also, Rem is GTG. I'm going to set mine to min spec on a head space gauge to try to get the brass movement down more, nice thing about a Savage it'll only take me a few minutes.
They shoot better going hotttttt!!

Re: Problemb with brass?

Do you have a custom rifle or factory? If it is a custom chamber, you may have too tight a neck unless you turn your brass. Just a possibility........Rich
