Iam haveing a reloaded round chambering problem & need help Bad,,,i loaded some 235gr.speer .375 bullets today in new Hornady brass and the rounds would not let my bolt close,Can i seat the little bullet down even further?I feel like iam compressing my load all ready and wonder if iam jacking up pressure even more if i try to make the bullet seat further in?I did manage to fire a couple rounds and they were accurate and showed no signs of being to hot/they just dont fit well at all. All i have done to the new brass was run em up in the full length die just enough to round up the mouths,ream & chamfer the edges,measure total length,i didnt try to full length size since they were brand new..Has anybody got any idea as to what my problem might be?

In any manner you can pull the bullet from the reloaded round and see if the case only fits the chamber.....this way you can be sure you're dealing with the bullet seat depth as the issue.

Thanks Vapo,I went back and rechecked everything and seated my bullets down more just a smidge and chambering was mucho better,I guess my rifle just doesnt like the speer 235 seated very far out for some reason....& is very picky with that bullet and COL ...
Thanks again

Be Very Careful!
You have done two things that are known to increase pressure.
1. deeper seating of the bullet.
2. bullet contact with the lands.
We don't know the exact effect of these singly let alone together.
Compressed loads, deep seated bullets, and contact with the rifling
are not "bad" things. And are techniques used sometimes. Usually separately.
However combining all three may be problematic.
Prudent reloading practice would be to reduce your powder charge
(I would recommend a 10% reduction). And work up slowly.

Quite right! The reason may be...... IF your cases chamber freely without a bullet, and seatng the bullet deeper makes the rounds you loaded chamber OK, it seems to me that it is likely that seated long, the bullets were out so far they were hitting the origin of the rifling before you could close the bolt.

Try using a couple of resized, unprimed empty cases with that bullet. First, seat it the way you seated the first batch that would not permit the bolt to close. Try them. I'll bet they won't let the bolt close either! Then seat them successively deeper, until you find the length they can be and still close easy. Record this o/a length. This is your max o/a length for rounds loaded with that bullet. Adjust powder charge accordingly, IF NECESSARY!

The ogives of many bullets differ in taper. Therefore it is possible that bullets of identical weight, even, will require quite different seating depths......

I did just as you suggested El Deguello & made up a dummy round on the new brass that i know will chamber without a bullet.I went back and measured a Hornady Factory Loaded 225gr. round and the overall length is the same but the Hornady spire point is much sharper at the ogive area.I just loaded these new rounds to starting loads anyway and have about 4 grains to go before hitting Max recommended load.I feel better now after triple checking everything. Thanks

You have re-discovered that the distance from the rear of the case to the tip of the bullet is somewhat insignificant when finding the minimum seating depth without touching the rifling. The bullet shape (ogive) determine how far you push it in for each rifle. For

example ; the Speer 235 semi spitzer seated to achieve published OAL would probably jam into the rifling on many .375 cal. rifles were a spire bullet of the same or greater weight would not.

The max. OAL is generally determined by the magazine length. roger

Blackbearhunter try the Hornady 270 gr. round nose in your Steyr, it is working very well for me, I had no luck with 235 gr.Speers at all or 250 gr Sierras ran into same problems you did.

Why not? Cause you figured the factory did it for you?
