Re: Savage 111 LRH 6.5-284 Loading Questions
Since I am running fairly high pressures in this tight chamber I am having to body size the cases and bump the shoulder .002. If I do this and keep the cases consistent the FPS is more consistent and am not seeing the flyers once a good load is found. For example if used any of the good loads the bullets kept hitting the same spot, shot after shot, and not throwing one here or there.
Before I did this I would have something like this. 2952, 2954, 2980. Now I will see 2940, 2940, 2936, 2942...... etc. Also the one with 2980 would leave an extractor mark on the case head and the bolt lift is tighter. Rechamber spent case takes some pressure.
I just body size with a Redding body and bushing size with a RCBS. My neck die is .292. I am on my 8th reload on this lapau brass and will anneal again after this next firing. Using my head space gages I am seeing a consistent measurement of 1.840 to 1.841. Those all have a slight pressure to chamber. If I bump to 1.838 to 1.839 the bolt pressure is gone. So I have set the die to 1.838.
New Lapau brass took two firings to get to the 1.840/1 measurement. I could likely get 3 shots before needing to body size, but I am unsure yet. I am still playing with my old brass and seeing how well it holds up after all the BS I put it through. Pretty impressed it has taken the beating it has. I have about 5 or 6 in the group of 60 that need to be culled. Primers are going in pretty easy now and I noticed a black ring on my bolt face. Those are probably leaking a little.
