As mentioned, because you have good strikes on some ammo, protrusion should not be the problem. As used, my BTO reference is for the distance from the Base of the cartridge to the datum point on the shoulder. BTD is also used to describe this measurement. Too much shoulder setback in some cases could possibly cause light primer strikes as the cartridge could be setting further forward in the chamber than desired.

I would check firing pin protrusion for a start. Could be the LC cases have too short a BTO and are bouncing around in the chamber.

Had a friend visiting my shop, looking for information on the RCBS MatchMaster . While chatting about programming changes that are available on the device, I was getting some new brass ready to enter the system. Using a tool, I was deburring the case mouths inside and out before running them over an expander mandrel. My friend thought both the deburring and mandrel were not needed and that he had never done either after 30 years of reloading even on cases he had trimmed. His comment was the expander ball in the sizing die took care of both. No way. I showed him the difference, while bullet seating, using the different methods. He could feel the consistency of the properly prepped brass over the way he had done it for years. Ah yes, another convert. Neck tension is very important if you are looking to get precision from you loading. I love my Giraud trimmer and it has become part of brass prep during every loading. The Giraud in addition to trimming takes care of case mouth prep during the same action. Whatta Hobby!

Got out in the rain this morning for a final test of my load for Starline .223 brass. 73 gn Berger bullet over 23 gn of Varget set off with BR-4 primers. Decided that this really needs a dozen shots to settle down in a clean barrel. First 4 shots started out just under an inch to the left and as things warmed up they moved right into the X. Now, with the rain I can go down into the shop and load the 250 new cases that I have primed. Whatta Hobby!

Looking good. What a wonderful way to start the day. Thanks

Primed 300 new Starline .223 cases this morning before sunrise. Sure like working with this stuff. Whatta Hobby!

Found a decent load for my Uintah bolt AR in .223. Shot off bipod at 100 yds . Target is a MR-31C 600 scaled down for 100. 23 gn of Varget in new Starline brass. Bullet is a Berger 73 gn. Primer BR-4. Now if the trigger monkey would just do his part it would be one ragged hole. Whatta Hobby!

Shot one more for the halibut! Whatta Hobby!

I use an RCBS decapping tool, works like a champ and keep an eye out for KV 7.62N primers. They turn up every once in awhile. Not long ago Powder Valley found a stash and I picked up 5K for my use. Whatta Hobby!

I find them to be much more consistent and durable than others when used in my auto loaders. I believe the two flash holes contribute to better function. I have to admit that I use plenty of .308 and 6.5 Palma type brass with small rifle primers in many of my precision bolt rifles. Whatta Hobby!

Having more fun than a 75 year old retarded dude should be allowed. Whatta Hobby!

Ok. Finished the load development for this bullet. 150 flat base custom by Jerry Carpenter, .308 bullet in MEN berdan cases with tula primer over 43.5 gn of Varget. 9 rnds in .5 moa with one flyer making the max spread .75 moa with an average of .350. I will settle on this one out of an M14 type rifle for sure. Now, down to the bench to load up a few hundred. Whatta Hobby!

Great news.

Time to junk a bunch of LC, RA and DAG brass. Finally got up the guts to bring out a few boxes of new Lapua .308 brass out of the stash. Annealed it this afternoon and sized all 400 cases. First half has been sized, wet tumbled in the SS pins and is now in the dryer. Once dried it gets trimmed and them primed and ready to load. Whatta Hobby!

Our friend Art NeerGaard has a way of making purchases memorable. In addition to great ordered products he sends out pretty unique gifts. Most recent is his magazine dipstick. Simply drop in between case necks down to follower and you can tell whats left in the mag. One side is for 7.62/.308 and the reverse does 5.56/.223. Both go to 20 rnds. so you guys with normal 30 rnd mags will need to improvise. What a neat idea. Thanks again Art. Whatta Hobby!

Been taking them apart and putting them back together since USMC boot camp in the '60s so they seem fairly simple to me. My Rem 700 triggers have all been changed to after market too. Makes the game more fun , for me. Whatta Hobby!

Got in another Shootingsight NM EBR trigger and lightened hammer today. Used a brandy new Bula Defense Systems trigger group to install the parts in. About 10 minutes and parts are in, adjusted with screws loctited, lubed and ready for attaching to an XM21. I have a bunch of these in my precision M14s. Wonderful 2 stage take up and break that is pretty much permanent. No more polishing the old NM triggers for me. Art Neergaard has come up with a solution that really works. Whatta Hobby!

Loaded some RA 68 brass .308 with 150 gn fb over 41.5 gn of IMR-8208 and had to give it a go on my range. Whatta Hobby!

Rifle is a Bula Defense Systems M-14 type .308 rear lugged XM21 with ultra heavy 1-10 Bula barrel in a JAE Gen III chassis , Bula trigger group, OSS HX-QD .338 TI magnum suppressor, Atlas bipod , Accushot monopod. Scope is a Night Force NX8 4-32x50. Shot off bipod. Ammo used is RA 68 brass loaded with a 150gn Berger fb target over 41.5 gn of IMR-8208 set off with 210M primers. Whatta Hobby!

Shot a five targets this morning at 100 yds. Couldn't resist a chance with no wind in Mark's Hollow. Rifle is a CZ-457 with Timney 10 0z trigger, Lilja 20" SS barrel,single load adapter, S-7 bipod and Sightron SIIISS 10-50x60mm. She prefers the X-ACT at 100 yds even though it's a little slower.

Used the Rock Chucker in it's designated place this morning swaging 300 .223 Federal GMM cases. Having had it for over half a century, I had to find a use for it now that the Forster Co-as replaced it as my main loading press. Whatta Hobby!

I find the Forster Co-ax a much more user friendly press than my Rock chuckers. Love just popping the dies in and not having to use a shell holder. Just a better all around device for my uses.

I have used a Rock Chucker for over 50 years and not too many years ago I added a Forster Coax. One at a time is the best way for precision. I have been loading between 5 and 10 K of .308 for decades. Whatta Hobby!

Only thing today was to plunk down a 1K pieces 14lb box of new Starline .223 brass that UPS just dropped off.
