    Wilson Arbor Press w/ Force Measurement

    Agreed. Just do not understand why measuring the loaded round does not yield the same answer.

    Wilson Arbor Press w/ Force Measurement

    The diameter of a loaded round is 0.292". I used a 0.290" bushing figuring that would give me 0.002" neck tension. I measured a fired case and the diameter is 0.295". After sizing the diameter is 0.290" so there is no spring back I am using Alpha brass. The brass thickness is 0.0155". If...

    Wilson Arbor Press w/ Force Measurement

    I recently started using a Wilson bushing type full length sizing die along with their bullet seater. I also used the KM arbor press with force measurement. Loading 6.5 CM it took 150 lbs. to seat the bullet. Also, the bullet press was not smooth. I would pull the handle down and the bullet...

    200 Yards Ok to Run a Ladder?

    PRoblem is that to get meaningful SDs you need to shoot 10 rounds. 10 rounds per charge is a lot!

    200 Yards Ok to Run a Ladder?

    My goal is to develop 1000 yard loads. Even at 500 yards a 50 FPS variation results in 2.5" difference in trajectory (1/2 MOA). At shorter distances will measuring velocity be meaningful for finding a load that will have most stable velocity (i.e. least sensitive to charge variation). I...

    200 Yards Ok to Run a Ladder?

    I am developing a load for my 6.5 CM. Is 200 yards far enough to do a ladder test or what is the minimum distance.

    6.5 CM Bullet Comparator

    I am beginning to load for 6.5 CM. My Hornady bullet comparator kit does not have an insert for 6.5 bullets. They have a #4 - .25 & #6 - .27. The kit indicates that there are six inserts which I have but there was no #5 which I'm guessing would be for the 6.5. I used the #4 - .25 and guess...

    MPA BA - Can a AW mag be used

    Just bought a MPA BA PMR Pro Rifle II. I knew it came w/ a AICS mag. Everything I read on the Coup de Grace action indicates that it does better w/ the AW. Also, on the MPA chassis spec it indicates that the BA chassis can be set up for AICS or AW. What would it take to convert to a AW mag...

    MPA BA PMR Pro II Barrel Break in

    12 weeks. When I ordered they just ran a batch of the PMR II in 6.5 Creed. I think I missed the batch but since this caliber is so popular, I was at the top of the list for the next batch.

    MPA BA PMR Pro II Barrel Break in

    I ended up shooting three founds cleaning after each round, then shooting 3 rounds & cleaning, shooting five rounds and cleaning, and then shot 25 rounds & cleaned. After the 3rd round I did not see much copper fouling which is why I went to 3 rounds, 5 rounds and then 25. After the 25 there...

    MPA BA PMR Pro II Barrel Break in

    I just got my MPA BA PMR Rifle II in 6.5 Creedmoor. Reading through their manual they recommend the following for a barrel break in procedure: This seems pretty intense & more than what most on this site do. Those of you that have MPA rifles, what kind of break in have you done?

    Teslong Bore scope

    Thinking about getting a Teslong. Primary reason is to inspect chamber to make sure a carbon ring is not forming. Any other real benefit? Don't want to go down the rabbit hole of seeing things that were always there but I did not know about and thus did not bother me. Also, a lot of models...

    6.5 Creedmoor Loads - Hornady 147 gr ELD-M (H4350 and RL16 Preferred)

    Just ordered an MPA rifle in 6.5 Creedmoor & will start developing loads for a 147 ELD-M & 4350. Will start with 40.6 gr. & go up in 0.2 gr. increments to 42.6 gr. shooting 3 rounds per charge. Is 200 yards long enough to shoot a ladder? I can only shoot steel past 200. Probably 3 months or...

    Accuracy of RCBS Charge Master 1500

    Will the 50 & 100 weight that comes be good enough or do I need a more refined weight set? My temp should be fairly stable. The only local heating may be from the heating that comes from the weight scale itself. on a given 'lot' I do not think there would be significant variation. Between...

    Accuracy of RCBS Charge Master 1500

    any Idea on a 308 what kind of velocity variation in ES & SD a 0.2 gr. charge variation results in? What about on a small cartridge like a 5.56?

    Accuracy of RCBS Charge Master 1500

    Yep, I was estimating that my deviation was in the 0.2 to 0.3 ballpark. I usually drop 0.2 gr. low and then use a manual trickler until the scale just bumps up to the target weight. For example, my 178 gr. 308 load is 43.0 gr. of varget. I set the chargemaster to 42.8 and then trickle. As...

    Wet Tumbling / SS Pins

    So using just dawn/Lemmeshine will clean brass or do I need the Frankfort stuff? I will start doing a light chamfer on ID/OD

    Wilson Seating Die - Now Need Arbor Press

    Just bout a Wilson bullet seating die not realizing that I would need a arbor press. Might just buy a Forster or Redding micrometer bullet seating die, but at this point just curious. Should I get a arbor press & try the Wilson die? The regular press is $150 or one with a force gauge for...

    Accuracy of RCBS Charge Master 1500

    For my precision rifle loadings I weigh all of my charges but use a RCBS Charge Master 1500. This will weigh charges to a resolution of 0.1 gr., but I worry that the actual variation is greater than this. My velocity SD & ES is not where I would like them to be & I attribute a lot of this to...

    Wet Tumbling / SS Pins

    I wet tumble my brass. Should I chamfer the case mouth ID/OD after tumbling?
