    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?

    Once Fired Alpha Brass

    I just bought some Eagle Eye Ammo. Figured it was the cheapest way to get some good brass. After I shoot through my rifle, is there any special brass prep? Should I go to the effort of chamfering the hole from the primer to powder? Obviously I will check case OAL but if the case does not...

    73 ELD-M vs 75 BTHP for AR

    That has been my experience as well. Unfortunately, still not going to be enough to get me out to 1000 yds. My AR has a 22" barrel and my 75 BTHP leaves the barrel at 2830 FPS or so.

    73 ELD-M vs 75 BTHP for AR

    Does the 73 ELD-M have a real advantage over the 75 BTHP? The published G7 is .2 for the 73 & Brain Litz has the 75 BTHP with a G7 of .183. My MV is 2850 (shooting out of a 22" barrel). JBM has the velocity going subsonic at about 850 for the 75 & 950 for the 73. I have shoot a lot of the...

    5.56 75 ELD-M - 2.26 COAL???

    You guys convinced me that doing this would not be a good idea. My AR has a 22" barrel & that gets me out to 800 w/ a 75 gr. BTHP. Past that it falls off a cliff accuracy wise. JBM confirms that I will have issues past 800. I have a MV of 2850 FPS & use a G7 of .18 to get the dope to match...

    5.56 75 ELD-M - 2.26 COAL???

    I understand that the 5.56 cartridge was designed for shorter bullets. What is the downside in me shooting the 75 ELD-M seated deep assuming that it will feed? It chambers feed from a magazine & dropping the bolt just fine. I admit I don't like the excessive bullet jump, but other than...

    5.56 75 ELD-M - 2.26 COAL???

    I have been shooting the 75 BTHP for a while. It does not have the BC I needed to get out to 1000 yds,

    5.56 75 ELD-M - 2.26 COAL???

    When loading a 75 gr. ELD-M to a 2.26 max COAL, the bullet sits deep in the case. 2.6 COAL obviously to get the round to fit in a magazine. The bullet would have to be seated to a COAL of 3.03 for the full bullet diameter to be is the case. Looks a little odd. Any issues with seating a...
