Got mine today!
Initial impressions, at least for my example of one Model 38 Cooper; Stuck in first case and cammed the bolt closed, lifted the handle and was stuck. Hammered bolt open and tried another case - same deal. Looked at case closely, hmmm, looks like a 20 VT case. Full length sized cases, now they cycle but still sticky. Loaded a case (sans powder), kinda dented the bullet and it won't chamber. Measured neck thickness at .017-.018 vs .014-.015 for my necked down .221 Fireballs. Turned all the necks to .014 Loaded a 32 Nosler bullet without squashing it and now it chambers . Primer pockets are dirty but crimp is swaged out. Seems necks are initially too thick for my 20 VT but your chamber may be bigger. |

With all formed 20VT brass necks will need turned. Regardless of chamber.

Got mine today, as well. These have NOT been neck turned. As Adam stated, neck turning this brass is mandatory. At a quick glance (I am at work), they appear to be nicely formed. The next question will be whether or not they have been annealed as that will affect the neck trimmer setting. I am hoping to give these a better inspection this evening, time permitting.

I got my brass today too. I measured the necks on 10 cases and they averaged .0135 on one side and .0140 on the other. Length was in spec. I chambered them and they stuck when extracting. I had to pound the bolt with my fist to open it. I neck turned the cases to .012 per side. They chambered and extracted normally. The cases were clean and well formed.
The primer pockets were dirty but swaged. The pockets were snug. I loaded some of the cases and bullets seated normally. I loaded the cases with 18.5 gr. of RL7 and Hornady 32 gr. Z bullets. I will shoot these as soon as I get a chance. I did not anneal any brass. I did full length size the 20VT cases and did not loose any. I will anneal them after fireforming. After the first firing I will neck size them with a Wilson 17M4 die with a 20 caliber bushing. I have been using High Plains 221 Fireball brass for 20VT. Forming from .224 to .204 requires annealing before sizing or I get split necks. Groups with the reformed 221 brass average in the .300's for 3 shots at 100 yds. I expect the 20VT's to do the same. I am shooting them in a Savage Striker pistol with a McGowen 16" barrel .800 at the muzzle. Velocity averages 3450 fps. with the above load. Tom |

I sent High Plains an email with my initial impressions, mostly positive. I did ask if, and when, the cases were annealed during the forming process. Will post reply when received.

Got mine also
Haven't shot it yet but FL'ed and seated a bullet just to check and it measures right at 232 so didn't bother trying to chamber one as my rifle is a 232nk. Thinking that number is right on for resized LC. Quality looks good and I'll load some up after I get the K&M out. After going through all the hoops with 2 sets of sizing dies I would rather go with these than what I make.

I don't mind neck turning but, seems many guys HATE it with a passion. If it is not going to come neck trimmed, I think the price is going to be critical to it's success.

Thanks for all of the feedback so far.
The cases aren't annealed or neck turned. Most likely we would emphasize this fact in the product description in order to keep the price lower. Around what you'd expect to pay for once fired. Annealing might become an option in the future.
