Re: Short Action Customs .284 Build - Beautiful!!

Mark, thanks for the heads up today. Getting the funds together so I can give you that call. When you get a chance let us see some groups and a range report on how that stick does at distance. I know its going to be a shooter!

Thanks- Gray

Well we shot them this weekend at 650 and 750 and at 750 we were opening and closing the heart/head flappers on IPSC targets shot after shot. There were 3 of us there to witness this or else I wouldnt have believed it myself. On that day, I would say they were grouping around 2-3 inches at 750. Im not exaggerating even though it sounds like it. They are hammers.

Flounder, that sounds incredible... with world record benchrest shooters putting 2.5" groups at 1000 yrds with a straight .284, I don't doubt it a bit. I know y'all are loving those rifles, I want one so bad. You and Mark keep up the good shooting!

Re: Short Action Customs .284 Build - Beautiful!!

They are truly hammers. We were fortunate enough to be shooting down a lane that only had a few openings for wind and the spotter was giving the calls when the wind died down for us to take the shots. I guess after I left the other individual told mark he wanted one after seeing how they were shooting that day. I wish we would have had it on video because I still cant believe how well they were shooting. Its still hard for me to believe it and I was there. Once I get some time, Ill post up another picture of some 100 yard groups with both the 162 amax and 180 vlds.

Re: Short Action Customs .284 Build - Beautiful!!

I was shooting the 162 A-Max with an average velocity of 2980FPS and a SD of 6 FPS. 59.1 Gr of 4831SC. It was shooting 4.3 mils of elevation with around .7-.8 Mils of windage with a 5-7MPH steady/gusts.

I believe FlounderV2's .284 was about 1 mil more for elevation and about the same for windage.

He took some of my 162 loaded ammo, dialed down to 4.3 mils and nailed the centermass flapper on his first shot!!!!

Re: Short Action Customs .284 Build - Beautiful!!

Both rifles were shooting great, I like the speed over weight at this point. FlounderV2 was digging the 180's and for good reason. On command he was tagging the flapper. He would open it, then close it, shot after shot at 750. Looking through the spotter the vapor trail was extremely flat.

Also, he knocked over the target with his 180's!!! They hit hard at that range.

Re: Short Action Customs .284 Build - Beautiful!!

5 shot group at 100 yards.. The bottom shot was a re-sight in after moving the scope and is not included in the 5 shot group.. Maybe someone could run this through OnTarget since it wont run on my machine. Photobucket is being a pain.

Re: Short Action Customs .284 Build - Beautiful!!

What kind of velocity are ya'll getting with the 180gr VLDs? I've heard that you have to seat the 180 VLD lower in the short action due to bullet length and the round exceeding the OAL to feed in a mag. The trade off being less powder capacity, leaving the 180gr VLD unable to reach 2900fps out of the short action. Very curious to see how this is working in those rigs.

Re: Short Action Customs .284 Build - Beautiful!!

flounderv2,

What an awesome build. I like your components. A question about the Manners stock - how does yours compare to the Manners MCS-GAT? I'm debating whether to go with one or the other for my next build.

thanks,
Jason

Re: Short Action Customs .284 Build - Beautiful!!

Mark,
Really, really nice attention to detail. My question is, is the entire action coated after bedding, or just what we see above the stock, and if the entire action is coated, does this change the fit after bedding?
Thanks.

Re: Short Action Customs .284 Build - Beautiful!!

Ill go ahead and answer a few of the questions being asked.

<span style="font-weight: bold">Papagallos </span>- Yes that is the rivet for the Manners Mini Chassis. That is the way the stock comes from Manners so you would have to talk with them if you wanted something that was flush. Or you could have your smith work some magic to make it disappear but it doesn't bother me at all.

<span style="font-weight: bold">Goatphius </span>- These are long actions so we can seat the round as long as we want without worrying exceeding mag length. To push the 180 bergers to 2900+, you'll need a longer barrel or different powder. Im running 54.5 of 4831SC and get right around 2760 with a 27" bartlein 9 twist barrel. With the 162 Amax with 59.1 4831sc we are getting right at 2994fps.

<span style="font-weight: bold">Jayman_10X</span> - I dont have any hands on experience with the MCS-GAT so I wouldnt be the correct person to answer.

<span style="font-weight: bold">steelcomp </span>- Yes the entire action is coated in cerakote and it does not affect fitting at all as cerakote is extremely thin.

<span style="font-weight: bold">taseal </span>- That would be a question for Mark as component prices are constantly in flux. I can tell you that it took about 6 months to get all the parts in after getting them ordered. I know that he has had a few people wanting a .284 after seeing how these things are performing.

I'm a dumbass Short Action Customs the company not the rifle. Makes more since now sorry bout the misunderstanding. Here is a link to a short action .284 used for hunting and tactical competitions. He is popping the 162gr pills due to the reasons stated in my above post.

Re: Short Action Customs .284 Build - Beautiful!!

Mark,
I have a 284 that I just had built with a 27" Broughton bbl on a short action. I made a single shot out of it and had it built to shoot the 162AMAX. Only working on load development for it now.

I noticed that your load of 59.1grs of H4831SC seems pretty hot for the 162s. What brass are you guys using?? I have Winchester for mine.

My gun really seems to like H4350 so far. I have done most all of my load testing at 400yds and have had some nice groups. Some were 1.5"s and under for 5 shots. Most the time it shoots 5 shot groups in .5MOA or less.

I went out yesterday to get some actual dials for my scope and shot out to 800yds. I had a full value wind going from 8mph to 13mph and I was impressed at how accurate the JBM program was for my wind dials. The other thing that impressed me was I was still able to shoot 2" groups at 400yds in that wind. Whats not to love about the 284s!!!!!!!!!!

We are using Lapua brass. So far there are no real signs of pressure at this point. 59.1 seems to work really well.

We are using Lapua 6.5-284 brass necked up. With 59.1 grains of 4831SC and the 162 Amax, we are right at max load according to Quickload. Even being at max load we still are not getting any real pressure signs on the primers or brass.

Re: Short Action Customs .284 Build - Beautiful!!

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Special Delivery</div><div class="ubbcode-body">Mark / Flounder,

Have you guys tried Reloader 17 yet, maybe 52-53 grains worth? </div></div>

We know we could probably get another 75-100fps or so with RE-17 but we didnt want to deal with velocity variations due to temperature differences. Temps at the matches here range from -5 degrees to 105 degrees so having a powder that is that temperature sensitive was not something we wanted to deal with.

Re: Short Action Customs .284 Build - Beautiful!!

Mine gun and Double J's F-class open guns are .284Win. also. H4350 is a decent powder as is the 4831SC. We are both running the 4831SC behind a 180 Berger. With 56.0gr. in my 32" finish length barrel I'm getting 2870fps. and that was on a 21 degree F day. Should be right around 2900 to low 29xx's. I've shot the load on a 85 degree day with no problems and the accuracy is outstanding. Twist on our barrels is 1-9.

6.5x284 Lapua Brass necked up for the most part. Just for testing the loads and getting velocity readings over the chronograph I used Win. brass.

Re: Short Action Customs .284 Build - Beautiful!!

What would the benefits of going with 162 amax or 180 Berger be? What would be the intended application for both. I'm a sucker for heavier bullets, but if one performs better.
 
#79
Re: Short Action Customs .284 Build - Beautiful!!

Mine is strictly being used as a long range target gun. Usually the longer/heavier match bullets have a higher BC. If you can push them at decent velocities they will shoot flatter and buck the wind better. For a long range gun this is an advantage.

Also some guys are shooting the match bullets for hunting as well but not all.

Re: Short Action Customs .284 Build - Beautiful!!

taseal-

I was talking to Flounder and Mark about their rifles. At 750yd the 162's were 1 mil less drop, but the 180 Berger was still 0.5 mil less wind.

The reason that he and Mark are shooting the 162's is because they're still an excellent bullet, but they are appx 60% of the cost of slinging Bergers.

For taking them out and shooting inside of ~1100-1200yd the 162 still performs so well that it is a completely viable solution.

Re: Short Action Customs .284 Build - Beautiful!!

tasel,
I went with the 162s because I am using the shorter barrel (27"). I didn't feel I could push the 180s fast enough to get the advantage over the 162s. Another great bullet is the 168 Berger. They also really shoot well in the 284s. But like was stated above the difference is $25 a box for AMAXs and nearly $40 for the Bergers.

Mark and Flounder,
Thanks for the info on the 4831SC. I have a jug of it and will give it a try. I was only using around 54 or 56grs with mine so I will try steping it up.

I have not cronographed my H4350 load yet but it has to be pretty good. I am getting around .5 MOA at most ranges I have shot to out to 800yds with it for vertical spread.

Re: Short Action Customs .284 Build - Beautiful!!

I see Frank Green was kind enough to post on here too. I wanted to tell him "Thanks again" for his outstanding customer service. I had one of his barrels and we could not figure out why it was inconsistant for accuracy.

Even though Frank could find nothing wrong with the barrel he replaced it with a new barrel of my choice at no charge to me. With that kindof customer service his company will have a lot of success in the future with shooters in this sport. THANKS AGAIN FRANK!!!!!!!

Re: Short Action Customs .284 Build - Beautiful!!

I have to say the Bartlein Barrels are absolutely great and probably all I'll run going forward! And the best part is, it seems to be picking up speed now that we have a few rounds down the barrel.

Thanks Bartlein.
