You cross a certain percentage of piston diameter on any of the port widths, and you'll run into serious trouble. Same with changing the port roof. That's what affects your port timing - and it's all about port timing on 2-strokes. Only when you can't affect the port roof anymore, do you go wider, in a general sense. It gets much deeper, though... That's where the Black Magic that Ray was talking about comes into play.

They only affect rail height. Only. In the DPMS section, we have a pinned thread that discusses the TWO rail heights that will concern you. The third rail height is the High Rider. Don't think you'll find a blank High Rider to machine. Your head hurts because you're not listening to the accurate information that's being presented to you...

Nobody ever told me about that rule... :wtf: OP, welcome aboard. <thumbsup>

Nobody makes a DPMS Gen II upper, besides DPMS. There are no other alternatives right now. None. Therefore, you don't need to worry about getting a Gen I or Gen II upper that you can mill out. Hope that helps.

Slow elk... <lmao>

Any word from you peeps? I'm shooting anyway, but if you guys aren't coming, I'll wake up later... :))

Serious?!!? You sneaky bastages! <lmao>

Laser Cast (Oregon Trail Bullet Company) does some of these, too - thinking about trying them out. I'm using their 405gr 45-70 cast bullets, and the damn things are VERY nice! Hit the 45 Cal page and check what they have: http://oregontrailbullet.com/shop/

I've got 3 of those that are dedicated to The Woody. Love 'em. <thumbsup>

I ended up with 5 x 20-round mags, 5 x 30-round mags, and another titanium strike plate in my cart, by the damn time checkout hit me... <lmao>

Here's a 5.56 story - my most accurate "range ammo" for the 5.56 rifles would shock you. Every one of them is a 1:7 or 1:8 twist rifle, and each one excels with heavier loads. 68 and 69 grain loads, then 75 and 77 grain loads. For 100-yard range ammo, though, these things are surprisingly accurate with my own 55 grain range load: 55gr Hornady FMJ-BT projectiles, whatever .223 Rem or weird 5.56 NATO brass I have (Lake City gets saved for other things), CCI 400 primers, and 25.2 grains of Varget. That load rocks through a 5.56 rifle on a flat range. Now, that weight of projo shouldn't do as well through those twists of barrels - but it sure does. Know why? Consistency of the load, each time, even despite the variance in brass manufacturer. I'd load that stuff in a mag and take shooting bets on targets at 100 yards. <thumbsup> I just made another 55gr load with RL-15 powder, and it's working pretty damn good. I'll test more and post it up. Just be consistent, brother. :happydrunks:

Can't wait to see the results!

^^^ What he said - I swear by a timer. Only true way to see how you're shooting, with a real result that you can see. You can "think" you're getting faster and better (reloads, movement, etc), but unless you're timing shots, there's not a way to see for real what you're doing. <thumbsup>

I know, I know - but it's a badass trigger, brother... <thumbsup>

I received a surprise today, from a couple good people here - new Brother Beach sling! I'll get it on the 45-70 and get some pics. <thumbsup>

Those mags fucking ROCK! <thumbsup>

Bottom line - don't turn into a gear-queer. Shoot your fucking gun. <lmao> <thumbsup>

Brace yourself, here comes the harsh stuff. Don't take it personal, 'cause it's not meant that way... At your stage in the game, you shouldn't even have a reason to know what a meplat is (it's not a "meplate..."). Your concern over how the meplat affects shooting shouldn't even matter - it's not affecting you, at this stage. With lot's of reading on the subject - do more shooting, on the subject. With non-uniform meplats on Sierra 168gr SMKs, you should be able to shoot 1MOA at greater distances - on those inferior bullets. Many people do it, routinely. That's a point to make - you don't need to do anything but practice consistent reloading techniques with good projectiles, and have good accuracy at longer distances. You're not out there trying to win your National F-Class Title next weekend. If that comes in the future, then awesome. Don't stick yourself to 1MOA because I used that as an example - use 3MOA as your goal, master that out to 300 yards, and then do the same thing with 2MOA out to 300 yards. Whatever it is, set your goals. Gear and badass reloading equipment isn't going to make you a good shooter. Practicing the shooting fundamentals, mastering those, and outshooting your rifle is going to do that. After that, find the next limitation. If you reload consistently with good (appropriate) components, then your ammo isn't going to be your limiting factor for a long time to come.

45-70 Challenge is happening anyway - but that thing won't set off Tannerite. Too slow on the projo. I've got some $hit planned for the 45-70... picked up another 50 rounds of new unprimed Hornady brass tonight after work. Chamfered the inner case, tossed them in the tumbler, and they're all primed now. They'll get powder/projo tomorrow night. <thumbsup>

Dude, reload good projectiles, practice consistent reloading techniques, and get good at shooting by practicing the shooting fundamentals... Reason I state that is: You're all worried about super-accuracy. Let that $hit go, and stick to the basics. You just started jogging, and you're trying to find out how to be the best 1,600-meter Olympic sprinter, due to a certain brand of shoes that sprinters wear... Master the very basics first, with your shooting technique, AND your reloading technique. Outshoot your rifle, and your basic loads. Once you do that, determine if your rifle is your limitation, or if your reloads are your limitation. Adjust accordingly. You're trying to do too much, too fast, and I think you're going to be disappointed. You'll drop a Metric $hit-Ton of money in reloading gear that you don't need, and think that it doesn't work - because your shooting technique needs work. ***Example, don't get pissed off*** There's a logical sequence to all this, and short-cutting one doesn't necessarily give you benefits overall. Take your a$s to the 50-yard line, and shoot until you can nail a 1/2" x 1/2" group. Post those pictures. That's a 1 MOA group. Move to the 100-yard line and shoot a 1" x 1" group. Snatch pics. Move to the 200-yard line, and shoot a 4" x 6" group - figure out what the hell happened... Can you smell what I'm spreadin'?...

Ray, do I need to quiz this dude on 4-stroke Motor Math?... >:D

That's nothing like porting a 2-stroke engine in anything else. Tell me what you know about 2-stroke porting... I'll engage.

Brother, you tell me what you want blown up, and we'll do it. I need to find something to put over the top of the charge, so we can measure the vertical distance... I'm thinking a 5-gal Home Depot bucket would getting pretty far up there... <thumbsup>

That would have zero bearing in this situation. Logistics on your part need to be considered, of course, but at this point, you practically own this barrel, with review. There was a recent new guy that asked about a part, and even mentioned "the rule" in his post - his first post, or close - he spent more time reading and not posting, and was aware of it before making that post. If that new guy can do it, then... <dontknow> Let us know how it shoots. <thumbsup>

They shouldn't measure differently - they all have to follow Colt's TDP.
