Berger to introduce 7mm 195 gr EOL Hybrid Hunting Bullet

[BigSwede]

Got to shoot today 7mm-300. Magneto says 3045-3060 Chrony did too for the 195's. Punched into the berger app and spun turret up 12 minutes and shot at 700 and printed about a minute low. Spun up to 21.1. And settled in for 3 shots at 1000yds. Great group but again a minute low. Was rushed and had to be to work but not sure the BC is as high as claimed. Today ~400 elevation 50*F 5-10 gusty tailwind@45*. Will just have shoot more to be sure I geuss
-- side note -- I do love my 7mm-300wm. gun)

Big Sweed, that's awesome! I have found the advertised BC to work for me and I trust your Magneto speed. What length barrel and what powder and charge if you don't mind?

Might want check your zero farther out like 200 or 300. What I mean is leave it at 100 in the app but see if your dial up is right at 200 or 300. This should make parallax and other 100 yard issues easier to deal with. If its off go in the app and use "zero height" at 100 to correct. For example if you are 1 moa low, just enter -1" for your zero height at 100. then re confirm drops all the way out.

Jeff,
Thanks for advice. I need and will take it all!! Learning more and getting better.

Wow, that's 100 fps faster than I got with a 27". H-1000??

A Barnes and a Berger are on different planets when it comes to bearing surface and bearing surface has a large effect on velocity. Most people can shoot a 215 Berger 50+fps faster than a 210 in a .30 caliber because it has a shorter bearing surface. Less drag equals higher velocity.

you likely haven't shot many lead core barnes bullets.... these were a flat base spitzer lead core... Yes they probably have a bit more bore drag than a boat tail, but the difference should be 50 fps or less... The rifle they used was a 26" barreled rifle, which approximates most of the barrels guys are using here. I'm seeing most guys at the 26" to 28" mark. My rifle has a 27"barrel on it and pressures up virtually identically speed wise to the barrel in the barnes manual...

Oops missed that ..
Yes H1000 and I got up to 74.5 grains which tightened things up with f215m primers beginning to flatten pretty good but easy bolt lift and no extractor marks ...seems to be sweet spot load. Things are jumping a good distance because I got them to shoot at mag length. I've got to measure the jump. My coal to meplat is 3.620+/-.002(bullet variation) It's working out pretty well with the 195's so far.

That $62.00 a box I paid has my back side a little sore about now! $65.00 more on 5 boxes, OUCH!!!

Same here, Darren. I'm all for supporting the co-developer/inspiration for this product, but the shipping plus "handling" profit on the USPS flat rate Priority box didn't feel too good either!

I was thinking the same thing...

I've shot a lot of the Barnes originals over the years and still have a few boxes of them. Most of them were in big calibers as the selection for them was quite pitiful years ago before they expanded their X-bullet lines and other makers came around. A lead core flat base spitzer will have a bearing surface at least 50% longer than a bullet like the 195VLD. That is huge when it comes to potential velocity. The boattail alone is .230" on the Berger and, without measuring one again and going off memory, the bearing surface is about .680". That makes the nose itself about half of the length of the bullet. I bet the nose length of the Barnes is around 1/3 of the overall length. I just measured a 250gr 8mm Barnes original (not overly heavy for caliber like the 195gr 7mm) and about 60% is bearing surface. The 195VLD is about 40%. 100+fps faster with 2/3 the drag isn't stretching things at all IMO when you take in to account the shorter bearing surface allows the bullet to be seated out considerably longer (over .300") effectively increasing the powder capacity several grains as well. It's just Physics.

BTW besides the copper fouling problem there is a reason Barnes grooved the X bullets to make the TSX's. Less drag and more velocity. The same thing Cutting Edge does and others have done before that. The mono bullets are still long for their weight though and tend to use up case capacity unless the barrel is throated specifically for them.

No doubt, the $15 paid for a $6 flat rate box was...... That was my first purchase from them and my last! Honestly, in trust of a fellow member. I thought that was going to be their regular price. 3rd Gen had/has them for under $46 a box. Wish I would of waited, I could of got a couple of more boxes for what I paid but.......

My shipment required a medium flat rate USPS box, which costs only $11.30 when the transaction is performed online (which is what I do in my business). The box only traveled across town in my case, so it might have been shipped more economically too, but I understand the ease of USPS flat rate boxes.

I was charged about $20 for shipping. Sure--there was some foam in the box and it was well packaged in the USPS supplied box, but I hate surcharges for "handling," which is simply just one of many costs of doing business. Where might such surcharges end (inventory flooring fees, facility "energy" fees, liability insurance fees, employee wages fees, business loan interest fees, etc.)? These are just a few of the costs of doing business and no different from the labor required to pack and ship a box!

Well...back to shooting (though I think it's quite valuable to compare notes about businesses, products, and value among forum members).

I'm not going to be able to quite make 3000 fps like most of the rest of you guys here. I have a lifetime supply of Ruger RCM brass (both 300 and 338 RCM) so I got 7mm-300 RCM chamber and throating reamers from Dave at PTG. I have a 28" Krieger Palma barrel (1:8), late model CRF LA Model 70, McMillan Edge (Carbon) A-3 sporter stock, CDiPrecision DBM, and a Vortex Razor 5-20x50 scope. I'd love to see 3000 fps but McMillan recommends 300 Win Mag as the max. for Edge technology anyway and the RCM is close enough to that limit. I don't really enjoy shooting heavy loads in my 338 Win Mag much anymore so it should be a nice rifle for me. Unfortunately, I'm in the middle of a family move and haven't found time to chamber the barrel yet. Hopefully I will soon and certainly in time for next year's hunting season! (No time to hunt this year. )

Will be interested to hear whether your 1:9 twist is able to stabilize these big pills at longer distances.

I got off about 4rnds at 1000yd f-class before we were rained out. No key holes, but thats not saying much. Stabilizer calculator says twist is fine at my elevation. Normally I shoot at about 3500ft but the 1k range is at about 6500ft.
