These 133/135 Bergers shoot great and soar a while from a 7.5” twist, I’ve run them from 3115-3200+ in a 25SS at 26”, 72gr capacity.
I intend to give them a go at some point in the Mega case, 83grs, starting out at 3300-3400. It’s set up for monos right now, great velocity and precision and...
Guys, the n565 powder charges usually run the same as H1000. For comparison. It is temp stable., Usually 50-70fps more velocity than H1000.
568 normally needs a fairly roomy case to hit pressure, for me that’s been around 2grs more than 565/H1000. Also temp stable.
570 will get all there is to...
Yes, my daughters 25 mega would appreciate it also. The ABLR impressed me last season in .284 168gr and I’m looking to use them in 6.5 next season. Possibly .308 as well
N565 might be a better burn rate for those bullet sizes.?
I’ve done limited testing with a 25 Sherman Mega, 82-83gr capacity, it performed well with R23 with 100gr TTSX and 116gr apex gen 3 monos. N560 would sizzle, but it’s not temp stable.
Peterson brass is thick, definitely holds less than...
The new BT “ hunting” will solve any concerns you have with penetration, give better expansion and energy dump than a partition, and better precision to boot, with better BC.. I have killed plenty with 100grs at 3500+,and 115 grs at 3350+.
I shot a LOT of the old ones, so I understand exactly...
Don’t build a 28nos and run it like a 7PRC!
There’s always a suitable compromise based on individual needs, but those big performers are awesome when turned loose.
I spent several days in Mesa, late October. Visited Bruno’s and a shooting pal.
I enjoy the clean dry air, it does wonders for my breathing.
Prayers up for your family, safe travels.
I for one have no interest in extreme pressure arrangements just to have a sawed-off barrel and .473 bolt face.
What is the advantage here beyond having a “convenient” sized gun?
I’m ready to see the rate of barrel erosion compared to more standard pressure, and other pertinent data, from an...
Getting a 6.5 Mega to start loosening up, any day now. Plan to shoot 125ish grain mono’s for point and shoot to 325-350yds, in places I don't have time to range and click, like road crossings and narrow lanes.
83gr capacity/2.16” case.
.555 web diameter
A lengthened existing case design and reasonable freebore… not really pioneering there!
Not sure why they don’t embrace more girth, for capacity. So many benefits vs long and skinny, in my experience.
Maximum published data is usually conservative, considers any make and model, and these days, has a lawyer’s stamp of approval.
Your setup has its own maximum. Chamber size, brass used, bullet bearing surface and several other factors contribute.
Work up to it and be aware of the signs it...
