Well I did it I worked a load for the 6.5/55 arch imp. The load is extremely good (90grtnt---- 55.3gr----of imr4350)= three shots under a dime at 100yards .86 at 200yards and 1.9 inches at 300yards. I croneyed it a 3680,3666 and 3610 at10 paces.

IMpressive Load there Guy!

A little faster than I get in a 6.5 x 57 with that bullet. I am at about 3550 using IMR 4895 and 4064.

That 90 grain Speer is an accurate little bullet isn't it??

What barrel length are you using? What is the barrel twist? Barrel make (surplus or after market)


Thanks...
