.270 150 gr. ABLR range day

[Silentstalker]

I will start dry fire practicing too. I have never done that.

I do a couple of dry fires before each group at the range if I haven't been doing much shooting as well.

So a quick follow up to my load development. Looking for thoughts and insight again!

I checked my rifle thoroughly, nothing is loose and it all looks good to go. I practiced dry firing and will continue to do so. I reloaded up 3 sets of 3 of 150 gr. ablr with 55 grs. H4831sc and reshot it at 100 yards to verify my previous results. I had a 7/8" group, a 1 1/4" group and a 1 7/8". No where near consistent. I then shot my current 150 gr. BT load that consistently holds under an inch at 100. This 3 shot group came in at under 3/4" fired quickly with no cool down period between shots. It did not disappoint. 1st two shots touching and the 3rd low and right.

Question #1- Do you think my rifle just does not like the ABLR with the H4831sc?

Question #2- Should I run my BT load out to magazine length (currently saami) and try shortening it up from there to try to bring that 3rd shot into the first two shots?

Question #3- Should I just stick with that 150 gr. BT load and scrap the ABLR since its a hunting rifle that will primarily be used for antelope, deer, and the occasional elk?

Maybe, but it is not possible to say with the data you have. Were it my rifle, I'd play with seating depth.

That would be a good plan. On the BTs, they tend to like loads that are seated near the lands.

Question #3- Should I just stick with that 150 gr. BT load and scrap the ABLR since its a hunting rifle that will primarily be used for antelope, deer, and the occasional elk?

I'd prefer a tougher bullet than the 150 grain BT for elk. It will work if shot placement is correct, but the shoulder of an elk is pretty tough.

On the ABLR load, what were your velocities? If they showed low standard deviations, it would be worth working with seating depth.

I agree with what Mikes saying. Adjust seating depth some more. I bet it'll come around.

I have found you have to really hang them out due to the tangent ogive. Much like a scirrocc. Find what oal puts the bullet .060" off the lands and try retesting

Unfortunately i do not have a chronograph. The load info puts them in the 2950 fps if i am not mistaken. I think I will keep trying them but I am going to load them at diffrent depths and look for what it likes! Thanks!

 

[FOTIS]

My load for my 270 bee did 3285 fps and around .9" at 3.300"

I shortened it to 3.265: and bam! underr 1/2"! And this is from a WBY ultra light!

 

[SJB358]

That's a great looking group. One of those would do for about everything.

i have the series one vanguard also in the good ole 270 win. i found that in order to really tighten the group with my load i pillar and glass bedded the rifle and immediately started shooting less than 1/2" groups at 100 yds. my load is the 140 grn AB with 59 grns of H4831sc and a fed 210 primer seated at a COAL of 3.353. i am yet to try any of the ABLR bullets in this rifle but plan to try them and see what happens.

 

[Silentstalker]

I think I will pillar and glass bed this rifle and go from there! Thanks all! Good luck on your hunts!
